Subject: New Issue: Add single request for multiple tokens to WS-Trust

Artifact:  spec

Type: design

Title: Add single request for multiple tokens

Description:

There are occasions where efficiency is important. Reducing the  
number of messages in a message exchange pattern can greatly improve  
efficiency. One way to do this in the context of WS-Trust is to avoid  
repeated round-trips for multiple related token requests. An example  
is requesting an identity token as well as tokens that offer other  
claims in a single operation.

Related issues: none

Proposed Resolution:

Add a new Request element, RequestMultipleSecurityTokens, which  
allows the request of multiple tokens in a single request.  The  
existing RequestSecurityTokenResponseCollection allows multiple  
RequestSecurityTokenResponse elements to be contained in a single  
response and can be used to convey the reply to a  
RequestMultipleSecurityTokens request.

This proposal includes processing rules to keep the implementation  
simple and pragmatic, which is essential.

Suggested detailed proposal is attached in both Word and PDF format.

regards, Frederick
