Hi all, Unsure if this is actually a bug or a coincidental sideeffect, but I've noticed today (while testing an authentication plugin) that my login page remained in a loop. Situation: CASAuth.php added and activated. A request from a non-logged in user to a random page results in an authorization request that correctly defers to CAS. User logs in in CAS and CAS redirects back to MediaWiki which shows the correct new username. So far so good. Now, the user decides to logout using the link in the upper right corner (http://myserver/mediawiki/index.php?title=Speciaal:Afmelden <http://myserver/mediawiki/index.php?title=Speciaal:Afmelden&returnto=Hoofdp agina> &returnto=Hoofdpagina) <-- localized, translates to title=Special:Userlogout&returnto=MainPage A login required page is displayed that in it contains a link to log in again. However, this link apparently takes the current page's title as opposed to the returnto field resulting in a logON link of: http://myserver/mediawiki/index.php?title=Speciaal:Aanmelden <http://myserver/mediawiki/index.php?title=Speciaal:Aanmelden&returnto=Speci aal%3AAfmelden> &returnto=Speciaal%3AAfmelden (title=Special:Userlogin&returnto=Special:Userlogout). One can see, a login is immediately logged out again, resulting in a loop. The loop can be broken by /not/ using the login link provided in the loginreq page but by first selecting a random page such as MainPage, changing the inline login link to title=Special:Userlogin&returnto=MainPage The login link in the upper right corner seems to display the same behaviour. My system is MediaWiki 1.15.4 with a HiddenNamespace patch, a (currently commented out) CAS plugin found on (http://kellinwood.blogspot.com/2009/01/casify-mediawiki-with-phpcas.html) and now active Extension:CASAuthentication. This behaviour does not seem intended and is not desired. How can I change this? Met vriendelijke groet, Christian C. Schouten
