Authentication 卡夫卡·萨斯勒：非统派和普通派同时存在

我想做的是-

For Clients to Broker communication - use OAUTHBEARER authentication
For Broker to Broker communication - use PLAIN authentication

我有以下JAAS配置：

{
  KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="inter"
    password="inter-secret"
    user_inter="inter-secret"
    user_admin="YvNzcbmqhA0DfxjP";

    org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required;
  };

  Client {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="zookeeper"
    password="zookeeper-secret";
  };
}

internal.KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="admin-secret"
    user_admin="admin-secret"
    user_test="test";
};

external.KafkaServer {
    org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required
};

Client {
   org.apache.zookeeper.server.auth.DigestLoginModule required
   username="username"
   password="pw";
};

我在server.properties中有以下配置：

sasl.enabled.mechanisms=PLAIN,OAUTHBEARER
sasl.mechanism.inter.broker.protocol=PLAIN
sasl.server.callback.handler.class=br.com.jairsjunior.security.oauthbearer.OauthAuthenticateValidatorCallbackHandler

但如果启动卡夫卡服务，我会看到如下错误：

used by: java.lang.IllegalArgumentException: Must supply exactly 1 non-null JAAS mechanism configuration (size was 2)
at org.apache.kafka.common.security.oauthbearer.internals.unsecured.OAuthBearerUnsecuredValidatorCallbackHandler.configure(OAuthBearerUnsecuredValidatorCallbackHandler.java:114)
at org.apache.kafka.common.network.SaslChannelBuilder.configure(SaslChannelBuilder.java:122)
... 17 more

CLient to Broker ----> OAUTHBEARER
Broker to Broker ----> PLAIN

这表明kafka不允许指定多个JAAS机构配置

因此，如何指定多个JAAS配置，并设置如下所示的身份验证机制：

used by: java.lang.IllegalArgumentException: Must supply exactly 1 non-null JAAS mechanism configuration (size was 2)
at org.apache.kafka.common.security.oauthbearer.internals.unsecured.OAuthBearerUnsecuredValidatorCallbackHandler.configure(OAuthBearerUnsecuredValidatorCallbackHandler.java:114)
at org.apache.kafka.common.network.SaslChannelBuilder.configure(SaslChannelBuilder.java:122)
... 17 more

CLient to Broker ----> OAUTHBEARER
Broker to Broker ----> PLAIN

谢谢

我目前也在研究同时使用plain和oauthBear的问题，我还没有解决这个问题，但我用以下方式解决了您的具体问题。 这是我的Jaas配置：

{
  KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="inter"
    password="inter-secret"
    user_inter="inter-secret"
    user_admin="YvNzcbmqhA0DfxjP";

    org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required;
  };

  Client {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="zookeeper"
    password="zookeeper-secret";
  };
}

internal.KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="admin"
    password="admin-secret"
    user_admin="admin-secret"
    user_test="test";
};

external.KafkaServer {
    org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule required
};

Client {
   org.apache.zookeeper.server.auth.DigestLoginModule required
   username="username"
   password="pw";
};

然后，我在server.properties中按以下方式设置设置：

  inter.broker.listener.name: INTERNAL 
  sasl.mechanism.inter.broker.protocol: PLAIN
  listener.security.protocol.map: INTERNAL:SASL_PLAINTEXT,EXTERNAL:SASL_SSL
  listeners: "INTERNAL://0.0.0.0:9092,EXTERNAL://0.0.0.0:19092"
  sasl.enabled.mechanisms: PLAIN,OAUTHBEARER

  listener.name.external.oauthbearer.sasl.server.callback.handler.class: my.module.kafka.security.oauthbearer.OauthAuthenticateValidatorCallbackHandler
  listener.name.external.oauthbearer.sasl.login.callback.handler.class: my.module.kafka.security.oauthbearer.OauthAuthenticateLoginCallbackHandler

如果你这样做，你就不会犯错误。遗憾的是，当代理想要设置外部连接时，我遇到了另一个错误：

javax.security.auth.callback.UnsupportedCallbackException: Unrecognized SASL Login callback
    at org.apache.kafka.common.security.authenticator.AbstractLogin$DefaultLoginCallbackHandler.handle(AbstractLogin.java:105)
    at org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule.identifyToken(OAuthBearerLoginModule.java:316)
    at org.apache.kafka.common.security.oauthbearer.OAuthBearerLoginModule.login(OAuthBearerLoginModule.java:301)
    ... 32 more

卡夫卡经纪人似乎忽视了OAuthBearner callbackhandler。这有点奇怪，因为当我将external配置为唯一的侦听器时，它可以完美地工作

我希望它能帮助你解决你的问题
