Client secret made optional for JWT Bearer Grant type
Resolved in Pega Version 8.6.3
After update, trying to connect a REST API using OpenAM as the provider for OAuth and using JWT Bearer as Grant type was resulting in an error indicating the request was not reaching the destination. This was traced to the client secret being designated a mandatory field when it should be optional in this case as the required key store was already configured with a JWT token profile. To resolve this, an update has been made which will make the client secret optional when the authentication scheme is JWT Bearer. In addition, the blank value caused a null pointer error when the client secret was not passed. This has been handled with a check.

Signature map updated for fetching keys
Resolved in Pega Version 8.6.3
MFA login worked with SAML 2.0 when the certificate was disabled but failed when the certificate was enabled in Auth Service. The error " "Signature algorithm is null" appeared. This has been resolved by updating the signature map to ignore case sensitivity while fetching keys.

DSS DisableAutoComplete setting honored
Resolved in Pega Version 8.7.2
Setting DisableAutoComplete DSS was not working as expected. This was traced to the system not being able to read the DSS value due to timing related to database startup, and has been resolved by directing the system to read the setting in PREnvironment.java instead of from the prconfig.

Ruleset creation process updated to maintain thread scope
Resolved in Pega Version 8.7.2
On creating a ruleset, the system generated the error "There has been an issue. Please consult your system administrator." If browser cookies and site settings were cleared and the browser was relaunched before logging in and creating a ruleset, the issue did not occur. Investigation showed that the Application page was at the Requestor scope for some of the threads due to handling in the ruleset creation process that removed the Application page and recreated it in the default scope of the thread with the latest state. To resolve this, the process for deleting the Application page and recreating it on the Requestor page has been removed.

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.
