We have multiple client's IDP federated with our ADFS 4.0 server.
A user click login from web application (RelyingParty ) then redirected to ADFS's IDP selection page and redirected to there respective IDP page.
Now my question is how to pass RelyingParty identifier("https://webapp.mycompany.net") to IDP.
I see wtrealm has the RPI but when ADFS redirects the request to IDP it changes the value to it's own identifier(http://sts.mycompany.net/adfs/services/trust)
Can some one please help me on this?.
