Slurm works with a "Associations", see some information in
https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_accounting/#associations

Under each account in the hierarchy you must define the different users 
that you want.  They must have different associations (under the same 
account), and you can give them different limits.  See this nice tutorial: 
https://slurm.schedmd.com/slurm_ug_2012/SUG_Oct2012_DBD.pdf

You can only put limits on future jobs, not on past and running jobs.  If 
you want to make limits for all of history, you need to setup "banking",
