[Bug 1078699] Re: winbind won't start at boot

[Clint Byrum]

Ok, first off, winbind.conf has this old relic start on

start on (local-filesystems and net-device-up IFACE!=lo)
stop on runlevel [!2345]

This will start winbind as soon as *any* network interface is up, which
is not what we want. The appropriate conditions are:

start on runlevel [2345]
stop on runlevel [^2345]

This will make sure that winbind waits for all of the interfaces in
/etc/network/interfaces to be up.

Now, in the lsb-init script from Debian:

# Should-Start:      samba

This means that winbind needs to ensure samba is started before it
starts. Now, samba is broken up into smbd and nmbd in the Ubuntu
packages. So the pre-start should really have this:

if [ -f /etc/init/smbd.conf ] ; then
    start wait-for-state WAITER=winbind WAIT_FOR=smbd
fi
# repeat for nmbd

However, its not entirely clear if any of this will actually solve the
issue reported here. Nevertheless, its stuff that needs to happen.

Diego, is there any way you can look through the logs on an affected
system and find the error messages from winbind? I thin it logs
somewhere in /var/log/samba.

Title:
  winbind won't start at boot

Status in “samba” package in Ubuntu:
  Incomplete

Bug description:
  Winbind, by default, gets started too early (S20), resulting in daemon termination and impossible login w/ users from AD.
  If I connect as a local admin and restart winbind service, all goes well.

  3) expected # service winbind status
   * winbind is running
  4) getting # service winbind status
   * winbind is not running

  I tried to change S20winbind to S80winbind in /etc/rc*.d but seems it still gets started too early.
  An ugly workaround is starting it from rc.local, delaying for a minute or so... but it's really too ugly!
