Group and user permissions for NFS#

To install AEN with multiple compute nodes and a /projects folder on an NFSv3 volume, manually pre-create both the anonymous user and the $AEN_SRVC_ACCOUNT user on all nodes. Each of these users must have the same user identity number (UID) and group identity number (GID) on all nodes.

By default AEN creates local users with a different GID on each node. To make the AEN compute service create groups with the same GID:

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