[slurm-users] New Bright Cluster Slurm issue for AD users

[Yugendra Guvvala]

No, we can’t ssh to compute nodes. And this is by design that no one should be able to ssh to compute nodes other than root. 

I figure that munge is not configured for AD. We have configured our login image for AD and slurm and mung configurations are on head node. Not sure how to integrate these. 

Thanks,
Yugi
