<div dir="ltr"><div><div><div><div>That raises some different questions than I had in mind.<br><br></div>I'd say if the OP needs something on the endpoint like that, whatever it might be, then yes they include it all and let the client discover and use it. That probably suggests that language is needed for the endpoint saying that it may include a query component which must be retained (similar to what RFC 6749 has in a few places in the endpoints section). <br>
<br></div>The questions I was getting at are if an extensibility point is needed for the schema of the UserInfo Endpoint at all? If so, both client and OP need to understand it, which suggests maybe supported schema types need to be advertized in discovery. And maybe included in registration. And if you do that, the need for a parameter on the UIEP maybe goes away The more I think about it, the more it seems this extensibility point isn't fully baked. <br>
<br></div>But I digress. What I was originally asking for was to not make schema required and let openid be the default value when it's not specified. It's award to have only one possible value for a parameter but require that everyone send exactly that value all the time.<br>
<br></div><div>I'm also still confused about why there's this reserved id parameter there. What's the point? Wouldn't saying something general about ignoring other parameters be more appropriate? If anything needs to be said at all.<br>

<p>Having read §2.3.1 (UserInfo Request), first I think something like these words are missing before the list "The following request parameters are used with the UserInfo endpoint:". I can add those.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>However, looking at this again, I believe there's an ambiguity whether the client adds the "schema=openid" parameter or not. Making this concrete, I believe that the URL of Google's UserInfo Endpoint is:<u></u><u></u></p>
<p> <a href="https://www.googleapis.com/oauth2/v3/userinfo?schema=openid" target="_blank">
<span style="color:windowtext;text-decoration:none">https://www.googleapis.com/oauth2/v3/userinfo?schema=openid</span></a><u></u><u></u></p>
<p>They've already added the parameter to their endpoint address.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>Should they actually be advertising this UserInfo endpoint address instead:<u></u><u></u></p>
<p> <a href="https://www.googleapis.com/oauth2/v3/userinfo" target="_blank">
<span style="color:windowtext;text-decoration:none">https://www.googleapis.com/oauth2/v3/userinfo</span></a><u></u><u></u></p>
<p>with the expectation that the Client will add the "schema=openid" parameter?<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>I think we may need to be clearer on this.<u></u><u></u></p>

<p>At around the time, we switched from SCIM schema to the flat schema due to developer requests at the time. However, we wanted to provide the ability to specify other scheme name such as scim to get the data in that format if the server
supports.<u></u><u></u></p>
