LDAP authentication failure

I can't figure this one out.

I'm trying to migrate my user's authentication from NIS to LDAP.  I'm
using RHEL v3

On my server, I think I have everything set up okay.  I added the users
(after some trouble with the migration tools) and remove myself from
/etc/password, and /etc/shadow.  I ran authconfig and set it up to use
LDAP and not NIS.  I'm able to log onto the machine without any
problems.

Also, the root account was never migrated, only users.  I want the root
account to stay in /etc/password and /etc/shadow.  

On the client machines, I installed the openldap packages and ran
authconfig and told it to use my LDAP server, however users are not
being authenicated.  The logs give the following messages:

Apr 11 23:43:29 hydrogen sshd(pam_unix)[26530]: check pass; user unknown
Apr 11 23:43:29 hydrogen sshd(pam_unix)[26530]: authentication failure;
logname= uid=0 euid=0 tty=NODEVssh ruser=
rhost=pool-138-89-99-214.mad.east.verizon.net
Apr 11 23:43:33 hydrogen sshd(pam_unix)[26530]: check pass; user unknown
Apr 11 23:43:35 hydrogen sshd(pam_unix)[26530]: 1 more authentication
failure; logname= uid=0 euid=0 tty=NODEVssh ruser=
rhost=pool-138-89-99-214.mad.east.verizon.net

If I do 'ldapsearch -x 'uid=<my username>' on the client machine, it
shows the information for my user account.  I can't figure out what the
differences are, thus I'm not able to get user authentication working on
client machines.  If anyone can help me with this, I'd really appreciate
it.  Thanks,
