I'm running a cluster in Ubuntu generated by AWS ParallelCluster. When I run the cluster as the default user "ubuntu" with uid:gid 1000:1000, the cluster calls to a license manager on a separate server and registers the user by assigning a seat respectively with the format ubuntu@hostname.
To allow multiple users, I wanted to have each user with their own logins and call the cluster individually. As such, I have generated a second user with adduser newuser and then sudo usermod -aG sudo newuser, as the user requires sudo privileges to call the cluster program.
When I check the /etc/passwd I can see this user has been added with uid:gid 1001:1001, which I expect, and is part of the sudo group. However, now when I run the cluster process, my license manager registers the user as 1001:hostname instead of newuser:hostname.
Is there a setting I haven't amended that maps the username to external services instead of the uid?
