Hello.
I have this error on the Jira datacenter version : Account already exists.
User with the email ( email adress) already exists. How do you vant to continue? Review profile / Add to existing account
and the user cannot log in. This is happening when a user is deactivated ( left the company and then rejoined) and the account has reactivated. I tried to delete the user ,unjoined from the the AD jira users group . I let 1 day to everything fully sync . After that i recreated the user ( rejoined in the AD specific jira user group ) and when the user wants to log in the error reapares . Can you help me with this error?
