java - 使用HTTP客户端的Kerberos连接

我正在使用Kerberos身份验证编写HTTP连接。我有“未经授权的HTTP/1.1 401”。您能推荐我应该检查的内容吗？我认为有一些窍门，但我看不到。

我可以将标题“WWW-Authenticate”设置为“Negotiate”吗？

非常感谢您提供的任何帮助和想法。

public class ClientKerberosAuthentication {

    public static void main(String[] args) throws Exception {

        System.setProperty("java.security.auth.login.config", "login.conf");
        System.setProperty("java.security.krb5.conf", "krb5.conf");
        System.setProperty("sun.security.krb5.debug", "true");
        System.setProperty("javax.security.auth.useSubjectCredsOnly","false");

        DefaultHttpClient httpclient = new DefaultHttpClient();
        try {
           NegotiateSchemeFactory nsf = new NegotiateSchemeFactory();
           httpclient.getAuthSchemes().register(AuthPolicy.SPNEGO, nsf);

           List<String> authpref = new ArrayList<String>();
           authpref.add(AuthPolicy.BASIC);
           authpref.add(AuthPolicy.SPNEGO);
           httpclient.getParams().setParameter(AuthPNames.PROXY_AUTH_PREF, authpref);


           httpclient.getCredentialsProvider().setCredentials(
                  new AuthScope(null, -1, AuthScope.ANY_REALM, AuthPolicy.SPNEGO),
                  new UsernamePasswordCredentials("myuser", "mypass"));

           System.out.println("----------------------------------------");
           HttpUriRequest request = new HttpGet("http://localhost:8084/web-app/webdav/213/_test.docx");
           HttpResponse response = httpclient.execute(request);
           HttpEntity entity = response.getEntity();

           System.out.println("----------------------------------------");
           System.out.println(response.getStatusLine());
           System.out.println("----------------------------------------");
           if (entity != null) {
               System.out.println(EntityUtils.toString(entity));
           }
           System.out.println("----------------------------------------");

           // This ensures the connection gets released back to the manager
           EntityUtils.consume(entity);

        } finally {
           httpclient.getConnectionManager().shutdown();
        }
    }
}

最佳答案

SPNEGO将不起作用，因为您使用localhost作为URL主机名。

为服务器配置了一组SPN(或至少一个SPN)，这些SPN以在ActiveDirectory服务帐户中注册的HTTP/开头。您可以通过setspn -l yourServiceAccount从AD中查询它们。

您的URL必须使用ActiveDirectory中称为SPN的有效服务器主机名，以便Apache Http Client可以为此服务协商TGS并将其发送到您的服务器。
