Hi all, 

I’d like to have all my users being able to SSH to the compute nodes when 
-nobody- has an active allocation on the node. I’d like to still use PAM access 
control to prevent users logging into compute nodes that are allocated through 
Slurm. 

I have made experiments with this and found easily how to make the pam module 
prevent non-allocated users access. 
However, users are also prevented to login at all time, even when no work is 
active on a node. 

The typical workload for this machine is mostly debugging/shared jobs, with 
(occasional) exclusive batch jobs. I can also appreciate advises on a more 
Slurmy workflow for that type of usage pattern. 

Best, 
Aurelien
