Hi, Maybe someone overhere can help me with this issue. I'm trying to authenticate an apache website against an Active Directory LDAP service. I already got it working properly when I want to check if a user is in a certain container in the AD. But I want to change authentication using an AD group because users from other containers also need access. I run into the problem that I can log in but I almost always get a webpage with an error message: "internal server error". After refreshing the page a lot of times I get to see the correct webpage. Then, after a couple of minutes, again the website shows an "internal server error" again. So something is going wrong, but I don't know what. It's strange cause authenticating users in a container works without any problems. I'm not sure it's an apache configuration error but here is my config: Group access (this one gives me problems): <Directory "/usr/local/nagios/sbin"> Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all AuthBasicProvider ldap AuthType Basic AuthzLDAPAuthoritative on AuthName "Nagios Access" AuthLDAPURL "ldap://ezhdc01:389/dc=elisabeth,dc=nl?sAMAccountName?sub?(objectClass=*)" #AuthLDAPURL "ldap://ezhdc01:389/dc=elisabeth,dc=nl?sAMAccountName?sub?(objectCategory=person)" AuthLDAPBindDN "cn=sa_nagios,ou=Service Accounts,ou=admins,dc=elisabeth,dc=nl" AuthLDAPBindPassword "**********" Require ldap-group cn=APP_Nagios,ou=Applicaties,ou=Groups,ou=EZH,dc=elisabeth,dc=nl #Require valid-user #AuthLDAPGroupAttributeIsDN on </Directory> Users in a certain container example (this one works alright and gives me no problem): <Directory "/usr/local/nagios/sbin"> AuthzLDAPAuthoritative on AuthName "Nagios Access" Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all Require valid-user AuthLDAPURL "ldap://ezhdc01:389/ou=Users,ou=admins,dc=elisabeth,dc=nl?sAMAccountName?sub?(objectClass=*)" AuthLDAPBindDN "cn=sa_nagios,ou=Service Accounts,ou=admins,dc=elisabeth,dc=nl" AuthLDAPBindPassword "***********" </Directory> -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
