[Samba] winbind failover not working

[Krzysztof Adamski]

Hi,

I have a Ubuntu server 12.4.LTS running version 3.6.3 of winbindd.
I use the MS AD to authenticate users, this works fine while there is no 
problems with the AD server.
If the AD server reboots the winbind never switches to other AD servers, 
there are 4 here.

I used this to joint the domain:
net join -U admin createcomputer="OU=Servers,OU=abc,DC=domain,DC=com

I can't find anything on the Ubuntu box that would make it only connect 
to 1 AD server.

Any ideas what I could do to be able to use more then one AD server?

Regards,
K
