That will work.  You need to configure the pam_slurm_adopt module to 
control access, see
https://wiki.fysik.dtu.dk/niflheim/Slurm_configuration#pam-module-restrictions

SSH authentication must of course be configured in order for users to ssh 
to the nodes, but I don't believe that PAM cares about that.
