Well, I don't want it to know about LDAP. That's why I have the pam_ldap module, right?
Are you implying that with pam_unix alone (and nss_ldap) I can make this whole authentication
thing work?
I once sent a message to padl about this and they told me that with only nss_ldap I would
be able to authenticate users only with crypt-style passwords. And still somewhat limited.

But going back to the pam_pwdb issue, I know it will fail if a user is only in the LDAP
directory (it even logs that in /var/log/messages), but then it tries pam_ldap and
succeeds. What would be the difference with pam_unix?

OK, thanks a lot! I will try it out.
