Hi everyone,
We get the next available uidNumber by:

# get the next free uidNumber
getent passwd | cut -d ":" -f3 | sort -n > /tmp/uid.txt
maxnum=$(sort -n /tmp/uid.txt |tail -1)
uid=$(expr $maxnum + 1)
echo "Next available uidNumber = $uid"

It's worked for 100 users and a few groups so far without any collisions.

The main problem is that gidNumber does not get pulled from the 
directory for us at the moment. So we have a different range of 
gidNumber. E.g. group RID+20000 works for groups and makes it all 
readable. E.g. a uidNumber is 3000241, a gidNumber is 21108. Easily 

Please tell me how wrong this is.
