I believe that Slurm creates users in the database using the primary UNIX
group name. Slurm would not know about any secondary UNIX groups.
There must be a uniform user and group name space (including UIDs and
GIDs) across the cluster. It is your own responsibility to configure
users and groups in the passwd and group databases consistently, see
https://slurm.schedmd.com/quickstart_admin.html (search for GIDs).
FWIW, I have some information about creation of users and groups in this
Wiki page:
