Auth problem with openldap and nss_ldap

[Johnny PINSON <johnny.pinson@univ-reims.fr>]

Hey,

I installed an openldap client and nss_ldap on a linux computer running
slackware. Then I modified /etc/nsswitch.conf, adding ldap to authentify
thanks a ldap server.

The commands "getent password" and "id" are working. When I'm root and
doing a "su $user", I'm able to su as $user. But, if I try to log in as
$user, I get everytime an "invalid password".

What can I do please to get i working? Would you need copy of my config
files?

Thanks a lot,
