Hmm... perhaps the clue is in the draft title, token-exchange, so may be it is a case of the given access token ("on_behalf_of" or "act_as" claim) being used to request a new security token. One can only guess though, does not seem like the authors are keen to answer the newbie questions...

Cheers, Sergey

Hi,
Can you please explain what is the difference between On-Behalf-Of
semantics described in the draft-ietf-oauth-token-exchange-01 and the
implicit On-Behalf-Of semantics a client OAuth2 token possesses ?

For example, draft-ietf-oauth-token-exchange-01 mentions:

"Whereas, with on-behalf-of semantics, principal A still has its own
identity separate from B and it is explicitly understood that while B
may have delegated its rights to A, any actions taken are being taken by
A and not B. In a sense, A is an agent for B."

This is a typical case with the authorization code flow where a client
application acts on-behalf-of the user who authorized this application ?

Sorry if I'm missing something

Cheers, Sergey

Hi All,

   I am looking to solve a use-case similar to WS-Security On-Behalf-Of
<http://docs.oasis-open.org/ws-sx/ws-trust/v1.4/errata01/os/ws-trust-1.4-errata01-os-complete.html#_Toc325658980>

with OAuth JWT Token.

   Is there a standard claim which we can define within the OAuth JWT
which denote the On-behalf-of User.

For e.g., a Customer Representative trying to create token on behalf of
a customer and trying to execute services specific for that specific
customer.

Regards,

Vivek Biswas,
