Hello Kafka,
I am Mohammed Amine GARMES from AMADEUS SAS.
First of all I want to thank you for your solution is very helpful.
Indeed, this is my first message to Kafka team, so I have an issue with Kafka
security :
I have 2 kafka servers configured to start with kafka security, I try to start
the akfka servers with the JASS below ==>
server 1
KafkaServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
// ZooKeeper client authentication
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
server 2 :
KafkaServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
// ZooKeeper client authentication
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
the problem:
when I start the kafka server 1 all is fine, but when I try to start the second
server I have an issue because it haven't the access to the zookeeper node
(/brokers) for kafka. the all zookeeper path /brokers is blocked by the first
server, so the second server haven't the right access to write in this path .
The ACL of /brokers is the fqdn of the first server, normally should be open
for all and close ACL of the path /broker/ids/1, in this case the second server
can write in /brokers and close the /brokers/ids/2 for him.
I founded a solution but I am not sure that the right solution, I create a new
kakfa-kerberos user, so for all server I use the same user :
Server1
KafkaServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
// ZooKeeper client authentication
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafkaZk.keytab"
principal="kafka/[email protected]";
};

Server2
KafkaServer {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafka.keytab"
principal="kafka/[email protected]";
};
// ZooKeeper client authentication
Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
storeKey=true
keyTab="/opt/kafka/config/kafkaZk.keytab"
principal="kafka/[email protected]";
};
Can help me or clarify to me how I can use Kafka security correctly ?!!
