During SiteMinder new partnership configuration in admin UI, there was a RED text error pop up when trying to save the new partnership:
"You must select a HTTP-Redirect or SOAP Single Sign-On Service."
What causes this error?
SiteMinder: ALL version
The error is working by design.
SiteMinder as SP only supports HTTP-Redirect, SOAP during remote SSO. Within Remote SSO Service URLs, either deselect "HTTP-POST", or remove any HTTP-POST entry.
SiteMinder documentation states:
Documentation reference: SAML 2.0 Remote IdP Entity Configuration
