                    Rejecting of the client certificate by the security domain will not prevent the connection.
                    Allows a fall through to use other authentication mechanisms (like form login) when the client certificate is rejected by security domain.
                    Has an effect only when the security domain is set.
                    This does not bypass the underlying trust manager check - see need-client-auth to allow connection without client certificate.

                            It is possible that a KeyStore definition can be created to a
                            non-existent file and the file be automatically created when the store is saved, however
                            no error will be reported where the file does not exist to begin with.

                            If the intent is that the store will always exist in advance set
                            this to 'true' so that an error will be reported if the file is missing.
