Now I can't log in to Confluence.
I tried deleting my Confluence Config file and starting over. That does reestablish the link to JIRA and I can log in with those accounts again.
BUT when I restore my Confluence data (probably the whole site) then I am not able to log in.
Unfortunately I don't know the root Confluence account or if there even is one since it was configured to use JIRA users from the get go. I can see a whole mess of local users from Windows AD in the backup file.
Thanks for any help.
