[wp-hackers] Wordpress SSO

[Malte Witt]

Thank's for your reply. I already thought about this and wanted to use 
SimpleSAMLphp (wordpress A would be the Identity Provider in that case).

There already is a plugin for this 
http://wordpress.org/extend/plugins/simplesamlphp-authentication/ but I 
didn't had a look at it yet.

Actually - as outlined in my previous mail - I'm already stuck before 
getting that far in the login process. ;-)
