I have a redhat 9 server that is hosting a website using php/apache. It handles user logins by ldap and active directory. Everything works however my clients are reporting that after a week they are unable to login. A reboot of the server fixes the problem, however I'd rather know whats happening and fix it then have them reboot the server once a week. (yes its crossed my mind to run a cron every week to reboot).
I need help looking at logs to find out whats happening. Thanks!
