[slurm-users] Munge decode failing on new node

[dean.w.schulze at gmail.com]

There is a third user account on all machines in the cluster that is the
user account for using the cluster.  That account has uid 1000 on all four
worker nodes, but on the controller it is 1001.  So that is probably why the
question marks.

I doubt this is the issue when 3 of the 4 nodes that work have the same uid
mismatch for that user (nor the slurm or munge user).

What does this say on the controller and the compute node?

getent passwd 1000

Are you using LDAP or the like to ensure that all nodes have the same user
database?

All the best,
