Ok if database is fine then SSO itself is working.
What Mediawiki version are you using right now? I probably should try to upgrade my own instance to latest version and check if something will break.
If you have some understanding of PHP you can try debug it on your own:
- Make sure code for
Auth_remoteuseris in the end ofLocalSettings.php - Try to add something like
var_dump($SSO_STATUS);exit;and check what it’s going to print when you going to wiki. - SSO code working fine and there is valid username then make sure
Auth_remoteusermediawiki extension is in proper directory and working fine.
Also feel free to can contact me via instant messenger if you need some assistance. You’ll find contacts via my profile.
