I followed the guide below as a starting point for my squid proxy, however authentication fails after a day or so (i think due to account reset) I am using squid 3.2.6 with msktutil ERROR: Negotiate Authentication validating user. Error returned 'BH NT_STATUS_ACCESS_DENIED' I am running a cronjob daily with msktutil --auto-update, but from the message above this seems more like samba related issue. anyone seen this or have suggestions ? http://wiki.squid-cache.org/ConfigExamples/Authenticate/WindowsActiveDirectory
