I'm trying to make a Client portal (IdP) in PHP.
That portal links to several SP's (like Magento, Google Analytics and Wordpress)
Seeing how this needs to works my IdP needs to initiate authentication. when clicked on a link to an SP the authentication needs to start.
So it needs an IdP first application. I try to set it up with SimpleSAML, the only problem is the initial explanation on the simpleSAML website isn't clear enough for me (https://simplesamlphp.org/docs/stable/simplesamlphp-idp) can someone give me some better or in depth explanation about IdP first?
this is a new client portal but the clients already have accounts with the mentioned sites and other sites, sometimes more than 1 account. Is it possible to connect those accounts without doing it myself but let the clients connect them?
If there are better solutions than SAML to this problem please don't hesitate to mention them
