This is how we handle assigning uids and gids. An object contains the next
number to be used, when that gets used the app updates the value to x+1. We
added a lock attribute that can be set to Y to tell application to wait until
it goes to N. Not perfect probably but it works, since only two people add
account object locking simply isn't that big a deal for us (two accounts
created/removed a week).
