We manage this via our job_submit.lua script. At submission time the
script looks to see if they already have an account or not and if they
don't it adds them. To lower impact on the database we have it cache
the lookups.
I think the real concern is continually beating on the database. So you
want to cut that down by whatever means you think is reasonable.

Hello everyone! We have a script that queries our LDAP server for any
users that have an entitlement to use the cluster, and if they don't
already have an account on the cluster, one is created for them. In
addition, they need to be added to the Slurm database (in order to
track usage, FairShare, etc.).
I've been doing this manually with a command like this:
sacctmgr add user <username> Account=root DefaultAccount=root
I would like to add that command to the user creation script, but I'm
warned off by the Slurm docs that say never to call sacctmgr in a
script/loop. I understand the reasons why doing so multiple times in
rapid succession can be a bad idea. In our case, however, it would be
rare to have more than one new user at a time (our script runs in
15-min. intervals). Is there really a concern in a case like ours?
How do you all handle adding users to Slurm's DB? Manually? Or, if not
by script or some automated means...??
Warmest regards,
Jason
