[Bug] [iPad - iOS15.1] Cordova advanced http - sendRequest is not showing up auth-Prompt screen for New Kerberos SSO - credential based auth challenge on iOS 15.1

[ManiyamGT]

Description We have a Hybrid iOS Application build on Cordova Plugin and 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 worked with Old 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 attached prompt screen when using Old Kerb -SSO but it’s not showing up after New Kerberos SSO. and we have not modified any single line of change in code.

• affected platform(s) and version(s): [iOS 15.1]

                        (result) => {
                                    // Success handleing code.
                            },
                        (error) => {
                                    // Error handleling code. 
                            }
