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'.
