We are running 23.02.6 and have a partition with a specific account set in AllowAccounts. We test that only that account can use that partition, and it works. I'll note that you'll need to set EnforcePartLimits=ALL in slurm.conf for it to work, and if you use the job_submit filter, make sure you don't make changes there that change the account (we do that, that's why I mention it).

Subject: [slurm-users] AllowAccounts partition setting

At one point, when we were running slurm 22, we set up a few new partitions with `AllowAccounts` setting enabled. We limit access to these partitions only to a few accounts. We manually create these accounts and users using the `sacctmgr` command. At that time, everything was working. Only users in these accounts were able to run jobs in that partition. Few months ago we upgraded slurm to 23.02.7 but just a couple of days ago we noticed that anyone could submit jobs to these partitions. In addition to that, you can provide any value to the `--account` directive and slurm will accept and record it in the job accounting database. In our initial testing, you could only provide `--account` value that has been previously created.

I'm still looking into this but I wanted to check if there was any change in version 23 that could have impacted this? I don't remember seeing anything in release notes.
