Why would you allow submitting as another user anyway (unless you are
root, but then you don't need this anyway)?

Tearing out user validation is stupid, but I don't really see why you
would need this. Pretty much any grid should have consistent user ID
across the machines (unless you configure them manually), therefore the
need for /etc/hosts.equiv should be irrelevant.

If you are submitting into a grind from outside of the grid and there is
no way for ssh access, you are definitely going to use some sort of a
gateway, that will submit the job for you.
