[MediaWiki-l] Sharing users and session across wikis im MW 1.27
I'd like to have a very simple solution to sharing user tables and session data between two mediawiki installations on the same webhost.
Feature 1: Users that log in into wiki B and already have user credentials in wiki A can use the same credentials (wiki A is the master, wiki B the "slave" wiki)
Feature 2: Users that are currently logged in into wiki A should be logged in in wiki B without additional login-procedure
Can someone show me a very simple example on how to do this in two MW 1.27.x installations on the same webhost? Wiki A in my example already exists. Now I want to setup wiki B (in a separate database, but on the same webhost) and would appreciate a simple way to do this.
