He can't use supper for the same reason he can't use rdist.
There's no magic answer to this. You've either got to make a common set of
accounts on all three systems or use something like NIS, LDAP, or a single
sign on product.
This is going off Paul's topic, but I've always wondered why IBM chose to
use supper in it's PSSP environment.
The only difference between supper and rdist that I'm aware of is that
rdist is a push technology where as supper is a pull technology (and maybe
the answer is a simple as that).
rdist comes as part of the base OS on every flavor of UNIX that I've worked
with but supper is always a separate install. Not a big deal but chances
are that an admin coming from a different environment to an SP system is
going to know more about rdist than supper.
Other than the push/pull differences is anybody aware of any other major
differences between the two products?
