DESCRIPTION

       daemons to allow authentication to the cluster. The program will run as the SlurmdUser. When  running  in
       Slurm's  "configless"  mode,  in  which  case  configuration  files  are  retrieved and written under the
       /run/slurm/conf directory.

OPTIONS

              Retrieve configs from slurmctld running at host[:port].  Requires slurmctld  support  provided  by

              Read configuration from the specified file.

       -h     Help; print a brief summary of command options.

       -v     Verbose mode. Multiple -v's increase verbosity.

ENVIRONMENT VARIABLES

       The following environment variables can be used to override settings compiled into sackd.

       ABORT_ON_FATAL
              When  a  fatal  error  is  detected,  use abort() instead of exit() to terminate the process. This
              allows backtraces to be captured without recompiling Slurm.

       SACKD_DEBUG
              Set debug level explicitly for syslog and stderr. Valid values are 0-9, or the same string  values
              as the debug options such as SlurmctldDebug in slurm.conf(5).

       SACKD_STDERR_DEBUG
              Set  debug  level  explicitly  for  stderr. Valid values are 0-9, or the same string values as the
              debug options such as SlurmctldDebug in slurm.conf(5).

       SACKD_SYSLOG_DEBUG
              Set debug level explicitly for syslog. Valid values are 0-9, or the  same  string  values  as  the
              debug options such as SlurmctldDebug in slurm.conf(5).

       SLURM_CONF
              The location of the Slurm configuration file.

       SLURM_DEBUG_FLAGS
              Specify debug flags for sackd to use. See DebugFlags in the slurm.conf(5) man page for a full list
              of flags. The environment variable takes precedence over the setting in the slurm.conf.
