Subject: [wsrp] RE: [wsia] [wsia-wsrp] 8/27/2002: Upcoming WS-Security OASIS TCM eeting


Roles and user identity are really distinct concepts.  Roles provide a way
of grouping principals(users/groups) with similar attributes into a class
that can be used for defining access control policies.  A given user's
identity does not need to be known to a particular application for
role-based access control to be used by that application.  

User identity mapping is useful for distributed systems that don't share a
common identifier for a user.  A common WSRP use case is one where a
Producer provisions user accounts in some back end application for each
end-user.  These user accounts may not be based on the identity the user
authenticates with at the Consumer.  In this case, a mapping is needed
between the Consumer's authenticated identity and the back end application's
identity for the user. 

WS-Security had no notion of identity mapping, at least in the original spec
draft.  I haven't looked at the recent addendum.

Hi Monica.

Great that you are attending the meeting, that will give us the oppotunity
to fix some outstanding questions. My current questions/concerns are:

- will our role concept become obsolete in the near future? Will there be
WS standards that handle role transfer/mapping directly inside the SOAP
stack?
- is what we define a "role" really a role from a security standpoint or
rather a delegated user identity? Maybe the correct approach would be to
let WS security send a couple of user identities rather than inventing our
own role concept. Is this possible in WS-Security? Would it be the correct
approach
- does WS-Security define user identity mapping? If not how is the transfer
of user identity supposed to work? Will there be an upcoming standard? Is
the user identiy programmatically accessible? When will that be
incorporated in standard SOAP stacks (AXIS, .NET)?

- the basic question is: should be define security directly in our protocol
at all or will WS-security and forthcoming standards handle this problem.

Best regards
Carsten Leue

I hope to be attending the upcoming WS-Security opening TC next week
from 4-5 September 2002 in Redwood City. As this related standards
development complements or affects our work, I am asking if you have
general questions or inputs?  I could be more focused in providing any
feedback for the benefit of the WSRP-WSIA efforts.

Thank you.
