From source file:org.elasticsearch.xpack.security.authc.kerberos.SpnegoHttpClientConfigCallbackHandler.java

private void setupSpnegoAuthSchemeSupport(HttpAsyncClientBuilder httpClientBuilder) {
    final Lookup<AuthSchemeProvider> authSchemeRegistry = RegistryBuilder.<AuthSchemeProvider>create()
            .register(AuthSchemes.SPNEGO, new SPNegoSchemeFactory()).build();

    final GSSManager gssManager = GSSManager.getInstance();
    try {//  w ww .j a va 2 s . c  o m
        final GSSName gssUserPrincipalName = gssManager.createName(userPrincipalName, GSSName.NT_USER_NAME);
        login();
        final AccessControlContext acc = AccessController.getContext();

                        GSSCredential.INITIATE_ONLY),
