Support form_post response mode in OAuth Authorization Code Flow

We use API Connect as an IDP. Some of our service providers are looking to enable an SSO integration and they have requested support of form_post response_mode in the OAuth Authorization Code Flow. We found that this is not currently supported.

    The impact to us is that we have an SSO implementation with a vendor for our finance chargeback system. Their integration currently works only with support form_post response mode. This puts our integration at risk and impacts the overall digital transformation strategy at MSK.

    The OIDC extends, and in some cases, overrides, the OAuth 2.0 standard, and this is one of those cases.

    Please reference the OIDC core 1.0 standard:, section pasted below. Authentication Request

    An Authentication Request is an OAuth 2.0 Authorization Request that requests that the End-User be authenticated by the Authorization Server. Authorization Servers MUST support the use of the HTTP GET and POST methods defined in RFC 2616 [RFC2616] at the Authorization Endpoint. Clients MAY use the HTTP GET or POST methods to send the Authorization Request to the Authorization Server. If using the HTTP GET method, the request parameters are serialized using URI Query String Serialization, per Section 13.1. If using the HTTP POST method, the request parameters are serialized using Form Serialization, per Section 13.2.
