Yes, that is part of it.  Ownership/permissions of a collection of files
used by 'sshd' is highly scrutinized.  And, as you've found out, it's
not a one-step task to switch the service over from running as
SYSTEM (or 'sshd_server').  There are a number of files that get created
the first time 'sshd' runs (or when it's configured with
'/bin/ssh-host-config') that need to be adjusted if you change the user
that runs the service.  You can find the full list of files in
'/bin/ssh-host-config' but at least a partial list is:

   /etc/ssh*
   /var/empty
   /var/log/lastlog
   /var/log/sshd.log

Make sure these are all owned by the user that's now running 'sshd'.
That should help.  If not, take a look at '/bin/ssh-host-config' for
files I've missed.
