UI and code changes to support Client Assertion in Open ID Connect
Resolved in Pega Version 8.7.2
In order to support private_key_jwt, an enhancement has been added which will pass the “Client ID” and “Client assertion” (in the form of a signed JWT) as part of the authorization code grant flow for an IDP-initiated SSO. The Authorization Server will then authenticate Pega (the client) to verify the signature and payload of assertion by retrieving the public key via Pega’s JWKS endpoint.

at+jwt header type support added
Resolved in Pega Version 8.7.2
After upgrading from Pega 7 to Pega 8, using JWT validation in the REST service package with type "at+jwt" resulted in the JSON web token being rejected during signature verification with the error "header "typ" (type) "at+jwt" not allowed". Pega uses the third-party Nimbus jar to generate and verify JWT tokens, and this issue was traced to a difference in the versions of that jar: Pega 7.3 uses the nimbus-jose-jwt 5.1 version jar, while Pega 8.6+ uses the 8.20 jar version. Nimbus rejects at+jwt header types by default from the 8.0 jar version. To resolve this and improve backwards compatibility, at+jwt header type support has been added.

Key ID made optional for JWT
Resolved in Pega Version 8.7.2
After update, Connect-REST services were failing with a Admin_Security_Token.Action error. This was traced to kID (key ID) being mandated following previous work done to address an issue. To resolve this and better support backwards compatibility, the kID has been made optional in the JWT header.
