I've gone through Greg's HOW-TO on getting Samba to authenticate with Zimbra LDAP, and have hit a wall. I've exhausted my searches and don't know how to troubleshoot this any further.
I have it to the point where I can create new users and when I issue the "smbclient -U newuser //samba.domain.com/newuser" it asks for the password and connects fine. However, I can't get it to authenticate with pre-existing users. I've modified the schema for the existing user, verified that they are being added in the Samba server with "getent passwd" but I can't login with that user. It just says "NT_STATUS_LOGON_FAILURE"
Also, I can't login via the console with either a newly created user or a pre-existing user. Should I be able to do this? It doesn't seem to make sense why I would be able to authenticate a new user, but not an old one when it should be looking at the same LDAP server. Where can I look to see what I am missing? Thanks for your help!
Also, I just noticed that the sambaNTPassword field under the Samba Account tab is blank for the pre-existing user, but it is not blank for the newly created users.
