Hi Jay/Samba peeps,

Emailing in reference to http://lists.samba.org/archive/samba/2011-April/162277.html

I have seen a very similar issue with a similar setup.

Users fail to be verified with:

getent passwd username

Entry in the log at same time is:

[2012/01/23 16:58:53.159761, 3] winbindd/winbindd_misc.c:352(winbindd_interface_version)
  [18510]: request interface version

  getpwnam username
[2012/01/23 16:58:53.162493, 5] winbindd/winbindd_getpwnam.c:138(winbindd_getpwnam_recv) Could not convert sid S-1-5-21-1117850145-1682116191-196506527-126617: NT_STATUS_PIPE_BROKEN

Restarting winbindd solves the problem temporarily.

I've attached a copy of the smb.conf.

OS:     Debian Squeeze 6.0.3
Kernel: 2.6.32-5-686-bigmem
samba   2:3.5.6~dfsg-3squeeze5
winbind 2:3.5.6~dfsg-3squeeze5

Jay did you find a solution to your problem? Has anyone else on the list seen similar issues or have any ideas of what might be happening?

Any advice or pointers would be very much appreciated.

Thanks,

Matt
