Hi Andy,

We have RHEL7, and pam_slurm_adopt is working for us as well, with memory constraint working

auth       required     pam_sepermit.so
auth       substack     password-auth

account    required     pam_nologin.so
account    include      password-auth
# Ensure that users can only login if they have a job on the node
