[slurm-users] salloc not working in configless setup on login machine

[Angelos Ching]

Hi Gizo,

I noticed SLURM_CONF was set to a broken socket when inside salloc, 
that's why sinfo was confused.
I've found a workaround that if I "unset SLURM_CONF" before sinfo, then 
sinfo works.

Maybe a bug needs to be reported for this.

Best regards,
Angelos
