Missing ReturnTo parameter when using with Shopware / Zend Framework

[aWuttig]

Hey Guys,

i try to write an Shopware Plugin which provides SSO against different Platforms like Facebook, LinkedIn etc. Unfortunately i get stuck since 2 days into a problem with your session handling.

I call this 2 lines inside my controller action:

$linkedIn = new \SimpleSAML_Auth_Simple('linkedin');
$linkedIn->requireAuth();

When i execute this, something went wrong with the session inside SimpleSamlAuth, because on some time the ReturnTo parameter is not there anymore and i will get an exception:

Bad request received
There is an error in the request to this page. The reason was: Missing ReturnTo parameter.

I think the problem is the shopware system which uses Enlight a Fork from ZendFramework. I recognized that when i put the auth code to a part before the ZendFramework Sessions gets initialized it all works fine!

Is there a best practice how i should configure the session handling for SimpleSamlPhp?

I'm sorry nobody ever answered to this, but this isn't really a suitable place for support questions. We have mailing lists for that.
Anyway, if you still need to know about integrating SimpleSAMLphp with your application, please read this https://simplesamlphp.org/docs/stable/simplesamlphp-sp#section_6 and send questions https://simplesamlphp.org/lists
