LDAP: Hangs during login under X

[H.S.Rai]

I am trying to setup LDAP for authentication purpose. For that I
installed NFS-kernel-server, openLDAP (slapd), phpLdapAdmin, samba,
NSCD on server machine.

I can create user for LDAP, which I can login from the server in text
as well as in graphics mode, and working fine. But from remote machine
graphic login hangs, but login through console is working fine.

I have installed nfs-common, libnss-ldap, libpam-ldap, and both server
and client are running on Ubuntu 6.06 (Dapper).

How can I solve this problem, which log file should I see? Is there
any possibility of bug in dapper which is having LTS?

Thanks in advance.
