Description
It is possible for duplicate entries to exist in HipChat Server's crowd database tables, leading to failed synchronizations with external user directories.
Environment
- HipChat Server v1.3.4 or v1.3.7
- Configured to synchronize with an external user directory (LDAP, Crowd, Active Directory, etc.)
Steps to Reproduce
The steps to reproduce the root cause of this behavior are not currently known.
Expected Results
Synchronization with external user directory is successful.
Actual Results
Synchronization with the external directory fails, as reflected at Server admin >> Directory.
