I tried to google around, but could not get a clear view of how user
permissions are passed around with SLURM.
It would appear that your user accounts and home file system are not set
up correctly on all nodes. Sanity is required in order for Slurm to
work ;-)
First, ignore your Slurm setup and try to log in manually to all compute
and login nodes as user "username" and make sure this user (and all
other normal users in /etc/passwd) have the correct UID, GID and a
shared home directory file system mounted with correct permissions. I
find it a bit unusual if users have a home directory located in
`/usr/home/username'.
