Overview
This tutorial will show how to set up an Authentication Provider in Spring Security to allow for additional flexibility compared to the standard scenario using a simple UserDetailsService.
The Authentication Provider
Spring Security provides a variety of options for performing authentication - all following a simple contract - an Authentication request is processed by an AuthenticationProvider and a fully authenticated object with full credentials is returned.
The standard and most common implementation is the DaoAuthenticationProvider - which retrieves the user details from a simple, read only user DAO - the UserDetailsService. This User Details Service only has access to the username in order to retrieve the full user entity - and in a large number of scenarios, this is enough.
More custom scenarios will still need to access the full Authentication request to be able to perform the authentication process - for example, when authenticating against some external, third party service (such as Crowd) - both the username and the password from the authentication request will be necessary.
For these, more advanced scenarios, we'll need to define a custom Authentication Provider:
@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {
@Override
public Authentication authenticate(Authentication authentication) throws AuthenticationException {
String name = authentication.getName();
String password = authentication.getCredentials().toString();
// use the credentials to try to authenticate against the third party system
if (authenticatedAgainstThirdPartySystem()) {
List grantedAuths = new ArrayList<>();
return new UsernamePasswordAuthenticationToken(name, password, grantedAuths);
} else {
throw new AuthenticationException("Unable to auth against third party systems");
}
}
@Override
public boolean supports(Class authentication) {
return authentication.equals(UsernamePasswordAuthenticationToken.class);
}
}
Notice that the granted authorities set on the returned Authentication object are empty - this is because authorities are of course application specific.
Register the Auth Provider
Now that the Authentication Provider is defined, we need to specify it in the XML Security Configuration, using the available namespace support
Do authentication
Requesting Authentication from the Client is basically the same with or without this custom authentication provider on the back end - we can use a simple curl command to send an authenticated request:
curl --header "Accept:application/json" -i --user user1:user1Pass http://localhost:8080/spring-security-custom/api/foo/1 Note that - for the purposes of this example - we have secured the REST API with Basic Authentication.
And we get back the expected 200 OK from the Server:
HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Set-Cookie: JSESSIONID=B8F0EFA81B78DE968088EBB9AFD85A60; Path=/spring-security-custom/; HttpOnly Content-Type: application/json;charset=UTF-8 Transfer-Encoding: chunked Date: Sun, 02 Jun 2013 17:50:40 GMT
Conclusion
In this article we discussed an example of custom authentication provider for Spring Security. The implementation can be found in the github project - this is an Eclipse based project, so it should be easy to import and run as it is.
