Authentication Provider Spring Security 5 - spring

I have my WebSecurityConfigurerAdapter class with use an AuthenticationProvider
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(fusionAuthProvider);
}
Then in fusionAuthProvider in the authenticate() method is the flow to authenticate.
I'm developing and API RESTful. So, there is a way that I can say that i want to use that provider when i hit a certain endpoint like "/login_with_that_provider", using a controller or something like that?

spring boot using 2 different oauth providers at the same time

I'm facing a use where I have to check oauth token against 2 different oauth provider given an input context (private call to may api vs public call)
Is there a simple way to define 2 oauth provider in spring boot and how to configure this balancing between the 2 providers ?
First you will need to implement 2 AuthenticationProvider then in your configuration class that implements WebSecurityConfigurerAdapter you would autowire those providers. Finally override the public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception { to add those providers.
#Configuration
public class SampleAuthConfiguration extends WebSecurityConfigurerAdapter {
#Autowired
private CustomAuthenticationProvider1 provider1;
#Autowired
private CustomAuthenticationProvider2 provider2;
#Override
public void configure(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
authenticationManagerBuilder
.authenticationProvider(this.provider1)
.authenticationProvider(this.provider2);
}
}
Below are some tutorials. The may be outdated but may help you to figure it out.

Spring Boot Security + Spring Boot REST Repository config issue

I have Spring boot application as below
And the Web Security Config as
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated().and().formLogin();
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
// #formatter:off
auth.inMemoryAuthentication().withUser("chiru").password("{noop}chiru").roles("ADMIN").and().withUser("user")
.password("{noop}user").roles("USER");
// #formatter:on
}
}
And the i have Repository as below
public interface IssuesRepository extends CrudRepository<Issues, Integer> {
}
when i try to add data through REST Using Postman with Basic Authentication, its failing
Use httpBasic() instead of formLogin(), like http.authorizeRequests().anyRequest().authenticated().and().httpBasic();.
formLogin() is used when you want to have login page to authenticate the user (so you have), but in your example you are using http basic to do that. Spring security doesn't recognizes your http basic header and returns login page.
PS. You can use both methods http.httpBasic().and().formLogin()

Spring Security with OAuth2 and anonymous access

I have my Spring REST API secured with Spring Security and OAuth2, I can successfully retrieve a token and access my APIs. My App defines the OAuth2 client itsself.
Now I want users to have anonymous access on some resources. The use case is really simple: I want my app to be usable without login - but if they are logged in, I want to have access to that principal.
Here is my WebSecurityConfigurerAdapter so far:
#Override
protected void configure(HttpSecurity http) throws Exception {
http.antMatcher("/api1").anonymous().and()
.authorizeRequests().antMatchers("/ap2**").permitAll();
}
As soon as I add a second antMatcher/anonymous, it fails to work though, and it doesn't really express my intent either - e.g. I wan't to have anonymous access on api1 GETs, but authenticated on POSTs (easy to do with #PreAuthorize).
How can I make the OAuth2 authentication optional?
I dropped my #EnableWebSecurity and used a ResourceServerConfigurerAdapter like so:
#Configuration
#EnableResourceServer
protected static class ResourceServer extends ResourceServerConfigurerAdapter {
#Override
public void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers(HttpMethod.GET, "/api/api1", "/api/api2").permitAll()
.and().authorizeRequests()
.anyRequest().authenticated();
}
#Override
public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
resources.resourceId("my-resource-id");
}
}
/api/api1 may now be called with or without authentication.

Spring security java config basic authentication filter

I am trying to add basic authentication for my APIs where the users will be authenticated based on their credential stored in MongoDB. I want to use java config instead of XML based config. So far what I have learnt is I have to create #Configuration by extending WebSecurityConfigurerAdapter and override configure method. In that I can add a custom filter by addFilterBefore().
But how can I get a Authentication header information in the filter, how to proceed if the user is authenticated. I have been googling a lot but didn't find any good example that will help a novice like me whose been into spring just for 1 week.
Does any one have a good tutorial or sample that can help me get started with this? Thanks in advance.
As example, you can use next solution.
#Override
protected void configure(HttpSecurity http) throws Exception {
http.httpBasic().authenticationEntryPoint(getBasicAuthenticationEntryPoint());
}
#Bean
public BasicAuthenticationEntryPoint getBasicAuthenticationEntryPoint(){
BasicAuthenticationEntryPoint basicAuthenticationEntryPoint = new BasicAuthenticationEntryPoint();
basicAuthenticationEntryPoint.setRealmName("Basic Authentication");
return basicAuthenticationEntryPoint;
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth
.userDetailsService(userDetailsService)
.passwordEncoder(passwordEncoder());
}
It works for me. But you need to implement UserDetailsService interface.
Spring automatically checks is user authenticated and tries to proceed authentication if not.

spring security not able to add custom authentication providers

I have created additional authentication providers. I am registering them like following:
#Configuration
#EnableWebMvcSecurity
#EnableGlobalMethodSecurity(prePostEnabled = true)
class SecurityConfig extends WebSecurityConfigurerAdapter{
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(tokenAP());
auth.authenticationProvider(usernameAndPasswordAP());
auth.userDetailsService(getUserDetailsService());
}
Later in my code I am using AuthenticationManager to authenticate users. The issue is that I have only one authentication provider registered in authentication manager which is DaoAuthenticationProvider. It looks like my authentication providers are not registered at all. Should I do some additional config to make it work? I am using spring boot 1.2.6 Thanks in advance for any tips. Best Regards
When you override the configure(AuthenticationManagerBuilder auth), the underlying AuthenticationManager is exposed in one of 2 ways:
1) within SecurityConfig, you can simply call authenticationManager()
2) if you need AuthenticationManager outside of your SecurityConfig you will need to expose it as a bean, for example:
class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(tokenAP());
auth.authenticationProvider(usernameAndPasswordAP());
auth.userDetailsService(getUserDetailsService());
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}
The way we have authentication providers configured in our Spring Boot web applications is similar to what is discussed in the example Spring Security Java configuration from the current release reference guide, which modifies the default autowired AuthenticationManagerBuilder. Using your methods, it might look like:
#Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(tokenAP())
.authenticationProvider(usernameAndPasswordAP())
.userDetailsService(getUserDetailsService());
}
If I am reading the Javadocs for the configure(AuthenticationManagerBuilder) method correctly, when you override this method you must specify your own AuthenticationManager. By using the autowired instance as described above, the default AuthenticationManager (which is ProviderManager, which in turn delegates to one or more configured AuthorizationProvider instances).
You may also need to annotate your configuration class with:
#Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
So that your access control rules are applied before the defaults that Spring Boot will otherwise configure for you.
