mod_authnz_ldap and lookup

The Apache module mod_authnz_ldap allows an LDAP directory to be used to store the database for HTTP Basic authentication. In this wiki page we are going to explain how to use this module in conjunction with the lookup LDAP service and mod_ucam_webauth.

If you require more deep information than the one provided in this page, you can visit the lookup LDAP service webpage and/or the Apache mod_authnz_ldap webpage

Compatibility

All these examples have been tested with Apache 2.4. The same directives could be used for Apache 2.2.

Security

Include the following directive to the mod_ldap configuration to make sure that all connections make by Apache to the LDAP server are secure. Modify the file /etc/apache2/mods-enabled/ldap.conf and add

 LDAPTrustedMode TLS

Basic documentation

Only allow access to members of an institution (InstID)

 AuthType Ucam-WebAuth
 AuthLDAPUrl ldap://ldap.lookup.cam.ac.uk/ou=people,o=University%20of%20Cambridge,dc=cam,dc=ac,dc=uk?uid
 <RequireAll>
   Require valid-user
   Require ldap-filter instID=UIS
 </RequireAll>


Only allow access to members of any institution (InstID) in the RequireAny list

 AuthType Ucam-WebAuth
 AuthLDAPUrl ldap://ldap.lookup.cam.ac.uk/ou=people,o=University%20of%20Cambridge,dc=cam,dc=ac,dc=uk?uid
 <RequireAll>
   Require valid-user
   <RequireAny>
     Require ldap-filter instID=UIS
     Require ldap-filter instID=CL
   </RequireAny>
 </RequireAll>


Allow access only to the users with crsids listed in RequireAny

 AuthType Ucam-WebAuth
 AuthLDAPUrl ldap://ldap.lookup.cam.ac.uk/ou=people,o=University%20of%20Cambridge,dc=cam,dc=ac,dc=uk?uid
 <RequireAll>
   Require valid-user
   <RequireAny>
     Require ldap-user amc203
     Require ldap-user jw35
     Require ldap-user jml4
   </RequireAny>
 </RequireAll>


Allow access only member of any of the groups listed in the RequireAny tag and in the ldap query

 AuthType Ucam-WebAuth
 AuthLDAPUrl ldap://ldap.lookup.cam.ac.uk/ou=groups,o=University%20of%20Cambridge,dc=cam,dc=ac,dc=uk?uid??|(groupID=101611)(groupID=101855)
 <RequireAll>
   Require valid-user
   <RequireAny>
     Require ldap-attribute groupID=101855
     Require ldap-attribute groupID=101611
   </RequireAny>
 </RequireAll>

(where 101611=UIS staff and 101855=UIS test accounts).

Groups should be identified by numeric ID since names could be duplicated (maliciously or accidentally), causing failure or bogus matches and consequent authorisation.
