See scheduling tutorial starting on page 27 http://slurm.schedmd.com/SUG14/sched_tutorial.pdf Smaller jobs tend to get preempted larger jobs.

I'm not sure what you're expecting here but FWIW we have this python script to sync slurmdbd users/accounts with one POSIX group (typically with LDAP backend through NSS): https://na01.safelinks.protection.outlook.com/?url=https%3a%2f%2fgithub.com%2fedf-hpc%2fslurm-llnl-misc-plugins%2fblob%2fmaster%2fsync-accounts%2fslurm-sync-accounts=01%7c01%7cwschulz%40email.unc.edu%7c401409cdd9da4e25582d08d3910c4bee%7c58b3d54f16c942d3af081fcabd095666%7c1=in2Qj%2fMuyvMG1xniKFGwKdGKVxGuE6NvSCN9ZYG2yIw%3d It's rather straight so you may tune easily it to fit your needs.
