Hallo everyone

we have recently noticed that when running nodes in configless and dynamic mode, pam_slurm_adopt does not work properly, denying ssh access when the user has a running job. We traced down the issue to the fact that the dynamic nodes are registered with FQDN (e.g. c01.psi.ch), while pam_slurm_adopt uses this routine (https://github.com/SchedMD/slurm/blob/master/src/common/stepd_api.c#L181) to guess the stepd hostname, using the host short name (so, c01). If we use gethostname instead of gethostname_short then it works again. Has anybody experience with this, and is there a way to have dynamic configless nodes registering with the short hostname?

Thanks!

cheers
