I got a question the other day: “Can we set up blogs for each of our staff, that only certain people in our area can read?”.
Well, I immediately thought of WordPress MU, and possibly some sort of Active Directory (via LDAP) authentication or similar.
It turns out there’s an LDAP Authentication plugin already created. So, we’d need some sort of additional plugin to specify only certain AD groups should be permitted to read the blog.
Excellent, now we just need a server to host it on… Oh, damn, I knew there was a catch!
Others are already doing this (or something similar), and seem to be reasonably happy, despite a few problems (such as the 11-tables-per-user thing).
