We have Jira/Confluence setup to use our LDAP server as the authentication server, using the user principal name as the name attribute and the object filter
(&(objectCategory=Person)(sAMAccountName=*)(memberOf=cn=atlass_company,ou=company,ou=company,dc=company,dc=local))
which allows us to login to our Atlassian products using our email address and domain password.
Due to some internal shuffling in our company, we have had to change the email addresses and subsequently the user principal names of a couple of our staff members. This has caused duplicate users to be created using the new UPN and email addresses, which means that we have exceeded our licence cap as well as all of the content created by those users is tied to an obsolete account.
Is there any way for us to merge these accounts, or to delete the old accounts that are no longer used?
