Problems with MW 1.13
I have problems after upgrading to MW 1.13 --Bajnokk 12:20, 30 August 2008 (UTC)
 * User.php requires a session_start at line 2111, if session hasn't been started. (I'm not sure, what goes wrong there)
 * SpecialUserlogin.php has been moved to specials/ directory
 * LoginForm->initUser requires a second (boolean) parameter, that's just a warning.
 * On a new user login (which should result in automatic account creation) I get the following error: . And indeed, User->mPassword is not set, nor are other fields (mNewpassword, mToken, etc). I can not circumvent that last one easily, so I'd appreciate your help.

I've made some changes to the extension to address the problems you described. Only about the session_start problem I don't know what's happening. --Stevel 14:19, 1 September 2008 (UTC)
 * Something is still wrong with automatic user creation. Now it tries to add the new user twice, the result is "Duplicate entry" (it seems that the users' session isn't started properly after creation and it tries to add him again)
 * About the first (session_start) problem: I still get a PHP fatal error after login I can only get through if I add an   there, but it clearly isn't the solution. Session should be started before, or maybe I have wrong configuration? It might be the cause of other problems as well, don't know. Thanks!


 * Fix for "Duplicate entry" error: capitalize the first char of the username in LocalSettings.php:

$shib_UN = ucfirst(strtolower($_SERVER['HTTP_EMAIL']));
 * The problem is that MW 1.13 does not capitalize that char automatically when saving the new user but when checking if user exists, sql query is made with capitalized first char and so MW tries to save new user with existing username.

= update for mediawiki 1.11 = (code deleted because not needed anymore) "return true;" added in function SSOLinkAdd

= Ammended patch file for MW 1.11.2 = Thanks(!) for Peter Jacobs for the patch. However it did not work for me out of the box. So I fixed the patch (BringBackAA function really) and am including patch instructions below:

Install Patch

 * 1) Create a file called ShibAuthPlugin.patch in your extensions folder.
 * 2) Copy and paste the code below into it.
 * 3) Make a backup of ShibAuthPlugin.php
 * 4) Patch the extension

cd extensions vi ShibAuthPlugin.patch \\ copy and paste code cp ShibAuthPlugin.php ShibAuthPlugin.php.bak patch ShibAuthPlugin.php ShibAuthPlugin.patch

If you need to reverse the patch, just type patch -R ShibAuthPlugin.php ShibAuthPlugin.patch
