In my application, there are more than 100 users. How can put their username password and roles in the below code?
I have tried so many logic but could not succeed.
auth
.inMemoryAuthentication()
.withUser("user").password("password").roles("USER").and()
.withUser("operator").password("password").roles("OPERATOR").and()
.withUser("admin").password("password").roles("ADMIN").and();

I wanted to ask about good JWT authentication practices. I need to protect half of my endpoints in my spring backend where only administrator may call them from my rest Vue api and rest of them may be called only from vue native application where users will be logged in. How should I do it?
Best regards!
This can be achieved using spring security authorities in your userdetails, so an admin user will have and admin role and a normal user will have a user role.
Then the endpoints can be protected based on the roles
#PreAuthorize("hasRole('ROLE_ADMIN')")
public List<Foo> findAll() { ... }

I have application with Spring security. It's REST api for Angular SPA. It uses session and cookie mechanism. Now I want to access this api from mobile application (Nativescript). I spent some time searching for best way to authenticate mobile app user. In the most cases oauth2 and jwt tokens are advised. So I've done reasearch on this and decided to add additional (seperate) authentication only for mobile application. So Angular app still will be using session with path api/... and mobile app will be using token mechanism with path /api/mobile/... (underneath it will be the same api but with different prefix).
I've decided to use OAuth2 and its Spring integration. I've read documentation and I'm consfused. Why they always mention about authentication provider (Google, Github, Facebook)? I don't want to force my users to login via other service. I want to allow them login with credentials they already registered with in my application. How this social login even related with oAuth authorization server? All examples they've provided use some other services.
I've also tried to add my authorization server in my existing app. I've successfully retrieved token. But now I don't understand all this relationships. There is authorization server that keeps client id and client server. But why /auth/token endpoint needs another authentication? So mobile app needs to provide 3 different credentials - user credentials, client id and secret and token endpoint credentials.
Did I miss something? I know that OAuth is only specification and Spring is implementation of it. But I'm under impression that Spring overcomplicates this. And do I need oauth at all since I have only 1 type of resource?
#Configuration
#EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {
#Override
public void configure(ClientDetailsServiceConfigurer configurer) throws Exception {
configurer
.inMemory()
.withClient(clientId)
.secret(passwordEncoder.encode(clientSecret))
.authorizedGrantTypes("refresh_token", "authorization_code", "password", "implicit")
.scopes(scopeRead, scopeWrite)
.resourceIds(resourceIds);
}
}
I've built a REST Service using Spring Boot and Spring Security for authentication. I'm pretty new to both Spring Boot and Spring Security. I've made one authentication module in one JAR file. The front end client sends a request with username and password to the authentication module. The authentication module then authenticates the user's details against a DB. A JWT is created and then sent back to the client if the authentication is successful. The username and role is coded into the JWT. The JWT is then used to verify the user when resources are requested from the other REST Service endpoints that are built in separate JAR files. There are a few things I'm not sure about.
In Spring Security is there one authentication object created for each user so that several users can be authenticated at the same time or is one authentication done each time and only one user can be logged in?
How long is the authentication object in valid? Should I "logout"/remove the authentication successful when the JWT has been created in the authentication module or will it take care of it itself when the request is done? For the resource endpoints (not the authentication endpoint) is there a way to set authentication successful in the authentication object once I've verified the JWT? Similarly can I set the role in the authentication object once the JWT has been verified?
I've based my code on this example https://auth0.com/blog/securing-spring-boot-with-jwts/. I've split it into different JARs for authentication and verification of the JWT (I'm doing verification in resource endpoint). I've also added JDBC authentication instead of in memory authentication.

Of course multiple users can be authenticated at the same time!

You write your service is REST, and if you want to stay "puritan" REST you should configure the authentication to be stateless, which means that the Authentication object is removed when the request has been processed. This does not affect the validity of the JWT token, you can set an expiry of JWT token if you want.
How to make REST stateless with "Java config":
#Configuration
public static class RestHttpConfig extends WebSecurityConfigurerAdapter
{
#Override
protected void configure(HttpSecurity http) throws Exception
{
http
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS);
// and the rest of security config after this
For the resource endpoints (not the authentication endpoint) is there
a way to set authentication successful in the authentication object
once I've verified the JWT? Similarly can I set the role in the
authentication object once the JWT has been verified?
I use code similar to below after verification of the token:
Collection<? extends GrantedAuthority> authorities = Collections.singleton(new SimpleGrantedAuthority("ROLE_JWT"));
Authentication authentication = new PreAuthenticatedAuthenticationToken(subject, token, authorities);
SecurityContextHolder.getContext().setAuthentication(authentication);
By constructing the authentication object with at least one role (authority), it is marked as "successful" (authenticated).
In my application I am using multiple authentication handlers like application DB, LDAP and SAML. Now after successful authentication I am using CustomAuthenticationSuccessHandler.java which extends SimpleUrlAuthenticationSuccessHandler class which will be called after successful authentication. My question is how to get information about which handler has a successful authentication. I need this information because if it is an external user (LDAP, SAML) then I have to write a logic to replicate the user in application DB.
My configuation in configure global method:
auth
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
auth
.ldapAuthentication()
.ldapAuthoritiesPopulator(ldapAuthoritiesPopulator)
.userDnPatterns("uid={0},ou=people")
.userDetailsContextMapper(ldapUserDetailsContextMapper)
.contextSource(getLDAPContextSource());`
You can set the info to authentication detail when do authenticated, or you can use different Authentication instances, e.g UsernamePasswordAuthenticationToken for DB and LDAP(maybe need to create a new Authentication to separate them), SAMLAuthenticationToken for SAML.
I have successfully used spring security to login users. But the issue is, right now on my web page, when a new user is created, he/she has to again go back to sign in page to login which of course uses spring security. Is there a way to login the user automatically using Spring Security as soon as a new user is created?
do this
UserDetails userDetails = userDetailsService.loadUserByUsername(username);
UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken (userDetails, password2, userDetails.getAuthorities());
authenticationManager.authenticate(auth);
if(auth.isAuthenticated()) {
SecurityContextHolder.getContext().setAuthentication(auth);
}
I have never done it, but i think you should do what it is described in the doc.
Once the request has been authenticated, the Authentication will
usually be stored in a thread-local SecurityContext managed by the
SecurityContextHolder by the authentication mechanism which is being
used. An explicit authentication can be achieved, without using one of
Spring Security's authentication mechanisms, by creating an
Authentication instance and using the code:
SecurityContextHolder.getContext().setAuthentication(anAuthentication);
Note that unless the Authentication has the authenticated property set to true, it will still be authenticated by any security interceptor (for method or web invocations) which encounters it.
