[Samba] winbind seems to hang when the DC goes down instead of switching to the other available DC

[L.P.H. van Belle]

Hai Marco, 

Yes, best is to use the "localhost" dns setup as caching/forwarder only. 

All you need is for the forwarding is :  

zone "your.dnsdomain.tld" {
    type forward;
    forwarders { IP_DC1; IP_DC2; };
};

zone "168.192.in-addr.arpa" {
    type forward;
    forwarders { IP_DC1; IP_DC2; };
};


If you think its still to slow, remove 
> options attempts:2
Or set 
> options attempts:1



Greetz, 

Louis
