If you use the rid backend, any uidNumbers & gidNumbers in AD are
ignored, the users UID will be calculated from this: ID = RID - BASE_RID
+ LOW_RANGE_ID
So if you have two users with the RIDs of 9999 & 10001, their UIDs would
be this (note BASE_RID is 0 unless set in smb.conf), LOW_RANGE_ID would
be set to 3000
UID = 9999 - 0 + 3000
Which would become: UID = 12999
UID = 10001 - 0 + 3000
Which would become: UID = 13001
These are just a couple of examples, from which I hope you can see,
provide you set the LOW_RANGE_ID lower than your lowest RID, it should
work, of course you will probably have to set the builtin range way
above your workgroup range.
