Re: [provision] A Proposal for using DSML for Provisioning

[jbohren@opennetwork.com (Jeff Bohren)]

That is pretty much the gist of it, as I see it. There is an implied third party, which is the party (most likely a system) that makes the request at the
protocol layer. Suppose that the RA is a provisioning system (system A) in one domain and the PSP is a provisioning system (system B) in another. There is
a supervisor user named jdoe that has rights to request a PSTD for jsmith. Now the trust relationships would be:

Systems A and B have a trust relationship.
System A has the rights to impersonate user jdoe.
jdoe has the rights to request a PSTD for user jsmith

So then the flow might be:

1) jdoe requests a PSTD for jsmith in System A.
2) System A sends a DSML addRequest to System B, using the authRequest tag to refer to jdoe.
3) System B processes the request and sends a response to System A.
4) System A sends a response to jdoe.

In this case System B has knowledge of all three parties involved in the request.

Although these are interesting questions, does anyone have any comments about the overall notion of using DSML for provisioning? Is this something that
makes sense?
