When in Denmark this year (hello Ole!) I looked at pam_mkhomedir quite closely. The object was to automatically create home directories, not for Slurm users. What I found was that pam_mkhomedir uses a precompiled executable, rather than triggering a script which you would expect. So it is difficult to customise. there is an Oddjob based version https://access.redhat.com/discussions/903523 However in the past I have found the Oddjob version unreliable on an HPC cluster, so used the standard pam_mkhomedir pam_script does look to be the answer here. And I do admit to not having heard of it.
