We set up external authentication via SAML. If a contact is created in the portal power apps portal he can log in on our external portal (external identity is created) from there, a redirect is happening via return URL to the power apps portal.
However the user is not logged in on the power apps portal, but he should be. Do you know which settings I need to review in the portal to maybe solve the issue? Or is this something our client (who manages the external portal) needs to configure in terms of passed metadata?
the basic settings for configuring a SAML identify provider can be found here: Configure a SAML 2.0 provider for portals - Power Apps | Microsoft Docs
I am a bit confused with your issue
@OliverRodrigues Yes we got a custom registraton form on the power apps portal.
When the contact submits the form with username and passwort he is able to log-in on our external portal, after he loggs into the external portal a redirect happens to the power apps portal and then an error message appears with "invalid sign in attempt"
