We have a Hybrid iOS Application build on Cordova Plugin, and it worked with Old Kerberos SSO -credential based authentication. Recently, we have updated the New Kerberos based SSO by following the presentation ( https://developer.apple.com/videos/play/tech-talks/301/ ) . After which the hybrid app is not prompting for the HTTP response challenge, but it should support for the New Kerberos SSO – credential-based authentication. We could see the response header has the below attribute for SSO handshake challenge.   Www-Authenticate: Negotiate, Basic realm="IBM Security Access Manager for Web" But the auth prompt screen is not appearing, and connection is throwing with 401-unauthenticated response. Note : We can see this below prompt for Old Kerb -SSO but it’s not showing up after New Kerberos SSO. System Specification: XCode – 13 Cordova 6.2.0 iPad -15.0 Please let us know if any solution would solve this. Thanks
