I have configured Confluence to use SSO 2.0 with the SSO for atlassian server and data center plugin.
The SSO I am using is OIDC with Keycloak.
When I go to the confluence login page, I can see the Login with IdP button, and using it successfully routes me to Keycloak login page, then redirects me back to confluence.
The problem: If I go to a confluence site or page with additional query parameters
?spaceKey=ABC&title=123
the & will become URL encoded into & like so:
?spaceKey=ABC&title=123
And this results in a "Page cannot be found" error.
Any advice is appreciated, thank you!
