We have two relying party endpoints that customers can configure in ADFS 3.0 for SAML 2.0 SSO.
When they click on both connections, they get taken to the "mylink" page. Is there something in the ADFS relying party field that cannot handle the "?redirect" syntax, so that it defaults to the "mylink" page?
In short, SAML 2.0 specification doesn't support redirect url like that. IdP (ADFS in this case) always returns the consumer endpoint which is /mylink in your case. A common trick is to use relaystate. You can set the relaystate attribute to the url you want to return after login, e.g. /mylink?redirect=differentpage. Please note that you will need to write code to do that redirection yourself after your application receives response from ADFS and finishes processing it.
