How to Authenticate IONIC Mobile App using ADFS and SAML


We have developed a Mobile App using Ionic Framework. Now, we have the .APK file to be shared to users.

But, not all of our users have a Gmail/FB account, so we are unable to use OAuth. We have to use ADFS 3.0 with SAML2.0/WS-F.

Now, with ADFS you have to add your app as a Trusted Relying Partner, but after the .APK file, we don’t have the URL of the app. How to register it as a Trusted Relying Party

Secondly, how to send a SAML Request from an Ionic Application. Kindly, guide me on this.
