-====== XMPP/Jabber authentication  ======
-===== Incompatibility with the current version of DokuWiki =====
-  * Tried to use both variants on DokuWiki version 2009-12-25c "Lemming". Both rendered my wiki inaccessible with "Bad user authentication configuration. Please inform your Wiki Admin."  --- //lolmaus 2010/02/17 18:58//
-===== What does it do? =====
-It authenticates users by logging into an XMPP server. This was originally conceived in order to have a website authenticate against email accounts set up on Gmail for a whole domain. It's really incomplete and "hacky."
-===== Requirements =====
-  * XMPPHP (http://code.google.com/p/xmpphp/)
-===== Installation =====
-Paste the code into "inc/auth/xmpp.php", then add the following line to "conf/local.php":
-  $conf['authtype'] = 'xmpp';
-And remember to alter "xmpp.php", so that it suits your configuration.

-===== Alternate Code =====
-The above doesn't work for me, I don't know if the way Doku works has changed since it was written as i'm a first time user (above doesn't use class). The code below 'works' for me, same warnings as above really its a total hack and has very minimal functionality YMMV.
