Both AuthenticationMethods resulted failure

[Leon16]

I tried the Example code and set different preferredAuthMethods .ciam and .keycloak in the following method:

let config = MBMobileSDKConfiguration(applicationIdentifier: "example",
                                          authenticationConfigs: [
                                            ROPCAuthenticationConfig(clientId: clientId, type: .keycloak),
                                            ROPCAuthenticationConfig(clientId: clientId, type: .ciam)
                                          ],
                                          endpoint: MBMobileSDKEndpoint(region: .ece,
                                                                        stage: .mock),
                                          preferredAuthMethod: .ciam) <---- set either .ciam or .keycloak

Here is the result value from the following call:

    loginProvider.login(username: username, credential: self.credential(for: loginProvider.type, pin: pin, nonce: nonce)) { [weak self] result in

        switch result {
        case .success:
            LOG.V("Succcessfully logged in user; Fetching user data...")
            self?.fetchUser(completion: completion)

        case .failure(let error):
            LOG.E("Login request did fail with error: \(error)")
            completion(.failure(error))
        }
    }

case 1: when loginProvider.type = .keycloak the result is:

(lldb) p result (Result<Void, MBMobileSDK.LoginServiceError>) $R7 = failure { failure = loginDidFail { loginDidFail = some { type = unknown description = nil } } }

case 2: When the loginProvider.type = .ciam the result is:

(lldb) p result (Result<Void, MBMobileSDK.LoginServiceError>) $R0 = failure { failure = loginDidFail { loginDidFail = some { type = http { http = unauthorized { unauthorized = { data = 86 bytes } } } description = "invalid_client -> Invalid client or client credentials." } } } (lldb)

In case 2 I tried to use the valid client Id allocated to me in my developer account console but still got the same error.

regression - Whether I set the sdk endpoint as the following resulted the same error:

MBMobileSDKEndpoint(region: .ece, stage: .mock) or MBMobileSDKEndpoint(region: .ece, stage: .prod)

It looks like the authentication server has bug which simply prevent the authentication from MobileSDK. The same authentication mechanism used in log into developer account works fine.
