[Samba] Preventing winbind from crashing while KDC is unreachable

[Bjoern Meier]

hi,

we have here a multi-domain environment and my question is: is that a
wanted behavior, that winbind crashed with "error looking up domain
users" if a KDC isn't available and winbind had to be restarted to
work again?
We have a maintainance rotation for server an network.  So I wanted,
that Winbind notice for itself if the one specific KDC is on again (he
is not really down, but unreachable).

Thanks for helping.

Greetings Björn
