Hello,
I set up a test instance of MediaWiki at our site and am trying to get it
configured for LDAP authentication. Per the documentation I could find, I
installed and configured the following extensions:
- LDAPAuthentication2
- LDAPAuthorization
- LDAPProvider
- PluggableAuth
Without LDAPAuthorization enabled, basic LDAP authentication works fine.
However, when I enable LDAPAuthorization and try to filter access by
membership in a specific group, authentication fails every time with an
error saying the user is not authorized.
More specifically, I created a group in our LDAP system called wiki-users
and added myself as a member. I then added an authorization block to the
json file and specified the full DN of this group as a required group. I'm
using plaintext LDAP so I can run packet captures and see the traffic.
When I capture the LDAP traffic, I can see that it's authenticating the
bind user and then my own user, but at no point does it query for this
group.
A sanitized version of my json file is pasted below. Any help is greatly
appreciated!
