Re: Translucent Proxy to filter users

Hello, I'm trying to use our corporate openldap server for authentication to an application server (Github Enterprise) that does not support any "memberof" filters for allowed users.

As a workaround, I am looking into a translucent proxy server that would only return a subset of users. Github Enterprise would only "see" a few hundred users instead of thousands. Is this doable? Is there a better solution?

You could certainly work on an appropriate back-{ldap,relay,etc} configuration, but it's probably needless weight. Assuming the client supports a bindDN, I'd consider creating an ACL that only allows access to "a subset of users" that's desired and disallows !subset users. Oversimplified:

access to * group.expand="cn=githubgroup" by "cn=githubbinddn" read
access to * by "cn=githubbinddn" none
