We have a data share that's on a server that's part of domain A. We have users in domain B with user accounts in domain A that need to access this share. On pc's this works fine and up until last week it worked on the macs as well. Now on the macs (in either domain) we get an authentication failure when we try to mount it using the "GO, TO SERVER" from the mac toolbar. Unfortunately my mac guy is out of town and I don't see any indication on the Active Directory side what's going wrong. On the macs I've tried to tail some of the logs in /var/log but I get "access denied" on all of them. Is there any logging on the macs I can check to see what's failing?
