Hi socaltester
I can't help per se (as I've never had to configure a SAML Auth connection) but perhaps the following idea might help you find a way.
SAML authentication is quite similar to OAuth2 inasmuch that they have the same (equivalent) basic concepts in regards to the back and forth between the client/AuthServer/ResourceServer to obtain the required access/bearer tokens(OAuth) / SAML assertions (SAML Auth).
It's likely a bit of trial and error - but in the absence of any other ideas and a default SAML auth connection profile within ReadyAPI!, perhaps you could tailor one of the default OAuth v2 auth profiles considering they have equivalent concepts?

AlumniHi socaltester,
Do you have a sample of the successful request which you need to send to your service?
Here: https://techdocs.broadcom.com/content/broadcom/techdocs/us/en/ca-enterprise-software/layer7-api-management/api-gateway/9-0/policy-assertions/assertion-palette/xml-security-assertions/create-saml-token-assertion.html I found an example of a SAML assertion.
