> > functional
> > interface (like BES)...
> >
> > (b)
> > ...because we want to find out if there is any important service

> > context that is not capable of using SOAP (over SSL layer)...
> >
> >
> > (c)
> > ... in order to find out if we can agree on SOAP/HTTPS or to
> understand> requirements from other non WS-based interfaces in PGI.

> >
> > Therefore the aim of this thread is to get to an agreement in
> this context,
> > while considering Attribute authorities like VOMS as a
> supportive service

> > ### Contacting functional implementations with SOAP
> >
> > If we consider the case that we communicate with an functional
> interface> like OGSA-BES - we agree on SOAP.

> > ### TLS/SSL Layer:
> >
> > # <strawman>
> > Foundational: Conveying identity for authentication.
> > SOAP over HTTPS (PGI_HTTPS). SOAP-over-HTTP communication using
> a SSL/TLS
> > transport protocol in which endpoints are mutually authenticated
> by X.509
> > end-entity public key certificates (PKCs).
> > # </strawman>
> >
> >
> > # <simple plumbings: authentication>
> > We use authentication either based on identities inside X.509
> end-entity
> > public key certificates or X.509 proxies (including
> restrictions, encoding
> > handled separately in another thread).
> >
> > This refers of using either one or the other of these
> certificate types on
> > the SSL/TLS level.
> >
> > For simplification of the profile - there should be no direct
> dependencies> with attribute-transport used for authorization.
> > # </plumbings>
> >
> >
> > ### Possible scenarios:
> >
> > # A. TLS with end-entity certificate, SOAP in message -> authN
> check with
> > CA
> >
> > # B. TLS with (restricted) proxy certificates, SOAP in message -
> > authN
> > check with proxy signer chain
> >
> > ### Possible Conclusion:
> >
> > # We use SOAP inside a message to contact functional interfaces.
> >
> > # We use either full X.509 end-entity certificates OR X.509
> proxies (with
> > restrictions)
> >
> > ### Open Questions:
> >
> >
> > Q: There are WS interfaces for functional specifications that
> matter to PGI
> > (BES, WS-DAIS and SRM) - so in the context of PGI - can we agree
> on SOAP
> > based on HTTPS as mentioned above?
> >
> > Q: If not - are there any important functional interfaces
> (except support
> > interfaces from AAs like classic VOMS) that do not support SOAP
> in the PGI
> > ecosystem?
> >
> >
> > Please feel free to comment but let the question of
> attributes+restrictions> outside - I propose to deal with it in
> separate threads because of their
> > complexity.
