What is the default AuthenticationManager in Spring-Security? How does it authenticate?

The AuthenticationManager is really just a container for authentication providers, giving a consistent interface to them all. In most cases, the default AuthenticationManager is more than sufficient.

When you call

.authenticate(new UsernamePasswordAuthenticationToken(username, password))`

it is passing the UsernamePasswordAuthenticationToken to the default AuthenticationProvider , which will use the userDetailsService to get the user based on username and compare that user’s password with the one in the authentication token.

In general, the AuthenticationManager passes some sort of AuthenticationToken to the each of it’s AuthenticationProviders and they each inspect it and, if they can use it to authenticate, they return with an indication of “Authenticated”, “Unauthenticated”, or “Could not authenticate” (which indicates the provider did not know how to handle the token, so it passed on processing it)

This is the mechanism that allows you to plug in other authentication schemes, like authenticating against an LDAP or Active Directory server, or OpenID, and is one of the main extension points within the Spring Security framework.

org.springframework.security.authentication.AuthenticationManager.authenticate java code examples

Authentication

Attempts to authenticate the passed Authentication object, returning a fully populatedobject (including granted authorities) if successful.

An AuthenticationManager must honour the following contract concerning exceptions:

A DisabledException must be thrown if an account is disabled and the AuthenticationManager can test for this state.

can test for this state. A LockedException must be thrown if an account is locked and the AuthenticationManager can test for account locking.

can test for account locking. A BadCredentialsException must be thrown if incorrect credentials are presented. Whilst the above exceptions are optional, an AuthenticationManager must always test credentials.

Exceptions should be tested for and if applicable thrown in the order expressed above (i.e. if an account is disabled or locked, the authentication request is immediately rejected and the credentials testing process is not performed). This prevents credentials being tested against disabled or locked accounts.
