The problem I’m running into is that when calling the `system.perspective.logout` function, I believe it is just logging out the user out of the current project.

So to give some context, I have 3 projects in question here and the user starts in the same order: projects 1, 2, and 3. 1 has no permissions so no need to authenticate. Then they navigate to project 2 and authenticate. Then they are passed to project 3 and the authentication from project 2 is passed over.

Now when call logout from project 3, then redirect them back to 1, then they go back to 2, the same user is still logged in.

Does `system.perspective.logout` just logout the user from the current project? And not any other projects?

Yes, and as I understand it, this is by design.  
There’s two separate ‘systems’ at play here - the IdP, and the Perspective session. system. **perspective**.logout only affects the Perspective session; your IdP session could still be valid. Many third party IdPs may not even allow external logout requests.

You could set Project 2 (and Project 3) to ‘Always Ask the IdP to reauthenticate’, in Project Properties → General:

From project 2 to 3, I don’t want the user to authenticate again. So I would enable this on project 2 only right?

So any time they access project 2 they are required to authenticate.

Sure, whatever you need for your requirements. You could also use `system.perspective.login` (instead of `logout`); there’s an optional `forceAuth` parameter that tries to force a login window when you switch. It might be harder to detect a transfer from 3 → 2 in that scenario, though.
