No, the '*' range is for the 'well known SIDs' (see here:
https://support.microsoft.com/en-us/kb/243330) and anything outside
your domain (aka workgroup).
The suggested ranges on the samba wiki are known to work (well, they
work for me). They allow for local Unix users & groups in the range
1000-1999, for the well known SIDs in the range 2000-9999 and domain
users & groups in the range 10000-999999
The local Unix users & groups will get their IDs when they are added
and they will be created in /etc/passwd and /etc/group.
The well known SIDs will be allocated an ID, starting from 2000 i.e.
the start number for the range
You will have to add unique uidNumber attributes to each user, starting
from 10000, you must also give 'Domain Users' a gidNumber attribute,
you can use 10000 for this (yes, you can have a user with uidNumber
10000 and a group with the same number)
If everything is installed and setup correctly and you run 'getent
passwd auser' you should get something like this:
rowland at devstation:~$ getent passwd rowland
Any further questions, just ask ;-)
