2012-10-16 15:56:27,899 http-8080-3 WARN anonymous 956x149634x1 ba6xq2 141.192.133.82,127.0.0.1 /rest/gadget/1.0/login [atlassian.crowd.directory.DelegatedAuthenticationDirectory] remote username [ XXXX ] casing differs from local username [ xxxx ]. User details will be kept updated, but the username cannot be updatedDiagnosis
Check the username of the problematic user in LDAP. It will be stored with mixed case or upper case. However, in JIRA the username will appear in all lowercase.
Cause
This is caused by a bug within JIRA as tracked in JRASERVER-29025 - Mixed case usernames breaks the connection between JIRA and LDAP for User Management. As listed there it has been fixed in JIRA 6.0.
Solution
Resolution
Upgrading JIRA to the latest version will fix this bug. If this is not an option, the User Directory will need to be recreated to correct the username casing.
