I've been experimenting with a MW related project after all this time away.
No-one is in IRC so I had two minor questions I needed clarified.
What's the difference between the new ExtAuth and the old AuthPlugin system? Just a quick jist...
I'm unsure of one thing related to $wgSecretKey and shared users. Obviously a set of wiki using a shared user table and a shared cookie $wgSecretKey should be the same on all wiki. However, given a set of wiki using a shared user table, but not using a shared cookie (ie: potentially domain separated wiki like example.com and example.org) should $wgSecretKey be the same since the users are the same, or different since the cookies are different?
