According to the replies I've received, my plan A should have
worked. Going thru it again I found out that the problem
was I symlink'ed the /var/yp/binding/domain directory on the
slave server that came up but not on the test client machine.
I tried it again on the Solaris client (changing the /etc/defaultdomain
and rename the /var/yp/binding/domain) and rebooted. It's working
fine. One reply said it should have worked even without the
rename in binding directory, it didn't for me though. I still
have to try a SunOS box to be sure before converting
everything but it should work.
