[Samba] samba + kerberos + active directory with multiple domains

[Winkel, Richard J.]

Could someone just send me a working config that works with multiple ad 
domains?  Anything would be helpful...

Thanks!

But it won't allow me to specify a domain as part of the userid.  I can set a default domain in smb.conf and logging into that domain works like a champ.  And I can list the other domains with "wbinfo --online-status" (not sure what "offline" means but I can list the groups even in the offline domains).  But if I turn off the default domain in smb.conf
