Symptoms

One or several users have multiple entries in the People Directory. Duplicated users are not shown in @mentions or shares.

Diagnosis and Resolutions

There are two possible causes for this - either a corrupt search index, or duplicated entries in the database.

1. A corrupted search index. Rebuild the index from Administration > Content Indexing. If that fails, try rebuilding the index from scratch. NB: If you use Atlassian Cloud, you may need to contact Support to perform the reindex, as per CONF-33400 - Getting issue details... STATUS .

2. You may be experiencing a bug that causes duplicate data in the database. Please follow the workarounds in the bug reports below to resolve the issue.
