Login attempt failed. help in diagnosis of cause

I have no idea how to trace this nondescript log entry. Notification “Login attempt failed” shows up about every 3 seconds. I’m just logged into the front end with chrome. just shutdown all browsers, and it is still logging activity, samba and ssh windows are turned off too. any advice? (some says its appdaemon, not sure if I even have that).
