This knowledge base article documents a frequently asked question:
"Is it possible to monitor URLs which use SSO authentication using the url_response probe?"
Component : UIM - URL_RESPONSE
Unfortunately, the url_response probe does not support SSO operations.
Potential workaround - Use the E2E probe:
e2e_appmon (E2E Application Response Monitoring)
e2e_appmon (E2E Application Response Monitoring) Release Notes
There is now fields in MCS for url_response probe for SAML/SSO. This is not used for redirects, it is used for monitoring the SAML/SSO certificates for expiration and other SAML/SSO monitoring.
