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. ;-)
