[Samba] When re-joining domain.

[PITFALL]

Dear All:

Samba will assign uid according to the range of idmap uid destined in 
smb.conf when join domain. The question is: Does samba force to reassign the 
uid each time joining domain?
For example: idmap uid =10000-50000
Join first time, the domain users uid will start from 10000 according to 
alphabetical order. 
Join the same domain second time, the domain users uid will still start from 
10000 according to alphabetical order. 
What if after joining domain, some user deleted and thus the alphabetical 
order is not the same as first join? The users after the deleted user will 
shift up by 1 when joining the second time. Is there anyway to work around 
the problem?

Thanks for your reply.
