I was using winbind to log in using windows ad accounts for a while with no problems, then after an update to the fedora server a few days ago logins using a.d. accounts failed repeatedly. Oddly if I issue the wbinfo - u right before trying to log in; the lo gin with an a.d. account succeds. I'm curious if anyone else has been experiencing this problem. I'm also curious how others approach updates to their fedora boxes; especially production servers. My experience has left me with a feeling of "once it's working; don't mess with it" ?
