If it's a wild goose chase it's my fault. He is having trouble with
some commercial software when run by domain users instead of local
The differences between them as far as I could tell are:
The local users all have UIDs and primary group IDs << 65536.
The domain users all have UIDs and primary group IDs >> 65536.
Also, the primary group name of the domain users is "Domain Users".
i.e. it has a space in it.
Since traditionally UIDs and GIDs were 16 bit numbers, I thought it
was possible that this commercial software somehow did not like the
Perhaps it would be easier to test a local user with a high UID and
primary group ID to see if that also does not work.
