When configuring RH SSO integration in the admin portal, it is sometimes desirable to configure it to automatically select a specific IDP on the RH SSO side. This is typically done by adding a query parameter to the login url. However, if you try to do this from 3scale, by adding it to the Realm field in the SSO integration form, it breaks the login URL and it does not work correctly. It would be helpful if we either handled this parameter properly or added a new form field for this.

See the RH SSO documentation for more details on this parameter. https://access.redhat.com/documentation/en-us/red_hat_single_sign-on/7.5/html/server_administration_guide/identity_broker#client_suggested_idp
