问题


Qn: If i've diff kerberos Realms, and the broker sits on Linux and producer sits on windows, how do enable the connectivity using Kerberos? I have valid keytab. and here is the krb5

Please see marked answer to this question in this link.

Connect to Kafka on Unix from Windows with Kerberos

below question is continuation for 3rd scenario explained by @Samson. answering some of Samson's suggestions, 1 default realm is added in krb5. 2.there is one way trust. the broker domain trusts my domain.

 [libdefaults]
 renew_lifetime = 7d
 forwardable = false
 default_realm = SomeUrl.COM
 ticket_lifetime = 24h
 dns_lookup_realm = false
 dns_lookup_kdc = false
 udp_preference_limit = 1


 [domain_realm]

 .machine.test.group = SomeUrl.COM  
  machine.test.group = SomeUrl.COM

  [realms]
  SomeUrl.COM = {
  admin_server = SomeUrl.COM
  kdc = SomeUrl.COM
  }

SomeUrl.com is where the broker is placed.

here is the log from producer for this scenario.

producer connection to broker log: (I've edited the actual broker name and IP address)
