[slurm-users] Replacing MUNGE with SACK (auth/slurm)

Does SACK replace MUNGE? As in - MUNGE is not required when building Slurm or on compute?

If so, can the Requires and BuildRequires for munge be made optional on bcond_without_munge in the spec file?

Or is there a reason MUNGE must remain a hard require for Slurm?

Thanks,
