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.
All these examples have been tested with Apache 2.4. The same directives could be used for Apache 2.2 but these haven't been tested.
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
Only allow access to members of any institution (InstID) in the Require list

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

(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.
