Get Max uidNumber ...

["C.Lee Taylor" <leet@leenx.co.za>]

Greetings ...

	I search the archives and found that there was a few ideas how to do 
this, so I thought that I would though out my idea and see you guys bash 
it ... no pun intended ... I know this would be slow if one was tring to 
bring in more than a few users, but then I use it just to add a few 
users at a time ... I also believe this would not be a good idea to have 
more than one user adding in users, because the uidNumber could go up 
while we import the next user.

	Take look and tell me what you think ...
