https://dev-509262.oktapreview.com/home/ciscodev509262_qacloudidp_1/0oafomw1ckrET03ok0h7/alnfomxw5xKrbOOxn0h7

What is the corresponding URL in ADFS to login to a relying party directly

Answer 1

Assuming the Relying Party Trust is a SAML2 Service Provider, the URL to perform an IDP initiated sign-in you can use the following URL:

https://<URL ADFS FARM>/adfs/ls/idpinitiatedsignon.aspx?LoginToRP=<RPT Identifier>

Where URL ADFS FARM is the result of this command:

(Get-ADFSProperties).HostName

And where RPT Identifier is one of the identifier of the relyin party trust you want:

Get-ADFSRelyingPartyTrust | Format-Table Name,Identifier
