Key ID made optional for JWT
Resolved in Pega Version 8.6.5
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.

Updated OAuth2 registration handling for modified application definition
Resolved in Pega Version 8.6.5
After update, attempting to resave an application definition after any modification resulted in the error "Application OAuth2 client registration is failed. Error Message: PegaApp_XXBase:Client already exists". This was due to pxCreateRecord being called to create the authentication profile: as it was already present, it failed to create a new one. This has been resolved by changing pxCreateRecord to Obj-Save in this process. This change will only be applied on newly created applications using the Data-Application-OAuth2ClientRegistration instance. The solution for already exported applications is to delete the corresponding OAuth2 client (PegaApp_<application id>) and resave the application to create a new client along with the needed metadata.

Updated support for Client Assertion in Open ID Connect to generate unique JTI
Resolved in Pega Version 8.6.5
Following an update with an enhancement which added UI and code changes to support Client Assertion in Open ID Connect, the token expiry and issue dates were not getting set properly and the JTI was not getting generated. This has been resolved by adding code to generate a unique client_assertion on OIDC login with private_key_jwt so the JTI in client assertion will be be unique for every login.
