- Users appear twice in the People Directory, in shares, and mentions
- Users have two USERINFO records with no 'prevver' value (ie two current records), eg:
USERINFO records that do not have an entry in prevver are the currently active records. This is a little counter-intuitive given the name of the field, however older records that are no longer active contain the id of the superseding record in prevver. If prevver is null, the record is considered active.
This may not be the only way to have this happen, but doing the following sequence will cause this to happen:
- Create a user in an LDAP server, which you want to test with
- Set up the LDAP server in Confluence
- Log in as that user and possibly add some extra profile information such as a picture/description
- Disable the LDAP directory
- Rename that user in the LDAP server
- Create a new LDAP directory exactly the same
This has been confirmed to occur on upgrade to 5.1.3, and possibly earlier or later versions.
- These 3 users were duplicated as part of the upgrade to 5.1.3 (some irrelevant columns have been removed for ease of reading):

NB: Note the casing above - the 1st and 3rd records were originally uppercase, the second was originally lowercase.
- All 3 duplicates were created on June 7th. This was in the logs:
- I originally suspected that the casing of the usernames may have changed, but the users are currently in the original casing in cwd_user (upperfor USER1 and USER3, and lower for user2).
- There was a warning regarding a case change for user2, going back as far as October 2012 (found in old support case) :
- All 3 users are LDAP user accounts. This is a Delegated Authentication directory, and not a synchronising Connector type.
First, try a content reindex. If this doesn't help, run this query (on any version). If it returns any results, this bug is the cause of your duplicates.
If this query returns nothing, have a look at
CONF-36018 as well.
- Stop Confluence
- Make a full database and file system backup
- Run this command to find the usernames of affected users - ensure these match what you are seeing in the People Directory before deleting
- Run this command to delete the duplicate entries (all versions). The row with the higher contentid will be deleted.
- Restart Confluence.
- If you are still experiencing problems, have a look at
NB: If you have any trouble running the delete query because of foreign key constraints on the ATTACHMENT or CONTENT tables, do not remove the entries from that table. Instead, please get in touch with Support and we can help you remove the duplicates, and update the queries to be more robust.
