Authorization for discourse from another site

After our users have logged into our site, I want to provide them with a link to discourse. They have already been authenticated and so I essentially want to do the second half of DiscourseConnect, by sending the user information to Discourse and having them logged in automatically there.

In this scenario, the login page provided by discourse would be redundant. The only way to reach the discourse community would be via our site.

Is this possible? Any pointers would be appreciated.
