Due to some recent changes to Confluence’s ConfluenceCrowdSSOAuthenticator (which is used as part of Crowd SSO integration with Confluence) SU user sessions are being closed almost immediately as the ConfluenceCrowdSSOAuthenticator re-authenticates the session as the original user. The outcome is that Switching to a new User via SU has the appearance of navigating to the Dashboard page whilst remaining as the same user.
Environment
Confluence 7.13.20 +, 7.19.15, 8.5.2
Crowd
Replication
Create an instance of Confluence 7.13.20 and an instance of Crowd and configure Crowd SSO as per the following documentation:
With SSO configured and the ConfluenceCrowdSSOAuthenticator enabled in the seraph-config.xml file, install SU for Confluence and attempt to SU to any user.
