Hi everyone, I'm trying to figure out the best way to accomplish below project and would appreciate your input. I need to setup a web page on CentOS with Active Directory authentication. So far I've accomplished the following: - Setup httpd.conf to successfully authenticate against AD by passing my username/passwd. <Directory /var/www/html/secure> Allow from All AuthType Basic AuthName "Ldap test area" AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthLDAPURL "ldap://server:389/OU=OU=name,OU=area,DC=core,DC=test,DC=edu?sAMAccountName?sub?(objectClass=*)" AuthLDAPBindDN "username at core" AuthLDAPBindPassword password require valid-user </Directory> - In addition, I used LikeWise software and was able to successfully join AD. I was wondering if there is a way to do http authentication without passing my username/password considering server is already binded to AD, thus authenticated. Would I be able to utilize PAM authentication for this purpose? # httpd -v Server version: Apache/2.2.3 Server built: Aug 30 2010 12:28:40 # more /etc/redhat-release CentOS release 5.5 (Final) Thank you!
