=================================
Creating groups with the same uid
=================================

If the ``/projects`` folder resides on an NFSv3 volume and you have a setup
with several compute nodes, AEN will create local users with a different uid
on each node.

To make the AEN compute service create groups with the same uid:

#. In the ``/opt/wakari/wakari-compute/etc/wakari/wk-compute-launcher-config.json`` file, change the identicalGID key value to ``true``:

   .. code-block:: bash

      , "identicalGID": true

   If you don't see the identicalGID key, add it.

   NOTE: You must add the comma at the beginning of the line. If you add this
   line as the last key, you must remove any comma at the end of the line.

#. Restart the AEN compute service:

   .. code-block:: bash

      sudo service wakari-compute restart
