Well the reason for this to make sure there is no spoofing, so I agree with the limitation that was put on this and opening this up is a security issue, so I'm aginst this

Subject	[higgins-dev] Re: Redirecting Bandit STS efforts to Higgins

So, as far as I understand the use case, I'm for adding the managedCardID.  The argument's I've heard against this say that if I want to have multiple managed cards backed by the same personal card, then those managed cards must represent the same identity in the backing store.  And if there's a need to use a different identity in the backing store, then a different personal card should be used.  While I agree that in practice this is likely the pattern that one should follow, but I don't like restricting the former possibility.

Mike,
 
I should have also replied about the following:
 
I also am waiting for the change to the IdAS described here: 
http://dev.eclipse.org/mhonarc/lists/higgins-dev/msg01601.html

This is the request that we allow managedCardID+PersonalCardPPID+modulus+exponent to be the auth material for a self-issued token.  I had some reservations, which I expressed in followup e-mails.  My 2nd-to-last email asked whether you meant managedCardID or managedCardPPID, and I pointed out problems with managedCardPPID. ... I guess I just wanted clarification that you really meant managedCardID, not managedCardPPID. ... I was under the impression that we still needed to have everyone accept the proposed idea.  I'm not sure where Jim and Tom are on the idea -- I will discuss it with them today to see what they think.  As I recall, they didn't chime in on the thread.

Thanks Mike. -- I did have a followup question on #2 (PPID claim handling).  This should be independent of SAML provider, so I'm not sure what you mean here.  All providers should do it this way, should they not?  Am I misunderstanding what you mean by SAML provider?  Could you clarify this?
 
I am also putting this particular e-mail out on the dev list - minus the other discussion about contributing to the STS.
 
Thanks,
 
Daniel

Allow 1 STS Core to be used by N STS Bindings - this is checked in today 
(you can now pass a configured STS instance into the binding configure 
method and get the configured STS instance from a binding).

PPID handling - this has been how the SAML provider works since the F2F.

Ask for specific claims when calling getDigitalSubject - this is checked 
in today (I still feel that this is an LDAPism and would like to discuss 
whether getDigitalSubject is expected to provide dynamic read-write access 
via an to the DigitalSubject or whether its expected to provide a static 
cached copy of the Digital Subject.

I also am waiting for the change to the IdAS described here:
