samba - Feb 2013 - gid collision

Hi

Setup is samba 3.6.3 on ubuntu 12.04.1, domain member server in a
Win2008R2 DC environment. Userauth is via kerberos.

I have a gid collision I cannot find an answer for. Please see below.

root at python:/home/DOMAIN/users# ls -la
drwxr-x--- 4 user1 PYTHON\none  136 Dez  7 09:42 user1
drwxr-x--- 2 user2 PYTHON\none    6 Jan 30 11:01 user2
drwxr-x--- 2 user3 PYTHON\none    6 Jan 30 11:13 user3

root at python:/home/DOMAIN/users# getent group 'domain users'
domain users:x:100513:
root at python:/home/DOMAIN/users# getent group 'python\none'
PYTHON\none:x:100513:

neither wbinfo -g nor getent group list any group named python\none.

Has anybody got an explanation for python\none or how I get rid of it?

Thanks
Philipp

Hi

I switched in nsswitch.conf

group: files winbind
to
group: winbind files

and rebooted the box. PYTHON\none has dissapeared. getent group
'python\none' and wbinfo --group-info='python\none' haven't
got any
results anymore.

It feels quite strange that by changing name resolution order behaviour
like that dissapears. Is this a bug?

Thanks,
Philipp
