I have winbind set up to authenticate to our AD for samba shares. This is the third such server, and the only one having any issues. It seems after a random amount of time samba shares will just stop working. Winbind processes seem to be running but restarting them seems to fix the issue for a while.
Looking at the logs have been kind of hit an miss and I don't know exactly when it fails. One interesting thing is that it seems to be pulling from another domain controller that it shoudlnt. I censored out the domain name in this example. But isnt there some way to block authentication to a domain? I'm not sure if this is a symptom or a cause of the issue.
