SSO into an APM session
Is it possible to SSO into an APM session?
My use case is this: We have an intranet set based off of Atlassian Confluence, which authenticates to Atlassian Crowd. Crowd will then pull in the user directory from LDAP. We would like to create a "SSO" portal for our users where they can go and click on any of their applications to be automatically signed into them. I am good with how to set up and configure the SSO portal itself, but the challenge I am trying to solve and having trouble with, is if I have an authenticated user already signed into Confluence, how can I put a link on Confluence, or an iFrame, such that when clicked on it will automatically sign in the user to the SSO/APM portal.
To the best of my knowledge, Confluence interfaces with Crowd via HTTP auth and hands back the user client a cookie. I am not 100% certain on that yet though. Im mostly interested in my options for allowing a user to SSO into an APM with credentials that have already been challenged by Confluence/Crowd and how that looks.
