[xwiki-users] Active Directory / LDAP lockouts

Hey all, I have an instance of XWiki running that is integrated with Active Directory. 99% of the time, users are able to log in without issues. However, once in a while (every month or two), a user will get kicked off (signed out and their credentials no longer work). After a couple hours, they are able to log in perfectly fine. During this time, other users have no login issues and using a different browser, clearing cookies/cache, etc do not seem to help at all. Additionally, the user can still log into other systems that use Active Directory with those same credentials. It also doesn't look like this is happening because of a password reset as far as I can tell; today a user was locked out but their last password reset was last week some time. Does anyone have any ideas about what might be causing this, or at least know how to narrow it down to figure out if it's an XWiki issue or if it's something else? I have been poking around through the log files but I haven't been able to see anything out of the ordinary.
