java – 用于Thrift的Kerberos？

TServerSocket serverTransport = new TServerSocket(7911);  // new server on port 7911
HelloWorldService.Processor<Iface> processor = new HelloWorldService.Processer<Iface>(new ThriftServerImpl());  // This is my thrift implementation for my server
Map<String,String> saslProperties = new HashMap<String,String>();  // need a map for properties
saslProperties.put(Sasl.QOP,"true");
saslProperties.put(Sasl.QOP,"auth-conf");  // authorization and confidentiality

TSaslServerTransport.Factory saslTransportFactory = new TSaslServerTransport.Factory();     // Creating the server definition
saslTransportFactory.addServerDefinition(
            "GSSAPI",//  tell SASL to use GSSAPI,which supports Kerberos
            "myserviceprincipal",//  base kerberos principal name - myprincipal/my.server.com@MY.REALM 
            "my.server.com",//  kerberos principal server - myprincipal/my.server.com@MY.REALM
            saslProps,//  Properties set,above
            new SaslRpcServer.SaslGssCallbackHandler()));  //  I don't know what this really does... but I stole it from Hadoop and it works.. so there.

Tserver server = new TThreadPoolServer(newTThreadPoolSErver.Args(serverTransport).transportFactory(saslTrasnportFactory).processor(processor));

server.serve();   // Thrift server start

客户端代码示例

TTransport transport = new TSocket("my.server.com",7911);   // client to connect to server and port
saslProperties.put(Sasl.QOP,"auth-conf");  // authorization and confidentiality

TTransport saslTransport = new TSaslTransport(
            "GSSAPI",which supports Kerberos
            null,//  authorizationid - null
            "myserviceprincipal",//  base kerberos principal name - myprincipal/my.client.com@MY.REALM 
            "my.server.com",above
            null,//  callback handler - null
            transport);     //  underlying transport

TProtocol protocol = new TBinaryProtocol(saslTransport);    // set up our new Thrift protocol

HelloWorldService.Client client = new HelloWorldService.Client(protocol);   // Setup our thrift client
saslTransport.open();

String response = client.hello("Hi There");   // send message

System.out.println("response = " + response);

transport.close();

其他同意：
*我在客户端和服务器上设置了几个java属性.
– java.security.krb5.realm = MY.REALM //领域名称
– java.security.krb5.kdc = my.kdc.com // kdc服务器
– javax.security.auth.useSubjectCredsOnly = false //允许JAAS获取TGT.
– java.security.auth.login.config = /etc/myapp/conf/jaas.conf – 必需的jaas文件
– sun.security.krb5.debug = true //帮助诊断问题.
*上面指定的jaas.conf文件需要有两个条目(每个服务器可能只有一个……).我不记得从哪里收集了这些信息..但这是我的文件：

com.sun.security.jgss.initiate {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    keyTab="/etc/myapp/conf/myapp.keytab"
    useTicketCache=true
    principal="myuserprincipal"
    debug=true;
};

com.sun.security.jgss.accept {
    com.sun.security.auth.module.Krb5LoginModule required
    useKeyTab=true
    keyTab="/etc/myapp/conf/myapp.keytab"
    useTicketCache=false
    principal="myserviceprincipal/my.server.com"
    debug=true;
};

(回到考虑因素……)
*尽管Sasl.QOP为“auth-conf”..传输的第一条(？)消息未加密.也许这只是握手,或者其他什么.其余的消息似乎是加密的,但是第一个消息会向控制台输出一条丑陋的消息“没有加密是由同行执行的”.如果没有得到那条信息会很好,因为它会导致悲伤(保证或不保证).

无论如何,我希望这可以帮助某些人……或者可以激发一些对我有帮助的改进. :)很难相信我花了2-3天这样做,只有少量的代码出来了,但是当我开始时我既不知道Kerberos也不知道Thrift.

谢谢阅读.
