- You have HTTP Authorization Manager added, "KERBEROS" mechanism selected, Realm and other fields populated
- You use HTTPClient4 implementation
- You have proper configuration in krb5.conf and jaas.conf files
- Your system.properties file contains following entries
- java.security.krb5.conf=krb5.conf
- java.security.auth.login.config=jaas.conf
JMeter restart is required after step 4
