Try running 'net cache flush'
Also, the numbers I supplied were examples, you may need to tweak them.
The 'rid' backend calculates the the Unix ID from the users RID with
ID = RID + LOW_RANGE_ID
Which from the range I posted becomes:
ID = RID + 500
So, if a user has the RID 1000, they should have the ID '1500'
1500 = 1000 + 500
The '*' range is for the Well Known Sids and anything outside the domain
These numbers will probably not match any users you have /etc/passwd
(mind you, you shouldn't have any users in /etc/passwd)
