We have 7 machines running 1.3_ALPHA (haven't had time to upgrade to 1.3
yet) and just yesterday we noticed the following problem.

On one particular machine, when you attempt to run rcp to get a file
from any other machine, the following message is displayed:

   rcp: rcp: rshrcmd: setuid(118): Operation not permitted

(rcp'ing *to* another machine works just fine).

One of the few differences between this machine and the others (on which
rcp works just fine) is the following entry in /etc/passwd:

   +auser:*:0:0::/n/disk/1/auser:/bin/tcsh

This is just prior to the normal

   +:*:0:0:::

that calls in all the user info from NIS. Now it just happens that the
uid of "auser" is 118. Not only that, but when I move the "+auser" line
out of the way, rcp works just fine.

Does this problem sound familiar to anyone? Would a ktrace of the rcp help?
(I did one, but didn't want to waste list bandwidth with it).
