single node Slurm machine, munge authentication problem

I'm in the process of setting up a singe-node Slurm workstation machine and I believe I followed the process closely and everything is working just fine. *See* below: **sudo systemctl restart slurmdbd && sudo systemctl status slurmdbd**

If needed, I can attach the results for the corresponding journalctl, but no error is shown other than these two messages slurmd.service: Referenced but unset environment variable evaluates to an empty string: SLURMD_OPTIONS and slurmdbd: Not running as root. Can't drop supplementary groups in the journalctl -fu slurmd and in the journalctl -fu slurmdbd, respectively. For some reason, however, I'm unable to run sinfo in a new tab even after setting the link the *slurm.conf* in my *.bashrc*... this is what I'm prompted with > sinfo: error: Couldn't find the specified plugin name for auth/munge > looking at all files sinfo: error: cannot find auth plugin for > auth/munge sinfo: error: cannot create auth context for auth/munge > sinfo: fatal: failed to initialize auth plugin which seems to depend on munge but I'm cannot really understand to what specifically — it is my first time installing Slurm. Any help is much appreciated, thanks in advance!
