Problem with gdm auth

[lozingalo]

Hi

i configured an ldap server on debian squeeze and a client ubuntu 10.04.

Trying to login from login screen of the client using ldap user credentials it doesn't accept it.
Trying from a shell with the command

su - nslcd_proc

it runs.

Checking in /var/log/auth.log i found these messages:

Apr  4 15:50:51 dello gdm-session-worker[3414]: pam_succeed_if(gdm:auth): error retrieving information about user nslcd_proc

What could i do to resolve it?

thanks

And how about login from a local LDAP user? It happens the same?

A similar situation is described here:

FC11 GDM can't authenticate users from LDAP
https://bugzilla.redhat.com/show_bug.cgi?id=505319

That's for Redhat but you can read the comments to get an idea on what can
be going on at your Debian box.
