Identity Brokering are for Web SSO IdPs. It works by redirecting the user.
User federation works by reading users from external sources.
Kerberos when used with LDAP is just an authenticator, but there's also a
federation provider so it can be used without LDAP in which case only the
username is available and the rest has to be filled in manually by the user.

Identity provider is a redirect and user has to click a button or you setup
the default one.
User federation works by looping through providers until a match for the
username is found.

You may not have configured it properly and it can't find the user within
LDAP. Test connection / authentication just checks that Keycloak can
connect to LDAP, not that it can find a specific user.
