We have a more than one server that is responsible for creating users in
LDAP. We wrote a daemon that is responsible for dishing out the next
available uidNumber and managing the current set of uidNumberss. Instead
of trying to determine the uidNumber through LDAP, we consult the daemon.
The daemon uses a dbm to keep track of the uidNumbers in use. The daemon
will also notify us if there is a uidNumber conflict.
