All LDAP users are blocked on login

I cannot figure out what is wrong with my ldap setup, I did a packed capture and the LDAP bind was successful, and the LDAP user is created properly, but it always blocks the account. Manually unblocking the account doesn’t help, the next LDAP authentication blocks it again.

I’ve tried ldaps and regular ldap, also anonoymous bind, but none of it makes any difference.

I’ve tried removing the ldap identity for the user as some other people have suggested and it didn’t help. I have also manually unblocked the user via rake, but that didn’t help either.

Is there some missing step, where I have to add users to a group or something, before LDAP auth works properly?

Any pointers?

I just figured it out.

I think the optional attributes are the problem:

  username: [‘uid’, ‘userid’, ‘sAMAccountName’]
  email: [‘mail’, ‘email’, ‘userPrincipalName’]

I changed it to:

  username: ‘uid’
  email: ‘mail’

And it started working.

Maybe all those attributes have to exist for it not to fail?
