Symptoms

JIRA keeps deleted LDAP users in the system as disabled users if they have created content. When the audit log is enabled, each time a synchronisation occurs, a new "delete" entry appears in the audit log for users that have been kept disabled this way. No actual change has been made on this user.

Steps to Reproduce

1. Link up JIRA to an LDAP directory
2. Create a user in the LDAP directory that has access to JIRA
3. Log in as that user, create some content
4. Delete the user from the LDAP directory
5. Synchronise the directory
6. Synchronise it again and see the delete entry re-appears

Workaround

1. Add the user back in the LDAP directory
2. Make sure the user has no groups that give them access to JIRA, so that it doesn't use up a license
