Public bug reported:
Binary package hint: coreutils
id 5.97 fails to report secondary groups depending on the case of the
username.
Example: If you have an Ubuntu domain member Samba server on a
NT4/Win2k/Win2k3 network, the following occurs (from a posting in the
Samba mailing list):
--------------------------------------
With the "normal" setup (winbind use default domain = No):
id DOMAINNAME\\username - shows all groups
id DOMAINNAME\\USERNAME (or any permutation with a cap in the username) - only
primary groups
id username - returns "No such user" (normal)
--------------------------------------
If I set "winbind use default domain = Yes" then:
id DOMAINNAME\\username - only primary groups
id DOMAINNAME\\USERNAME (or any permutation with a cap in the username) - only
primary groups
id Username - (or any permutation with a cap in the username) - only primary
groups
id username - shows all groups
--------------------------------------
These are all valid examples that should all yield the same results
containing all groups for the user.
Some versions will also list, or not list secondary groups depending on
whether or not the user issuing the id command as root.
I have seen this behaviour in id 5.97, but not in 5.2.1 (pre-rewrite?).
It seems to work fine for me in id 6.7, but I have seen a report of another
user claiming that 6.7 also fails.
Why do we care?: Because it potentially sends server operators on wild
goose chases trying to debug Samba(winbind) when the fault actually is
with id. The id utility is one of the tools used to verify a new
winbind setup is functioning properly. I have seen several postings on
various newsgroups and lists over the last few years mentioning this
problem without the users realizing the problem may originate with a bug
in id.
