[Bug 1291951] Re: winbind loose domain join after reboot

[Michael Rodrigues]

Turns out the tdbbackup method was a red herring. What I am seeing
though is that I can use "net ads testjoin" to rebind without having to
authenticate. Running this with debug I see that the
/var/run/samba/smb_krb5/krb5.conf.DOMAIN file is generated.

Title:
  winbind loose domain join after reboot

Status in “samba” package in Ubuntu:
  Confirmed

Bug description:
  After a reboot we have to rejoin our server with "net ads join -U
  administrator" to the domain.

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

  We connect to a Windows 2008 R2 Domain Controller.
