Confluence user synchronisation create duplicated user account after user rename in the remote repository

    XMLWordPrintable

    Details

      Description

      Here are the step to reproduce:

      1. Set up an LDAP connector with Crowd and create an application with this user directory.
      2. Set up the Crowd user directory on Confluence with the incremental synchronisation option check.
      3. Once all the synchronisation is done.
      4. Change one of the user name on the LDAP repository.
      5. Wait a couple hours so that the Crowd is synchronise the change and Confluence also perform the incremental synchronisation.
      6. Restart Confluence, so that a full synchronisation will be triggered, but it is failed with the following error message:

        And the output from the database shows that there are duplication user with the same external ID but a different user name on Confluence but not on Crowd:

        (2 rows)
        

        So it seems that the incremental synchronisation is creating a duplicated user based on the user name instead of the external ID.
