Any way to force login popup to open by url query string?

I’ve got a similar question. Although not to display the login popup, but to log the user in via our SSO provider if there is a login query string parameter.

  • We use our own system as the SSO provider to Discourse.
  • We have a mixture of public and private pages on our Discourse, so we don’t have login_required set.
  • If a user authenticates in to our system, and we link them to our Discourse root url, they are shown the public categories but are not logged in.
  • If a user authenticates in to our system, and we link them to our Discourse + /login, they are logged in fine, and redirected to the root Discourse URL.
  • If a user authenticates in to our system, and we link them to the URL of a private category/topic in Discourse, they are shown a page asking them to login. If they click Login, they are automatically logged in and shown the category/topic.

This last case is the problematic one. I think one of the following would be good:

  • we can link to ourdiscourse dot com/c/some-category?login=true and an auth check is performed - if user is logged in, show them the topic. If not, send them to our SSO provider, and redirect them back to the topic after logging in.
  • we can link to ourdiscourse dot com/login?redirect=c/some-category and an auth check is performed - if successful, redirect to the page on the query string, if not, redirect to SSO provider, and redirect to the page on the query string after successful authentication
  • we can link to ourdiscourse dot com/c/some-category, and if it’s a private page, Discourse performs an auth check, which if successful takes you to the category; if not successful, redirects to SSO provider, then redirects back.

Thanks!
