Include SSO with all links to Discourse?

I use WP as my base authentication and then SSO through Discourse. I have occasional issues where users click on a link to Discourse and aren’t logged into the forum automatically.

In my menu, I link to the forum like this: https://forum.umhoops.com/session/sso?return_path=https://forum.umhoops.com

And that (from what I understand) logs them in but at other places (I have a RSS list of topics displayed, for example) the links don’t automatically log them in. I was wondering if there was a good way to automatically log in users to the forum on other links?

Thanks
