Can I suggest you read this:
winbind will do what you require, I cannot comment on , sssd has
NOTHING to do with Samba. I also cannot recommend using , from
examining the script, it would appear that it would be possible to get
the same ID for two users from different domains e.g. if we take these
It appears the script would take a portion of the end of the SID, add
'0' the the RID, so they could be:
How would Samba and Unix tell them apart ?
Windows could tell the two SID-RIDs apart.
