[slurm-users] slurm: error: Security violation, ping RPC from uid 1000

[Alper Alimoglu]

Both my frontEnd and compute node has the same `UID` and `GID` but I am
having same error on [slurm uid and gid must be consistent across the
cluster <https://github.com/CSCfi/ansible-role-slurm/issues/11>]. How can I
fix this problem?

**My frontEnd:**

    $id
    uid=1000(alper) gid=1003(alper) groups=1003(alper),27(sudo),999(docker)

**My compute node:** (I have updated its gid it was 1001 before. I am not
sure whether slurm sees its updated version or not.)

    $id
    uid=1000(alper) gid=1003(alper) groups=1003(alper),4(adm),30(
dip),44(video),46(plugdev),1000(google-sudoers)
