[Samba] Winbind backend : rid is too much underappreciated

[Miguel Medalha]

What do you think of this possible extension to the rid backend?

A small schema extension would be done to the SAMBA Active Directory. Then, 
on  domain provision with the samba-tool we would input the wanted rid 
backend range. A single parameter in the smb.conf of each new member 
server would make it read this information from the DC and automatically 
configure itself with that range. The benefits of centralized management 
of UID/GID without the pain of manual labor.
