[slurm-users] Re: Slurm commands fail when run in Singularity container with the error "Invalid user for SlurmUser slurm, SINGULARITYENV_SLURM_CONF

In https://support.schedmd.com/show_bug.cgi?id=9282#c6 Tim mentioned this env variable SINGULARITYENV_SLURM_CONF, what is the usage/syntax for it? I can't find any reference to this. I'm running into the same issue mentioned there. Thanks in advance!
