We had the jira and confluence servers running before (both within the same server and using https scheme). Since the instances were old, so we considered upgrading, but using a different server to host the JIRA instance. Confluence was using the JIRA userbase and so the authentication was done using JIRA.
Now I am unable to login in to Confluence anymore (not even admin account). One of the user was using Remember me check and so he can still use confluence but no one else.
Please help us out with the issue, on how to add authentication. I read and tried different forums, but nothing applied.
