GDM & ldap authentication problems

["Mike OConnor" <moconnor syc net au>]

Hi All

Over the last few week, our IT team has implemented an ldap system
which allow us to configure email, samba, mailing list and posix account
from one location.

Today I tried to get our ltsp server to use the ldap posix accounts.

Doing a 'getent passwd' shows all the accounts from password files and
ldap

An ldap account was able to login via ssh.

BUT :)

If I try to login via gdm, it complains that the username or password is
incorrect and the following is logged.

syslog - messages:
Jan  7 11:27:19 yaad-xserver02 gdm(pam_unix)[13729]: session closed for
user test1 Jan  7 11:29:13 yaad-xserver02 gdm(pam_unix)[14564]: check
pass; user unknown Jan  7 11:29:13 yaad-xserver02 gdm(pam_unix)[14564]:
authentication failure; logname= uid=0 euid=0 tty=localhost.localdomain:1

user (from getpwnam(moconnor)) Jan  7 11:29:14 yaad-xserver02 gdm[14564]:
Couldn't set acct. mgmt for moconnor

If we change the gdm pam.d file to reflect the follow url.
http://www.google.com.au/search?q=cache:q7iGpATw4_gC:www.cosc.canterbury.ac.nz/~mpj17/ldap/+ldap+gdm&hl=en&ie=UTF-8

We are able to get past username/password but get an error saying 'Could
not set your group,  etc'

syslog - messages:
Jan  7 12:33:07 yaad-xserver02 gdm[15565]: Cannot set user group for dross
Jan  7 12:34:46 yaad-xserver02 gdm: Only root wants to run gdm

We are using redhat 7.1, with a gdm which I build from source gdm-2.2.5


Does any one had any idea what is wrong ?

Thanks
