Diagnosis

Enable SQL TRACE logging to check on the report of individual SQL requests that are sent to the database by Hibernate and you'll see the result for 'external_id':

TRACE [http-8443-18] [sf.hibernate.type.StringType] nullSafeSet binding '�򹄮��@���򹄮�' to parameter: 14

Cause

It's a known issue for Novell Directory Services as reported hereIt's caused by a character that is not supported in the user's GUID. WebSphere is known to have this problem too.

Resolution

Consult your System Admin to remove the invalid character from LDAP. Refer to this documentation as a hint to change the user's GUID.

If you are not able to change the GUID, alternatively you can re-create the user object in the Novell Directory Services that Confluence instance uses. This was possible as it is a read-only directory that obtains its data from a master directory.

tip/resting Created with Sketch.

The suggested changes are not supported by Atlassian, please consult your System Admin for the execution.
