Subject: Re: Configuring OIDC to use client_credentials - InvalidMessageContext
Hi Gary,
I was finally able to reproduce the behaviour with the following remarks:
- scope 'openid' is registered in the metadata (like you do) and also
requested by the client. This is the main reason for the confusing logs:
the current code is using that scope to signal the use of OpenID Connect
sequence, which is never the case with the client credentials grant. If
you remove the use of that scope, you'll probably see error message with
description "Improper or disallowed resource indicator".
- The error description above is related to the lack of using resource
indicator in the request, or the client does not have any registered
audiences. See
https://aus01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fshibboleth.atlassian.net%2Fwiki%2Fspaces%2FSC%2Fpages%2F1912406916%2FOAuthRPMetadataProfile&data=05%7C02%7Cglipscomb%40csu.edu.au%7C960ba6ad52b74834f9cc08dcc7f6300b%7Cf0f76207a6104fc0b4a35d797fe5283c%7C0%7C0%7C638605107406790513%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=UJh5E4ZJAgrY4TIGgw2PA8Gle7kAeinlav8FT4pjHwI%3D&reserved=0<https://shibboleth.atlassian.net/wiki/spaces/SC/pages/1912406916/OAuthRPMetadataProfile>
. The logic is that unless the client requests any specific resource,
the first registered audience is used as the access token
target/audience. In any case, the registered resources need to have
OAUTH2.TokenAudience profile enabled. You should have that covered as
you've enabled it via DefaultRelyingParty.
Regarding the scopes, until OP 4.1.0 you need to be using some scope
value in the request. See https://aus01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fshibboleth.atlassian.net%2Fbrowse%2FJOIDC-176&data=05%7C02%7Cglipscomb%40csu.edu.au%7C960ba6ad52b74834f9cc08dcc7f6300b%7Cf0f76207a6104fc0b4a35d797fe5283c%7C0%7C0%7C638605107406801278%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=9SsFLo2UGA31lODR72xruDw2QzlwNli3P%2FXkVVZWtpk%3D&reserved=0<https://shibboleth.atlassian.net/browse/JOIDC-176>
