[Samba] domain controller's unavailability

[Vladimir Vassiliev]

Hello,

Is there any way to reliably setup winbind user and group resolution (in either smb.conf or 
nsswitch.conf) so that domain controller's unavailability doesn't cause slowdown of the whole 
system? That slowdown applies to every program trying to fetch some user information even when it 
doesn't need domain users.

I have
winbind cache time = 1800
in smb.conf but it doesn't work reliably for some reason. Also I would try nscd but some sources 
claim it's not compatible with winbind. Is that true?

Thanks.
