I guess that rules out the "object isn't there" theory. Are your Thunderbird users authenticating to the directory? The pam_ldap module needs to convert the user name to the distinguished name of an entry in the directory server before it can attempt to bind to that entry with the user's password, so you need to provide the ability to locate an entry using its "uid" attribute in order for things to work.
