I gave a .Net desktop application that can successfully authenticate using either the web-server oAuth authentication flow or the username password oAuth flow and I have it working using SAML in a Federated SSO environment.

I now have to get it working in a Delegated SSO environement. I can obtain a token from the client's token generator. But it is not clear how I can sign in and exchange that for the token that I need to use in the REST API calls. 
Anyone know how to do this?
