I recently upgraded all of our servers to Ubuntu 16.04 and I'm using the Express version of Centrify Suite 2016 along with Centrify enabled Samba. I'm noticing that after a few days, adbindd dies on our systems and I must restart centrifydc-samba in order to get Samba shares working again. I can't find anything obvious in the logs as to why adbindd service stops, but it's happening on all servers with Ubuntu 16.04.
A few days after restarting centrifydc-samba, users report not being able to connect to network shares. When this happens I observe the following:
/etc/init.d/centrifydc-samba status
nmbd (pid 2298) is running...
winbindd (pid 2679 2348 2345 2318 2313) is running...
adbindd is stopped
smbd (pid 18973 18765 2689 2336 2329) is running...
Has anyone seen this behavior?
Here's some basic info:
