ypset not allowed?

[Gregory N. Bond]

We have just updated to SunOs 4.0.3, and have come across some problems
with YP.  I presume it has to do with the increased security of YP in this
release.  I have not installed the "Security" install stuff, so we don't
use authenticated RPC etc etc.  Our YP master is a 3.5 machine.

When I try to run ypset (which we need to do, as clients have a habit of
binding to machines on the other end of a MAC bridge, overloading the link
in the middle), I get an error message:

  Sorry, I couldn't send my rpc message to ypbind on host wran.

from ypset and a message on the console:

  ypbind: Set domain request to host 192.9.200.50, from host 192.9.200.63,
  failed (ypset not allowed)!  

How do I do a ypset?  I currently have to kill the ypbind and restart it
and hope this it binds on the right side of the MAC bridge...

Have I installed something wrong?  Is thes a Known Bug?
