Usually when you use LDAP for NSS you have a caching daemon to cut down on the number of round trips and latency (every time you need to map a userID to a name requires a call to LDAP) so maybe your cache is not expiring the old entries yet. NSCD which comes with GLIBC is a common cache, otherwise SSSD or WINBIND are also commonly used. Restarting your cache should help.
