Hi there,
I use the following cron job that runs every night to add new users:
#!/bin/bash
function usersInGrp {
echo -n $(getent group "$*" | cut -d':' -f 4- | awk -F',' '$1=$1')
}
for user in $(usersInGrp 'cluster.users'; usersInGrp
'ALT_DOMAIN1+cluster.users'; usersInGrp 'ALT_DOMAIN2+cluster.users'?)
do
# Check for existing account.
if [ "$(sacctmgr -nP show user $user | awk -F'|' '{print $2}')" == "" ];
then
# User has no default account. Add one.
sacctmgr add user $user DefaultAccount=nullAccount
fi
done
There's also a relatively simple inverse script to remove users who are no
longer in the group.
Regards,
Sam

Subject: Re: [slurm-users] Accounting: Default Associations for Unknown Accounts
Yes, in a way. In thinking about this for Brown (we haven't implemented it,
yet), we've the idea of having a Linux cron job periodically query the group
membership of the AD group granted access to the HPC resource, and adding any
new users to the SLURM accounting database.
We're at the point of using AD for ssh/login authentication via sssd, but still
maintain an cluster/internal NIS database for pwent and cluster-specific group
info (i.e., only the login gateways do AD authentication). Our SLURM
associations are updated automatically when the NIS account is created or
modified (via webmin).

Hello,
we think about switch to SLURM. Currently we grant access to the cluster using
a active directory group, everyone in this group is allowed to run jobs.
So the users are not known to the SLURM accounting database.
Is it possible to automatically add every new user to an default account
without manually adding the user with "sacctmgr add user user123 Account=test".

Ulf
