Thanks a lot for your help!!. We understand AG a little better now :-)<br><br>Another question: we are trying to consume Venue and VenueServer web services without success. Now, I understand that as AccessGrid relies on Globus Toolkit (I have heard about it before, but I understand it better) we need to construct clients compatible with it. Using JAX-WS (used by Netbeans IDE) is not a good idea. Am I in the right way??<br>

First of all, thanks again for your help, I have several questions,
this time related to server certificates. Do the things we were talking
about identity certificates apply to server certificates?. We have a
developer who is working in consuming AG server web services from a
Java Client. He would like to work at home, but unfortunately our
request for opening certain tcp ports was denied because of security
issues. I told him to run server and client in his machine. I had to
make a server certificate request to be able to run the server first
time:<br>

The server does require a certificate; this requirement cannot be
avoided.<span class="q"><br>

You can build up the required certificate state completely independent
from the Access Grid Developers CA if you want. In that case, you'll
have to make sure that the CA cert is installed at both the server and
at client machines. And the CA cert will have to be used to sign the
certificate used to run the server. This is standard PKI practice, so
you should be able to find sufficient references online. If you have
trouble, please ask.<span class="q"><br>
<blockquote type="cite">- Is there a way of exporting a certificate from command

unexpectedly. I reported it and there is someone working to provide you
a better report) so I cannot do it through graphical interface.<br>

You can use certmgr.py. In some cases, it will be called certmgr3.py.
After running it, type 'help' for a list of available commands.<div><span class="e" id="q_118f1d389dac165e_7"><br>

Luis:<br>
<br>
There are a few things you need to know in this regard:<br>
<br>
- By default, AG3 venues do not require that clients have a certificate<br>
to enter. Venues can be optionally configured to require a certificate,<br>
in which case the user must present a certificate that satisfies the<br>
access controls on the venue.<br>
<br>
- You can run your own CA and issue your own certificates. In that<br>
case, you'll need to make sure your clients have both your CA<br>
certificate and their personal certificate.<br>
<br>
Otherwise, this is general PKI. If you have other questions, don't<br>
hesitate to ask.<br>
