Title: SAML and EBMS 3.0 [SEC=UNCLASSIFIED]

Hi All,

            Received the following from one of my colleagues in the Australian Government. I am assuming that dual signing is neither desirable nor intended.
 Is this something we can discuss and clarify?

 

Regards, Ian.

Hi Malcolm, Ian,

There are currently some discussions going on here about the EBMS standard. I was pulled in to give my opinion about the following extract from the standard and how it affects us using SAML
 with EBMS.

Without looking deeply into the context my answer was that SAML could not be used as the sole mechanism for message integrity. If SAML signing were used (and we didn't want to break the standard)
 then we would have a dual signed EBMS message.

Do you have a different view?

Thanks.
