As written, upstream bug 13332 only covers the case of DC reboot, not
the DC down cases in my bug:

- DC down or broken, should failover to another DC, not fail completely.
- All DCs down, should recover once at least one DC is up.
- All DCs down at winbind start, should recover once at least one DC is up.


Enjoy
