I am currently hosting an intranet web page on a linux (RHEL4.4) server. I needed to restrict access to a certain group, so I am authenticating Apache against our Active Directory. It is working perfectly for all of my 30+ users except for two. All user accounts are identical except for name. There are no messages in my /var/log/messages or /var/log/httpd/error_log that would give any hint. In fact, they appear to be authenticating properly, but receive a "You do not have permission to view..." in the browser. The site is located in /var/www/html/<site_name> and the owner of all files are Apache.Apache.
Here is the authentication from my /etc/httpd/conf/httpd.conf:
Allow from all
require group <group_name>
As stated, the authentication works perfectly for ever user except for two and I cannot for the life of me figure out why they would be denied. Their AD accounts are exactly the same as the others.
