I'm not sure what you mean by that statement. The orted passes its environment to its children; so whatever the slurm stepd set in the environment for the orted, the children should be getting.
Clearly, something is different here -- maybe we do have a bug -- but as you stated below, why does it work for me? Is SLURM 2.2.x the difference? I don't know.

Yes; see Ralph's prior mail about direct srun support in Open MPI 1.5.x. You lose some functionality / features that way, though.
