[Bug 1291951] [NEW] winbind loose domain join after reboot

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

After a reboot we have to rejoin our server to the domain.

I think, it has something to do, that file in /var/run/ (and
/var/cache/? ) get cleared on reboot.

We connect to a Windows 2008 R2 Domain Controller.
