zookeeper sasl authentication issue

Question

I am trying to have setup SASL authentication for my zookeeper for Kafka. I followed all the steps mentioned in below link

https://cwiki.apache.org/confluence/display/ZOOKEEPER/Client-Server+mutual+authentication

Below is my server_jaas.conf file kept in /home directory

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

Below is my java.env file configuration

SERVER_JVMFLAGS="-Djava.security.auth.login.config=/home/server_jaas.conf"

Below is the error I get

2017-08-01 16:49:40,774 [myid:] - ERROR [main:ServerCnxnFactory@199] - No JAAS configuration section named 'Server' was foundin '/home/server_jaas.conf'.

Answer 1

Try adding ; to the end of your server definition

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

Answer 2

The content of config file could be like this:

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

and make sure the location of /home/server_jaas.conf is correct.

I got the same exception since I gave a wrong location of this config file.
