I would say no, it's not sufficient. While this will work with your
machine and internal organizational unit (OU) it will not work with the
rest of the AG2 community. That's because your cert will have been
signed by the CA with O=Foo Bar/OU=foo.bar.com/CN=ca.foo.bar.com

Now on your AG node this might be fine, but now on your node you will
only accept certs that have been signed by globus.org (since that comes
with globus) and your CA. If someone from outside comes in with an
O=Access Grid/OU=agdev-ca.mcs.anl.gov/ signed cert, they'll be denied
because your node doesn't recognize that as a validly signed cert (since
it's not from globus and not from foo.bar).

Now, if you try and take your personal foo.bar signed cert to someone
else's node (or venue for that matter), you'll get denied because that
resource won't recognize foo.bar as a validly signed cert.

What you *really* wanted to do was add your CA to your trusted certs
list. That way you'll accept your certs, globus certs, and agdev certs.
All you have to do there is:

${GPT_LOCATION}/sbin/globus-build -install-only

sed -e 's,globus-sh-tools-vars.sh,globus-sh-tools.sh,g' <
${GLOBUS_LOCATION}/setup/globus/setup-ssl-utils.8dd8e752 >
mv -f ${GLOBUS_LOCATION}/setup/globus/setup-ssl-utils.8dd8e752.sed
chmod 0755 ${GLOBUS_LOCATION}/setup/globus/setup-ssl-utils.8dd8e752


That will install you CA's cert and make everything happy. You might not
have to do the sed stuff in the middle though I found recently installed
simple_ca assume they're installing into gt2.2 and this doesn't work for
our gt2.0 installations (don't even get me started on this)...

Did that make sense?
