conduktor connection error

[#1]

Hello Team,

can you please advise why connection to Kafka fails? Is the issue with keytab? Keytab is working fine on Linux machine.

sasl.jaas.config= com.sun.security.auth.module.Krb5LoginModule required useKeyTab=true keyTab="D:\services.kerberos.keytab" principal="services/[email protected]";

@roshanbi 

Have you tried specifying the krav path as shown below instead?

keyTab="D:/services.kerberos.keytab"

Please use a forward slash instead of a backslash.

Cheers

Andre
