Users can't login to Filr

I found this TID hoping that was problem, but it's not.
Support | Authentication Failure when using LDAP for Authentication

We're strictly AD, Server 2012.

I tried using IP and DNS names for the server. Right now we're NOT using secure LDAP.

I tried several users. None have worked except for the admin user. I removed and re-added my LDAP source. Users get pulled in just fine, but they can't login. I purge some and re-imported, but still nothing.

I get this in the logs:
[com.novell.teaming.module.authentication.impl.Plus AuthenticationProviderModule] - Authentication failure for [testuser] org.springframework.security.authentication.BadCre dentialsException: Bad credentials

Not sure where to go from here.
