Looking at git, it's a bit of both:

src/slurmd/slurmd/req.c:

         setenvf(&env, "SLURM_JOB_UID", "%u", job_env->uid);
[...]
         setenvf(&env, "SLURM_JOB_USER", "%s", job_env->user_name);

so the variables get set on the slurmd side (as you'd expect) but from 
data that is sent along with the job.

All the best,
Chris
