Subject:   Issues while authenticating a user over openLDAP using PAM_ldap
Message-ID:  <46BB69EF.9070400@enabled.com>

Next in thread | Raw E-Mail | Index | Archive | Help
running FreeBSD 6.2 Stable

we have openLDAP installed on a server called access1.  Users on access1
appear to not be able to ssh to access1.  The ssh authentication method
uses PAM ldap.  PAM_ldap reports "Invalid credentials" in /var/log/messages

We have another server called access2 that authenticates to the the ldap
server running on access1.  those users log in via ssh without issue on
access2.

I am trying to track down what is broken.  I am not even sure how to
receive verbose logging from PAM and/or PAM_ldap.  Any assistance is
much appreciated.
