Incremental sync fails after authentication if default groups have been added to a Jira directory

XMLWordPrintable

      Symptoms

      The next incremental sync just after an authentication fails and produces an stacktrace in the logs:

      Steps to reproduce

      1. Set up a Remote Crowd directory/Jira Directory, configure it to automatically add users to a group on login.
      2. Sync the directory.
      3. In the remote Crowd server, create a user. Do not add him to the group.
      4. Authenticate as the new user in the client application. This causes the user and his memberships to be copied from the server. It also causes the user to be added to the default group in both the client application and the remote server.
      5. Sync the directory.

      Expected result

      Client and server are already in sync, the incremental sync should succeed without making any update.

      Actual outcome

      Incremental sync attempts to create the membership to the default group again. Since this membership already exists in the client, an exception is thrown and incremental sync fails.
