This extension allows Mediawiki to authenticate against a remote Drupal 4.6/ 4.7 site.

The full GPL source is available at http://www.prattenplus.net/emu

==Overview==
Emu enables Mediawiki to make encrypted authentication requests over the internet to a remote Drupal Installation. You may customise the Drupal role that a person must have before being authenticated.

==Partial Source==
Here is the core of the extension from 0.91 version.
