problem of thinking of ACE/ACL's and enforcement infrastructure, which i think
is rich for work. We do have to leverage Globus for our security, but I
know Globus has done some work on SASL integration. Has Passport done anything
to be a SASL option? If so, we could consider targeting
SASL abstracting the actual security implementation out of the
infrastructure (which might benefit everyone). I'll read up on SASL to
see if this makes more or less sense.</span></font></p>

style='font-size:10.0pt;font-family:Arial;color:navy'>Have you looked at the
WS-Security specification? It provides for attaching X.509 certificates
to SOAP messages and signing the messages. In reviewing the Globus
Toolkit 2.0’s security model, it seemed that WS-Security would be a great
way of using Globus certificates with web service calls. The “Web
Services Development Kit” has a preview implementation of WS-Security for
.NET You can download the <a
href="http://msdn.microsoft.com/downloads/default.asp?URL=/downloads/sample.asp?url=/MSDN-FILES/027/001/997/msdncompositedoc.xml">WSDK
Preview</a>. See <a

<p class=MsoNormal style='margin-left:.5in'><font size=2 color=navy face=Arial><span
style='font-size:10.0pt;font-family:Arial;color:navy'>Unfortunately, the WSDK
still doesn’t have ACL/ACE functionality for authorizing users’
access to objects. I’m prototyping a couple of classes that basically
mirror the ACL/ACE/group design from VMS/NT for an unrelated project if
you’re interested in collaborating in this area. The idea is to
have a generic “authorization” object that you can
“attach” to an object, set the ACL, serialize the ACL for easy
storage, and perform authorization checks.</span></font></p>

details on web service interfaces of SQL schema in the discussions.
I’d like to talk at this level so that we can get interoperability
going. I’ve done a first pass at SQL schema synchronization with
Shawn Davis and I think I should be AG Venue Server functionality compatible
with my next venue server release. I’d love to be in a position
where we (MSR) release a subset of functionality and both ANL and NCSA are able
to add on functionality to the same server by adding additional functionality
on top of the same data store.</span></font></p>
