[SATLUG] LDAP auth

[robert c3]

I've got several boxes where I'm doing LDAP authentication through PAM.
I've got a user with a 5 character UID who can't log into my Debian
(Sarge & Etch) boxes but logs in just fine on my RHEL4 machines.  Any
ideas?  If I change his UID to a 6 character UID, it works on the Debian
machines.

The non-working DN looks like:
uid=smith,ou=People,dc=my,dc=domain,dc=com

If I change it to:

uid=smith2,ou=People,dc=my,dc=domain,dc=com

it works.

Any ideas?

Thanks,
Robert
