I was struggling like crazy with this one a while ago. Then I saw this in the slurm.conf man page:
AccountingStoragePass
The password used to gain access to the database to store the accounting
data. Only used for database type storage plugins, ignored otherwise. In the
case of
Slurm DBD (Database Daemon) with MUNGE authentication this can be
configured to use a MUNGE daemon specifically configured to provide
authentication between clus‐
ters while the default MUNGE daemon provides authentication
within a cluster. In that case, AccountingStoragePass should specify the named
port to be used for
communications with the alternate MUNGE daemon (e.g.
"/var/run/munge/global.socket.2"). The default value is NULL. Also see
DefaultStoragePass.
So in case you are using MUNGE, you leave this out in slurm.conf, because the
path to the socket is used as default. You specify the database password only
in slurmdbd.conf.
Cheers,
Barbara
