Does authentication ever fail like this from another login point (from a desktop login, or other PAM settings)? Or only when apache is involved?Everyone, Here is a challenge for all of you samba experts! Lately I have been seeing a problem where winbind is not correctly identifying a user as a member of a group he most certainly belong to. This is with a Domain Local group so I know samba should support it. Users access a HTTPS (SSL) webpage that is secured by a Domain Local group. Sometimes they get in, others they don't. Here are some examples from the logs./var/log/apache2/error_log [Tue Feb 12 18:54:52 2008] [error] [client 172.xx.xxx.xxx] GROUP: NA\\selltc not in required group(s)., referer: https://ustr-linux-1/scm/spar/trac/browser/trunk/common/include/channels [Tue Feb 12 18:55:00 2008] [error] [client 172.xx.xxx.xxx] GROUP: NA\\selltc not in required group(s)., referer: https://ustr-linux-1/scm/spar/trac/browser/trunk/common/include/channels [Tue Feb 12 18:56:12 2008] [error] [client 172.xx.xxx.xxx] GROUP: NA\\selltc not in required group(s)., referer: https://ustr-linux-1/scm/spar/trac/browser/trunk/common/include/channels However a little later it is mysteriously working again... /var/log/apache2/access_log 172.xx.xxx.xxx - NA\\selltc [12/Feb/2008:20:02:37 -0500] "GET /scm/spar/trac/chrome/common/css/trac.css HTTP/1.1" 304 - 172.xx.xxx.xxx - NA\\selltc [12/Feb/2008:20:02:37 -0500] "GET /scm/spar/trac/chrome/common/css/browser.css HTTP/1.1" 304 - 172.xx.xxx.xxx - NA\\selltc [12/Feb/2008:20:02:37 -0500] "GET /scm/spar/trac/chrome/common/css/diff.css HTTP/1.1" 304 - Now obviously my example doesn't have the user accessing the same link, but it doesn't matter. Winbind went from identifying the user as not in the group to then identifying him as in the group and nothing changed! This is happening several times a day and is driving us insane. What can I do to figure this out? Has anyone else seen this? Here is what is going on in the /var/log/samba/log.wb-NA (our domain) log at that time for that user.
