Each to their own, but most of the stuff is fairly generic. I've written
the scripts to read the ldap settings from the relevent files (the admin
user, and the user & group context).

Yuch! And what happens if the information gets out of sync. I've come up
with a solution, which was much easier than I had thought -
user_base=`awk '/nss_base_passwd/ {print $2}' /etc/ldap.conf | cut -f1 -d?`
get_next_uid() {
lastuid=`ldapsearch -LLL -b "$user_base"
"objectclass=posixAccount" |\
awk '/uidNumber/ {print $2}' | sort | tail -n1`
if [ -z "$lastuid" ]; then
uid=$startuid
else
uid=`expr $lastuid + 1`
fi
}
it pulls out all the uids already assigned, sorts them, takes the last
one, and adds one on (or sets it to startuid if none found). It might fall
over if huge numbers of users are in there, but should work for most.

Thats another task - I'm just interested in easily adding and removing
users easily.
If you are interested, I can send you the full scripts - they are pretty
sparse and general, so should be easy to adapt.
Cheers,
