Hi Loris,
I don't know if this would solve your problem, but I think that node SSH
keys should be gathered and distributed. See my notes in
https://wiki.fysik.dtu.dk/niflheim/SLURM#ssh-keys-for-password-less-access-to-cluster-nodes

Hi,
We have set up pam_slurm_adopt using the official Slurm documentation
and Ole's information on the subject. It works for a user who has SSH
keys set up, albeit the passphrase is needed:
$ salloc --partition=gpu --gres=gpu:1 --qos=hiprio --ntasks=1
--time=00:30:00 --mem=100
salloc: Granted job allocation 7202461
salloc: Waiting for resource configuration
salloc: Nodes g003 are ready for job
$ ssh g003
Warning: Permanently added 'g003' (ECDSA) to the list of known hosts.
Enter passphrase for key '/home/loris/.ssh/id_rsa':

Authentication failed.
If SSH keys are not set up, then the user is asked for a password:
$ squeue --me
JOBID PARTITION NAME USER ST TIME NODES
NODELIST(REASON)
7201647 main test_job nokeylee R 3:45:24 1 c005
7201646 main test_job nokeylee R 3:46:09 1 c005
$ ssh c005
Warning: Permanently added 'c005' (ECDSA) to the list of known hosts.
nokeylee@c005's password:
My assumption was that a user should be able to log into a node on which
that person has a running job without any further ado, i.e. without the
necessity to set up anything else or to enter any credentials.
Is this assumption correct?
If so, how can I best debug what I have done wrong?
