Hi all

Following the virtual interim meeting discussion last week about "OAuth Pro=
of of Possession Tokens with HTTP Message Signature" my main concern is abo=
ut the unclear boundary between draft-ietf-oauth-dpop<https://datatracker.i=
etf.org/doc/draft-ietf-oauth-dpop/> and the OAuth Proof of Possession Token=
s with HTTP Message Signature solution and the resulting confusion by devel=
opers.

Several active working group participants have in the past expressed concer=
ns about the confusion our specification create in the developer community.=
 Having two (or more) solutions that offer the same or similar functionalit=
y will for sure lead to confusion.

If the group could come up with a description of when to use what solution =
that would be valuable. At the conference call there was a disagreement bet=
ween Brian and Justin about where that boundary is.

Ciao
Hannes

<p class=3D"MsoNormal">Hi all<o:p></o:p></p>
<p class=3D"MsoNormal"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoNormal">Following the virtual interim meeting discussion las=
t week about &#8220;OAuth Proof of Possession Tokens with HTTP Message Sign=
ature&#8221; my main concern is about the unclear boundary between
<a href=3D"https://datatracker.ietf.org/doc/draft-ietf-oauth-dpop/">draft-i=
etf-oauth-dpop</a> and the OAuth Proof of Possession Tokens with HTTP Messa=
ge Signature solution and the resulting confusion by developers.
<o:p></o:p></p>
<p class=3D"MsoNormal"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoNormal">Several active working group participants have in th=
e past expressed concerns about the confusion our specification create in t=
he developer community. Having two (or more) solutions that offer the same =
or similar functionality will for
 sure lead to confusion. <o:p></o:p></p>
<p class=3D"MsoNormal"><o:p>&nbsp;</o:p></p>
<p class=3D"MsoNormal">If the group could come up with a description of whe=
n to use what solution that would be valuable. At the conference call there=
 was a disagreement between Brian and Justin about where that boundary is.
<o:p></o:p></p>

<p class=3D"MsoNormal">Ciao<o:p></o:p></p>
