<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">I would like to know your thoughts about the issue #52 of the CIBA spec:
<a href="https://bitbucket.org/openid/mobile/issues/52/ciba-pairwise-identifiers-structuring-text">
https://bitbucket.org/openid/mobile/issues/52/ciba-pairwise-identifiers-structuring-text</a> in order to resolve it:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt">As we know there is no way to use the sector_identifier if we cannot verify it and it seems that the only way to do it is to have a uri that belongs to the client. In order to resolve this issue
that is blocked for a long time, I propose to add some text to the spec. advising that is not possible to use Pairwise Identifiers when using polling in CIBA flow unless the client has registered the jwks_uri to sign request objects and use it as sector_identifier.
It must have another comment as well reminding that the jws_uri host should be the same as other used in other applications belonging to the same client where PPID’s are expected.<o:p></o:p></span></p>
