I'm using Spring Boot 1.5.4, Spring Data REST, Spring Security. I created a #Controller mapped to a specific path that doesn't require authentication because it used from a sms gateway for report incoming texts.
So I've just to create a controller to read those parameters and then save the text on the db. And here there is the problem. To store data I use repositories that are secured, while in the controller I've not any kind of security (in fact I cannot ask the provider to secure its calls).
I tried to set an authentication context programatically but seems not working:
#Controller
#RequestMapping(path = "/api/v1/inbound")
#Transactional
public class InboundSmsController {
private Logger log = LogManager.getLogger();
#RequestMapping(method = RequestMethod.POST, path = "/incomingSms", produces = "text/plain;charset=ISO-8859-1")
public ResponseEntity<?> incomingSms(#RequestParam(name = "Sender", required = true) String sender,
#RequestParam(name = "Destination", required = true) String destination,
#RequestParam(name = "Timestamp", required = true) String timestamp,
#RequestParam(name = "Body", required = true) String body) {
log.info(String.format("Text received from %s to %s at %s with content: %s", sender, destination, timestamp, body));
setupAuthentication();
try {
int transitsWithSameTextToday = transitCertificateRepository.countByTextAndDate(body, Instant.now()); //This is the method that raises an Auth exception
....
....
} finally(){
clearAuthentication();
}
SecurityContext context;
/**
* Set in the actual context the authentication for the system user
*/
private void setupAuthentication() {
context = SecurityContextHolder.createEmptyContext();
Collection<GrantedAuthority> authorities = AuthorityUtils.createAuthorityList("ROLE_ADMIN");
Authentication authentication = new UsernamePasswordAuthenticationToken("system", "ROLE_ADMIN", authorities);
context.setAuthentication(authentication);
}
private void clearAuthentication() {
context.setAuthentication(null);
}
The method countByTextAndDate is annotated with #PreAuthorize("isAuthenticated()")
I'm surprised also setting the Auth context I've this error. Am I doing something wrong? Is this the best way to reach my goal?
I don't want to annotate my method with #PermitAll because that method is also exposed by Spring Data REST and I don't want anyone can use that.

I am trying to call SOAP API in Java Spring Boot using WebServiceGatewaySupport by Spring WebServiceTemplate
Config java class
public WebServiceTemplate createWebServiceTemplate(Jaxb2Marshaller marshaller, ClientInterceptor clientInterceptor) {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();
//SOAP URL
webServiceTemplate.setDefaultUri("http://host/Services.asmx");
//Auth ---It seems issue is here only????? need to check
webServiceTemplate.setMessageSender(new Authentication());
webServiceTemplate.setMarshaller(marshaller);
webServiceTemplate.setUnmarshaller(marshaller);
webServiceTemplate.afterPropertiesSet();
webServiceTemplate.setCheckConnectionForFault(true);
webServiceTemplate.setInterceptors((ClientInterceptor[]) Arrays.asList(createLoggingInterceptor()).toArray());
return webServiceTemplate;
}
SOAP Client Call
public class TicketClient extends WebServiceGatewaySupport {
public String getTicket(Ticket req) {
System.out.println("test inside webservice support1");
response = (AcquireTicketResponse) getWebServiceTemplate().marshalSendAndReceive(req);
Authentication Class
public class Authentication extends HttpUrlConnectionMessageSender {
#Override protected void prepareConnection(HttpURLConnection connection) {
String userpassword = username+":"+password+":"+domain;
String encoded =
Base64.getEncoder().withoutPadding().encodeToString(userpassword.getBytes(StandardCharsets.UTF_8));
connection.setRequestProperty("Authorization", "Basic "+encoded); connection.setRequestProperty("Content-Type", "application/xml"); super.prepareConnection(connection);
}
Not using Authetication class and add the above into
ClientInterceptor
public class SoapLoggingInterceptor implements ClientInterceptor {
#Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
String username="test";
String password="test";
String domain = "#test";
String userpassword = username+":"+password+domain;
String encoded = Base64.getEncoder().withoutPadding().encodeToString(userpassword.getBytes(StandardCharsets.UTF_8));
messageContext.setProperty("Authorization", "Basic "+encoded);
messageContext.setProperty("Content-type", "XML");
Case -1 --->When I passed (user, pwd, domain and content-type) through messagesender, content type is taking but throwed "BAD REQUEST ERROR 400"....When i comment contenttype property, then it throwed "INTERNAL SERVER ERROR 500".
Case-2...when I passed (user, pwd, domain and content-type) through ClientInterceptor , always it throwed "INTERNAL SERVER ERROR 500"......It seems Authentication properties for the service are not going to API call.............................Please suggest some options
Both the cases, Authentication is not passing to service, if i comment,Authentication code (userid/pwd/domain) in both cases also...no efforts in output
After setting the user ID/pwd
#Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
String username="test";
String password="test";
String domain = "#test";
String userpassword = username+":"+password+domain;
byte[] userpassword = (username+":"+password).getBytes(StandardCharsets.UTF_8);
String encoded = Base64.getEncoder().encodeToString(userpassword);
ByteArrayTransportOutputStream os = new
ByteArrayTransportOutputStream();
try {
TransportContext context = TransportContextHolder.getTransportContext();
WebServiceConnection conn = context.getConnection();
((HeadersAwareSenderWebServiceConnection) conn).addRequestHeader("Authorization", "Basic " + encoded);
} catch (IOException e) {
throw new WebServiceIOException(e.getMessage(), e);
}
First of all don't set the content type Spring WebServices will do that for you, messing around with that will only make things worse.
You should get the WebServiceConnection and cast that to a HeadersAwareSenderWebServiceConnection to add a header.
public class BasicAuthenticationInterceptor implements ClientInterceptor {
#Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {
String username="test#test";
String password="test";
byte[] userpassword = (username+":"+password).getBytes(UTF_8);
String encoded = Base64.getEncoder().encodeToString(userpassword);
WebServiceConnection conn = TransportContext.getConnection();
((HeadersAwareSenderWebServiceConnection) conn).addHeader("Authorization", "Basic " + encoded);
}
}
You also need to configure it. Assuming it is a bean don't call afterPropertiesSet (and ofcourse you are now using the ClientInterceptor remove the new Authentication() for your customized message sender.
The List<ClientInterceptor> will automatically create a list with all the interceptors so you can easily inject them.
#Bean
public WebServiceTemplate createWebServiceTemplate(Jaxb2Marshaller marshaller, List<ClientInterceptor> clientInterceptors) {
WebServiceTemplate webServiceTemplate = new WebServiceTemplate(marshaller);
//SOAP URL
webServiceTemplate.setDefaultUri("http://host/Services.asmx");
webServiceTemplate.setCheckConnectionForFault(true);
webServiceTemplate.setInterceptors(clientInterceptors);
return webServiceTemplate;
}
If this doesn't work there is something else you are doing wrong and you will need to get in touch with the server developers and get more information on the error.
Update:
Apparently you also need to provide a SOAP Action in your request, which you currently don't. For this you can specify the SoapActionCallback in the marshalSendAndReceive method. Which action to specify you can find in the WSDL you are using.
SoapActionCallback soapAction = new SoapActionCallback("SoapActionToUse");
response = (AcquireTicketResponse) getWebServiceTemplate().marshalSendAndReceive(req, soapAction);
I have an endpoint in RestController. When request would be processed , there must performed redirecting to another URL and There need to pass one parameters in redirect URL.
#RestController
#RequiredArgsConstructor
#Slf4j
public class RestControllerImpl {
#Value("${uri-root}")
private String uriRoot;
private final Service service;
#PostMapping("/api")
public RedirectView performRequest(#RequestBody Transaction dto) {
service.perform(dto);
String referenceToken = "sldflh#2lhf*shdjkla"
String urlRedirect = uriRoot + "?token=" + referenceToken;
return new RedirectView(urlRedirect);
}
}
The code above doesn't work for me.
I was looking for information on stackoverflow, but it suggests either using ModelAndView or RedirectAttributes attributes. But I need endpoint to accept a Post request that would bring data that will be processed in the service layer.
It is not possible to complete this task. Could someone explain how this can work and how such a task can be accomplished ?
It worked.
#RestController
#RequiredArgsConstructor
#Slf4j
public class RestControllerImpl {
#Value("${uri-root}")
private String uriRoot;
private final Service service;
#PostMapping("/api")
public ResponseEntity createClient(#RequestBody Transaction dto) throws URISyntaxException {
service.perform(dto);
String referenceToken = "sldflh#2lhf*shdjkla"
String urlRedirect = uriRoot + "?token=" + referenceToken;
return ResponseEntity.created(new URI(urlRedirect)).build();
}
}
Link for Authorization server: https://github.com/spring-projects/spring-authorization-server
This project pretty much has everything in terms of OAuth and Identity provider.
My question is, How to achieve multi-tenancy at the Identity provider level.
I know there are multiple ways to achieve multi-tenancy in general.
The scenario I am interested in is this:
An organization provides services to multiple tenants.
Each tenant is associated with a separate database (Data isolation including user data)
When a user visits dedicated Front-end app(per tenant) and negotiate access tokens from Identity provider
Identity provider then identifies tenant (Based on header/ Domain name) and generates access token with tenant_id
This access token then is passed on to down-stream services, which intern can extract tenant_id and decide the data source
I have a general idea about all the above steps, but I am not sure about point 4.
I am not sure How to configure different data sources for different tenants on the Identity Provider? How to add tenant_id in Token?
Link to the issue: https://github.com/spring-projects/spring-authorization-server/issues/663#issue-1182431313
This is not related to Spring auth Server, but related to approaches that we can think for point # 4
I remember the last time we implemented a similar approach, where we had below options
To have unique email addresses for the users thereby using the global database to authenticate the users and post authentication, set up the tenant context.
In case of users operating in more than 1 tenant, post authentication, we can show the list of tenant's that the user has access to, which enables setting the tenant context and then proceeding with the application usage.
More details can be read from here
This is really a good question and I really want to know how to do it in new Authorization Server in a proper way. In Spring Resource Server there is a section about Multitenancy. I did it successfully.
As far as new Spring Authorization Server multitenancy concerns. I have also done it for the password and the Client Credentials grant type.
But please note that although it is working but how perfect is this. I don't know because I just did it for learning purpose. It's just a sample. I will also post it on my github when I would do it for the authorization code grant type.
I am assuming that the master and tenant database configuration has been done. I can not provide the whole code here because it's lot of code. I will just provide the relevant snippets. But here is just the sample
#Configuration
#Import({MasterDatabaseConfiguration.class, TenantDatabaseConfiguration.class})
public class DatabaseConfiguration {
}
I used the separate database. What I did I used something like the following in the AuthorizationServerConfiguration.
#Import({OAuth2RegisteredClientConfiguration.class})
public class AuthorizationServerConfiguration {
#Bean
#Order(Ordered.HIGHEST_PRECEDENCE)
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http) throws Exception {
OAuth2AuthorizationServerConfigurer<HttpSecurity> authorizationServerConfigurer = new OAuth2AuthorizationServerConfigurer<>();
....
http.addFilterBefore(new TenantFilter(), OAuth2AuthorizationRequestRedirectFilter.class);
SecurityFilterChain securityFilterChain = http.formLogin(Customizer.withDefaults()).build();
addCustomOAuth2ResourceOwnerPasswordAuthenticationProvider(http);
return securityFilterChain;
}
}
Here is my TenantFilter code
public class TenantFilter extends OncePerRequestFilter {
private static final Logger LOGGER = LogManager.getLogger();
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
String requestUrl = request.getRequestURL().toString();
if (!requestUrl.endsWith("/oauth2/jwks")) {
String tenantDatabaseName = request.getParameter("tenantDatabaseName");
if(StringUtils.hasText(tenantDatabaseName)) {
LOGGER.info("tenantDatabaseName request parameter is found");
TenantDBContextHolder.setCurrentDb(tenantDatabaseName);
} else {
LOGGER.info("No tenantDatabaseName request parameter is found");
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
response.setContentType(MediaType.APPLICATION_JSON_VALUE);
response.getWriter().write("{'error': 'No tenant request parameter supplied'}");
response.getWriter().flush();
return;
}
}
filterChain.doFilter(request, response);
}
public static String getFullURL(HttpServletRequest request) {
StringBuilder requestURL = new StringBuilder(request.getRequestURL().toString());
String queryString = request.getQueryString();
if (queryString == null) {
return requestURL.toString();
} else {
return requestURL.append('?').append(queryString).toString();
}
}
}
Here is the TenantDBContextHolder class
public class TenantDBContextHolder {
private static final ThreadLocal<String> TENANT_DB_CONTEXT_HOLDER = new ThreadLocal<>();
public static void setCurrentDb(String dbType) {
TENANT_DB_CONTEXT_HOLDER.set(dbType);
}
public static String getCurrentDb() {
return TENANT_DB_CONTEXT_HOLDER.get();
}
public static void clear() {
TENANT_DB_CONTEXT_HOLDER.remove();
}
}
Now as there is already configuration for master and tenant database. In these configurations we also check for the TenantDBContextHolder
class that it contains the value or not. Because when request comes for token then we check the request and set it in TenantDBContextHolder. So base on this thread local variable right database is connected and the token issue to the right database. Then in the token customizer. You can use something like the following
public class UsernamePasswordAuthenticationTokenJwtCustomizerHandler extends AbstractJwtCustomizerHandler {
....
#Override
protected void customizeJwt(JwtEncodingContext jwtEncodingContext) {
....
String tenantDatabaseName = TenantDBContextHolder.getCurrentDb();
if (StringUtils.hasText(tenantDatabaseName)) {
URL issuerURL = jwtClaimSetBuilder.build().getIssuer();
String issuer = issuerURL + "/" + tenantDatabaseName;
jwtClaimSetBuilder.claim(JwtClaimNames.ISS, issuer);
}
jwtClaimSetBuilder.claims(claims ->
userAttributes.entrySet().stream()
.forEach(entry -> claims.put(entry.getKey(), entry.getValue()))
);
}
}
Now I am assuming that the Resource Server is also configure for multitenancy. Here is the link Spring Security Resource Server Multitenancy. Basically You have to configure two beans for multitenancy like the following
public class OAuth2ResourceServerConfiguration {
....
#Bean
public JWTProcessor<SecurityContext> jwtProcessor(JWTClaimsSetAwareJWSKeySelector<SecurityContext> keySelector) {
ConfigurableJWTProcessor<SecurityContext> jwtProcessor = new DefaultJWTProcessor<>();
jwtProcessor.setJWTClaimsSetAwareJWSKeySelector(keySelector);
return jwtProcessor;
}
#Bean
public JwtDecoder jwtDecoder(JWTProcessor<SecurityContext> jwtProcessor, OAuth2TokenValidator<Jwt> jwtValidator) {
NimbusJwtDecoder decoder = new NimbusJwtDecoder(jwtProcessor);
OAuth2TokenValidator<Jwt> validator = new DelegatingOAuth2TokenValidator<>(JwtValidators.createDefault(), jwtValidator);
decoder.setJwtValidator(validator);
return decoder;
}
}
Now two classes for spring. From which you can get the tenant Identifier from your token.
#Component
public class TenantJwtIssuerValidator implements OAuth2TokenValidator<Jwt> {
private final TenantDataSourceRepository tenantDataSourceRepository;
private final Map<String, JwtIssuerValidator> validators = new ConcurrentHashMap<>();
....
#Override
public OAuth2TokenValidatorResult validate(Jwt token) {
String issuerURL = toTenant(token);
JwtIssuerValidator jwtIssuerValidator = validators.computeIfAbsent(issuerURL, this::fromTenant);
OAuth2TokenValidatorResult oauth2TokenValidatorResult = jwtIssuerValidator.validate(token);
String tenantDatabaseName = JwtService.getTenantDatabaseName(token);
TenantDBContextHolder.setCurrentDb(tenantDatabaseName);
return oauth2TokenValidatorResult;
}
private String toTenant(Jwt jwt) {
return jwt.getIssuer().toString();
}
private JwtIssuerValidator fromTenant(String tenant) {
String issuerURL = tenant;
String tenantDatabaseName = JwtService.getTenantDatabaseName(issuerURL);
TenantDataSource tenantDataSource = tenantDataSourceRepository.findByDatabaseName(tenantDatabaseName);
if (tenantDataSource == null) {
throw new IllegalArgumentException("unknown tenant");
}
JwtIssuerValidator jwtIssuerValidator = new JwtIssuerValidator(issuerURL);
return jwtIssuerValidator;
}
}
Similarly
#Component
public class TenantJWSKeySelector implements JWTClaimsSetAwareJWSKeySelector<SecurityContext> {
....
#Override
public List<? extends Key> selectKeys(JWSHeader jwsHeader, JWTClaimsSet jwtClaimsSet, SecurityContext securityContext) throws KeySourceException {
String tenant = toTenantDatabaseName(jwtClaimsSet);
JWSKeySelector<SecurityContext> jwtKeySelector = selectors.computeIfAbsent(tenant, this::fromTenant);
List<? extends Key> jwsKeys = jwtKeySelector.selectJWSKeys(jwsHeader, securityContext);
return jwsKeys;
}
private String toTenantDatabaseName(JWTClaimsSet claimSet) {
String issuerURL = (String) claimSet.getClaim("iss");
String tenantDatabaseName = JwtService.getTenantDatabaseName(issuerURL);
return tenantDatabaseName;
}
private JWSKeySelector<SecurityContext> fromTenant(String tenant) {
TenantDataSource tenantDataSource = tenantDataSourceRepository.findByDatabaseName(tenant);
if (tenantDataSource == null) {
throw new IllegalArgumentException("unknown tenant");
}
JWSKeySelector<SecurityContext> jwtKeySelector = fromUri(jwkSetUri);
return jwtKeySelector;
}
private JWSKeySelector<SecurityContext> fromUri(String uri) {
try {
return JWSAlgorithmFamilyJWSKeySelector.fromJWKSetURL(new URL(uri));
} catch (Exception ex) {
throw new IllegalArgumentException(ex);
}
}
}
Now what about authorization code grant type grant type flow. I get the tenant identifier in this case too. But when it redirects me to login page then I lost the tenant identifier because I think it creates a new request for the login page from the authorization code request. Anyways I am not sure about it because I have to look into the code of authorization code flow that what it is actually doing. So my tenant identifier is losing when it redirects me to login page.
But in case of password grant type and client credentials grant type there is no redirection so I get the tenant identifier in later stages and I can successfully use it to put into my token claims.
Then on the resource server I get the issuer url. Get the tenant identifier from the issuer url. Verify it. And it connects to the tenant database on resource server.
How I tested it. I used the spring client. You can customize the request for authorization code flow. Password and client credentials to include the custom parameters.
Thanks.
------------------ Solve the Authorization Code login problem for multitenancy -------------
I solved this issue too. Actually what I did in my security configuration. I used the following configuration
public class SecurityConfiguration {
.....
#Bean(name = "authenticationManager")
public AuthenticationManager authenticationManager(AuthenticationManagerBuilder builder) throws Exception {
AuthenticationManager authenticationManager = builder.getObject();
return authenticationManager;
}
#Bean
#DependsOn(value = {"authenticationManager"})
public TenantUsernamePasswordAuthenticationFilter tenantAuthenticationFilter(AuthenticationManagerBuilder builder) throws Exception {
TenantUsernamePasswordAuthenticationFilter filter = new TenantUsernamePasswordAuthenticationFilter();
filter.setAuthenticationManager(authenticationManager(builder));
filter.setAuthenticationDetailsSource(new TenantWebAuthenticationDetailsSource());
//filter.setAuthenticationFailureHandler(failureHandler());
return filter;
}
#Bean
public SecurityFilterChain defaultSecurityFilterChain(HttpSecurity http) throws Exception {
FederatedIdentityConfigurer federatedIdentityConfigurer = new FederatedIdentityConfigurer().oauth2UserHandler(new UserRepositoryOAuth2UserHandler());
AuthenticationManagerBuilder authenticationManagerBuilder = http.getSharedObject(AuthenticationManagerBuilder.class);
http.addFilterBefore(tenantAuthenticationFilter(authenticationManagerBuilder), UsernamePasswordAuthenticationFilter.class)
.authorizeRequests(authorizeRequests -> authorizeRequests.requestMatchers(new AntPathRequestMatcher("/h2-console/**")).permitAll()
.antMatchers("/resources/**", "/static/**", "/webjars/**").permitAll()
.antMatchers("/login").permitAll()
.anyRequest().authenticated()
)
......
.apply(federatedIdentityConfigurer);
return http.build();
}
Actually the problem was in case of Authorization Code is that you first redirect to login page. After successfully login you see the consent page. But when you comes to consent page then you lost the tenant parameter.
The reason is the spring internal class OAuth2AuthorizationEndpointFilter intercepts the request for Authorization Code. It checks user is authenticated or not. If user is not authenticated then it shows the login page. After successfully login it checks if consent is required. And if required then it makes a redirect uri with just three parameters. Here is the spring internal code
private void sendAuthorizationConsent(HttpServletRequest request, HttpServletResponse response,
OAuth2AuthorizationCodeRequestAuthenticationToken authorizationCodeRequestAuthentication,
OAuth2AuthorizationConsentAuthenticationToken authorizationConsentAuthentication) throws IOException {
....
if (hasConsentUri()) {
String redirectUri = UriComponentsBuilder.fromUriString(resolveConsentUri(request))
.queryParam(OAuth2ParameterNames.SCOPE, String.join(" ", requestedScopes))
.queryParam(OAuth2ParameterNames.CLIENT_ID, clientId)
.queryParam(OAuth2ParameterNames.STATE, state)
.toUriString();
this.redirectStrategy.sendRedirect(request, response, redirectUri);
} else {
if (this.logger.isTraceEnabled()) {
this.logger.trace("Displaying generated consent screen");
}
DefaultConsentPage.displayConsent(request, response, clientId, principal, requestedScopes, authorizedScopes, state);
}
}
See the above method is private and I found no way that I can customize it. May be there is but I didn't find it. Anyways now your consent controller is call. But there is no tenant Identifier. You can't get it. And after consent there is no way that it connects to tenant database base in identifier.
So the first step is to add tenant identifier to login page. And then after login you should have this tenant identifier so you can set it on your consent page. And after that when you submit your consent form then this parameter will be there.
Btw I did it some time ago and may be I miss something but this is what I did.
Now how you get your parameter at login page. I solved it using the following. First I created a constant as I have to access the name from multiple times
public interface Constant {
String TENANT_DATABASE_NAME = "tenantDatabaseName";
}
Create the following class
public class RedirectModel {
#NotBlank
private String tenantDatabaseName;
public void setTenantDatabaseName(String tenantDatabaseName) {
this.tenantDatabaseName = tenantDatabaseName;
}
public String getTenantDatabaseName() {
return tenantDatabaseName;
}
}
Then on my Login controller I get it using the following code
#Controller
public class LoginController {
#GetMapping("/login")
public String login(#Valid #ModelAttribute RedirectModel redirectModel, Model model, BindingResult result) {
if (!result.hasErrors()) {
String tenantDatabaseName = redirectModel.getTenantDatabaseName();
String currentDb = TenantDBContextHolder.getCurrentDb();
LOGGER.info("Current database is {}", currentDb);
LOGGER.info("Putting {} as tenant database name in model. So it can be set as a hidden form element ", tenantDatabaseName);
model.addAttribute(Constant.TENANT_DATABASE_NAME, tenantDatabaseName);
}
return "login";
}
}
So this is the first step that I have my tenant identifier in my login page that is send to me by request.
Now the configuration that I used in my Security configuration. You can see that I am using TenantUsernamePasswordAuthenticationFilter. Here is the filer
public class TenantUsernamePasswordAuthenticationFilter extends UsernamePasswordAuthenticationFilter {
private static final Logger LOGGER = LogManager.getLogger();
#Override
public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
throws AuthenticationException {
String tenantDatabaseName = obtainTenantDatabaseName(request);
LOGGER.info("tenantDatabaseName is {}", tenantDatabaseName);
LOGGER.info("Setting {} as tenant database name in thread local context.", tenantDatabaseName);
TenantDBContextHolder.setCurrentDb(tenantDatabaseName);
return super.attemptAuthentication(request, response);
}
private String obtainTenantDatabaseName(HttpServletRequest request) {
return request.getParameter(Constant.TENANT_DATABASE_NAME);
}
}
And in the configuration I am setting TenantWebAuthenticationDetailsSource on this filter which is here
public class TenantWebAuthenticationDetailsSource extends WebAuthenticationDetailsSource {
#Override
public TenantWebAuthenicationDetails buildDetails(HttpServletRequest context) {
return new TenantWebAuthenicationDetails(context);
}
}
Here is the class
public class TenantWebAuthenicationDetails extends WebAuthenticationDetails {
private static final long serialVersionUID = 1L;
private String tenantDatabaseName;
public TenantWebAuthenicationDetails(HttpServletRequest request) {
super(request);
this.tenantDatabaseName = request.getParameter(Constant.TENANT_DATABASE_NAME);
}
public TenantWebAuthenicationDetails(String remoteAddress, String sessionId, String tenantDatabaseName) {
super(remoteAddress, sessionId);
this.tenantDatabaseName = tenantDatabaseName;
}
public String getTenantDatabaseName() {
return tenantDatabaseName;
}
}
Now after spring authenticates the user then I have the tenant name in details. Then in the consent controller I use
#Controller
public class AuthorizationConsentController {
....
#GetMapping(value = "/oauth2/consent")
public String consent(Authentication authentication, Principal principal, Model model,
#RequestParam(OAuth2ParameterNames.CLIENT_ID) String clientId,
#RequestParam(OAuth2ParameterNames.SCOPE) String scope,
#RequestParam(OAuth2ParameterNames.STATE) String state) {
......
String registeredClientName = registeredClient.getClientName();
Object webAuthenticationDetails = authentication.getDetails();
if (webAuthenticationDetails instanceof TenantWebAuthenicationDetails) {
TenantWebAuthenicationDetails tenantAuthenticationDetails = (TenantWebAuthenicationDetails)webAuthenticationDetails;
String tenantDatabaseName = tenantAuthenticationDetails.getTenantDatabaseName();
model.addAttribute(Constant.TENANT_DATABASE_NAME, tenantDatabaseName);
}
model.addAttribute("clientId", clientId);
.....
return "consent-customized";
}
}
Now I have my tenant identifier on my consent page. After submitting it it's in the request parameter.
There is another class that I used and it was
public class TenantLoginUrlAuthenticationEntryPoint extends LoginUrlAuthenticationEntryPoint {
public TenantLoginUrlAuthenticationEntryPoint(String loginFormUrl) {
super(loginFormUrl);
}
#Override
protected String determineUrlToUseForThisRequest(HttpServletRequest request, HttpServletResponse response,
AuthenticationException exception) {
String tenantDatabaseNameParamValue = request.getParameter(Constant.TENANT_DATABASE_NAME);
String redirect = super.determineUrlToUseForThisRequest(request, response, exception);
String url = UriComponentsBuilder.fromPath(redirect).queryParam(Constant.TENANT_DATABASE_NAME, tenantDatabaseNameParamValue).toUriString();
return url;
}
}
Anyways this is how I solved it. I don't have any such requirement in any of my project but I want to do it using this new server so I just solved it in this way.
Anyways there is lot of code. I tested it using the Spring oauth2 client and it was working. Hopefully I will create some project and upload it on my Github. Once I will run it again then I will put more explanation here of the flow. Specially for the last part that after submitting the consent how it set in the Thread Local variable.
After that everything is straight forward.
Hopefully it will help.
Thanks
I have a spring boot application, which is MVC in nature. All page of this application are being authenticated by CAS SSO.
I have used "spring-security-cas" as described at https://www.baeldung.com/spring-security-cas-sso
Everything working fine as expected. However, I have one problem - that is, I cannot retrieve attributes
and username sent by the CAS server in the following #Bean. What need I do to retrieve all the attributes
and and username sent by the CAS server?
#Bean
public CasAuthenticationProvider casAuthenticationProvider() {
CasAuthenticationProvider provider = new CasAuthenticationProvider();
provider.setServiceProperties(serviceProperties());
provider.setTicketValidator(ticketValidator());
provider.setUserDetailsService(
s -> new User("casuser", "Mellon", true, true, true, true,
AuthorityUtils.createAuthorityList("ROLE_ADMIN")));
provider.setKey("CAS_PROVIDER_LOCALHOST_9000");
return provider;
}
First you will need to configure the attributeRepository source and the attributes to be retrieved, in attributeRepository section in CAS server, like:
cas.authn.attributeRepository.jdbc[0].singleRow=false
cas.authn.attributeRepository.jdbc[0].sql=SELECT * FROM USERATTRS WHERE {0}
cas.authn.attributeRepository.jdbc[0].username=username
cas.authn.attributeRepository.jdbc[0].role=role
cas.authn.attributeRepository.jdbc[0].email=email
cas.authn.attributeRepository.jdbc[0].url=jdbc:hsqldb:hsql://localhost:9001/xdb
cas.authn.attributeRepository.jdbc[0].columnMappings.attrname=attrvalue
cas.authn.attributeRepository.defaultAttributesToRelease=username,email,role
Check this example from CAS blog.
Then you need to implement an AuthenticationUserDetailsService at the service to read attributes returned from CAS authentication, something like:
#Component
public class CasUserDetailService implements AuthenticationUserDetailsService {
#Override
public UserDetails loadUserDetails(Authentication authentication) throws UsernameNotFoundException {
CasAssertionAuthenticationToken casAssertionAuthenticationToken = (CasAssertionAuthenticationToken) authentication;
AttributePrincipal principal = casAssertionAuthenticationToken.getAssertion().getPrincipal();
Map attributes = principal.getAttributes();
String uname = (String) attributes.get("username");
String email = (String) attributes.get("email");
String role = (String) attributes.get("role");
String username = authentication.getName();
Collection<SimpleGrantedAuthority> collection = new ArrayList<SimpleGrantedAuthority>();
collection.add(new SimpleGrantedAuthority(role));
return new User(username, "", collection);
}
}
Then, adjust your authenticationProvider with provider.setAuthenticationUserDetailsService(casUserDetailService);
We are implementing a simple health check API our load balancers can call to help with the routing of requests. If the status of the application is "standby", requests should not be sent to it. Only the admins can set the state to "up" or "standby", but anyone (including the load balancers) can get the status of the application.
We are trying this with Spring Boot 2, but are having problems configuring security to grant anonymous access to just one of the routes. Consider the following controller:
#RestController
public class AppStatusController {
private static final String STATUS = "status";
String state = "standby";
private String getState() {
return state;
}
private Map<String, String> getStatusMap() {
Map<String, String> retval = new HashMap<>();
retval.put(STATUS, getState());
return retval;
}
// GET calls are public, all others require AuthN & AuthZ
#GetMapping(path = "/appstatus", produces = "application/json")
public Map<String, String> getStatus() {
return getStatusMap();
}
// Only those with the ADMIN role can POST to this endpoint
#PostMapping(path = "/appstatus", consumes = "application/json", produces = "application/json")
public Map<String, String> setStatus(#RequestBody Map state) {
// Validate and update the state
return getStatusMap();
}
}
There is only one endpoint, /appstatus, but one method is called with an HTTP GET and the other with an HTTP POST. We want calls to getStatus to be public, but allow Spring Security to control access to setStatus. One might expect an annotation such as #Anonymous or something similar to be applied to the getStatus() method but we can't seem to find one.
Some have suggested using a separate #Configuration class and setting up antMatchers but it's not clear how we can match on the HTTP method.
Does anyone have suggestions on how to configure Spring Security to allow public access to GET method requests but control access to other methods?
EDIT: We are trying to avoid any authentication on the getStatus() call. We can't store auth credentials in the health check probe and can't perform a login exchange. This is a simple GET request to see if the application is up and ready for operation.
Have you tried using Method Security Expressions?
It looks like this will do what you want:
// GET calls are public, all others require AuthN & AuthZ
#GetMapping(path = "/appstatus", produces = "application/json")
#PreAuthorize("permitAll")
public Map<String, String> getStatus() {
return getStatusMap();
}
// Only those with the ADMIN role can POST to this endpoint
#PostMapping(path = "/appstatus", consumes = "application/json", produces = "application/json")
#PreAuthorize("hasRole('ADMIN')")
public Map<String, String> setStatus(#RequestBody Map state) {
// Validate and update the state
return getStatusMap();
}
Note: I don't know what roles your admins have, so I used 'ADMIN' as a placeholder.
