Prior to the changes in SP5 trusted auth was still available https://apps.support.sap.com/sap/support/knowledge/preview/en/1795949
That KBA shows an older method where the SAML users are tied into the tomcat users then picked up by trusted auth.
Trusted auth is the logging in via username, so what you must be able to figure out is if you can deliver the user name (from your SAML) to any of the variables that trusted auth can pick up. This is not something that SAP documents, we generally pick things up form the point of tracing if the variable received a value (and what). Trusted auth was designed to be open to any type of authentication front end, but delivering the username to places such as http_header, web_session, etc can be a challenge.
