Tenable.sc SAML authentication with RSA Cloud

I'm trying to configure Tenable.sc to authenticate with RSA Cloud Authentication Service using SAML. These are new installations of both Tenable.sc and RSA Cloud, and this is my first attempt ever to configure SAML.

 

I've contacted both Tenable and RSA for help, and tech support is willing to explain their own products, but won't help with integrating the two. Can anyone provide instructions on how these two are supposed to be configured?

 

I've tried configuring RSA for both IDP- and SP-initiated. I exported the XML configuration files from RSA and imported them into Tenable.sc.

 

When I use the IDP configuration, I see the Tenable.sc icon in the RSA WebPortal, but when I click on it, a new browser tab opens with the RSA WebPortal; it doesn't appear to connect to Tenable.sc (that might happen in the background without my realizing it).

 

When I use the SP configuration, I browse to the Tenable.sc logon and click the button Sign In Using Identity Provider. That redirects me to the RSA WebPortal, where I can sign in. I'm then stuck in the RSA WebPortal rather than being signed into Tenable.sc.

 

Rather than using an XML file to move the settings from RSA to Tenable.sc, I could enter the information manually in Tenable.sc, but it's asking for Single Sign-on Service and Single Logout Service, and I don't know what to put in those fields.
