Issue with SSO login when following a shared link

A user, Kevin_McKinney, reported an issue with SSO login when following a shared link from a topic. However, after codinghorror requested reproduction on a customer site, techAPJ was unable to reproduce the issue. Kevin_McKinney later realized that the issue was with their own hacked-together SSO provider site, which was redirecting incorrectly, and not with Discourse.

I’ve set up SSO for my Discourse instance at my company, so that users can log in with Windows authentication against our internal Active Directory. This has worked fine so far.

What I noticed today is that when I email a link to people which is a shared link from a topic I created, there are problems logging in if they followed that link.

Here are some relevant pieces of info:

Root URL: http://{computer_name}
Shared link: http://{computer_name}/t/expand-code-n-lines/278?u=kmckinney

When I click Login, my browser URL reflects this, but doesn’t log me in.

http://{computer_name}/t/expand-code-n-lines/278?u=kmckinney/session/sso_login?sso={sso_payload}

If I then go to the root URL for the site, I’m able to log in without a problem, and then I can follow the link and view the post as a logged in user.

Please let me know if there is more info that I should provide. Thanks!

@techapj can we repro this on a customer that uses SSO?

I realized what the issue was, and it is not an issue with Discourse. My hacked-together SSO provider site (so users could authenticate against our internal Active Directory) was redirecting incorrectly. :flushed:
