You are getting some good insights here. To add to them, there is a VERY
good chance that your pam.d setup needs tweaked. If a user authenticates
by something else before pam_slurm_adopt, then that is the access they
get, which means, no adoption into the job constraints.

Hi,
We have blocked ssh to nodes where users do not have a running job.
However, when there is a running job, a user can ssh to that node and
use more than the slurm resources allocated on that node. Am I missing
something?
I usually request an interactive session of 2GB. I then open another
terminal and ssh to the node where the interactive session runs. I
allocated a 4GB R variable on the node where I just ssh but this does
not error out.
Additionally, if I end my interactive session, the ssh connection
still lives which I believe should not happen.
Best,
