Tableau Connector for Apache Impala

Build 24.0.9060

KerberosKDC

The Kerberos Key Distribution Center (KDC) service used to authenticate the user.

Data Type

string

Default Value

""

Remarks

The Kerberos properties are used when using SPNEGO or Windows Authentication. The connector will request session tickets and temporary session keys from the Kerberos KDC service. The Kerberos KDC service is conventionally colocated with the domain controller.

If Kerberos KDC is not specified, the connector will attempt to detect these properties automatically from the following locations:

  • KRB5 Config File (krb5.ini/krb5.conf): If the KRB5_CONFIG environment variable is set and the file exists, the connector will obtain the KDC from the specified file. Otherwise, it will attempt to read from the default MIT location based on the OS: C:\ProgramData\MIT\Kerberos5\krb5.ini (Windows) or /etc/krb5.conf (Linux).
  • Java System Properties: Using the system properties java.security.krb5.realm and java.security.krb5.kdc.
  • Domain Name and Host: If the Kerberos Realm and Kerberos KDC could not be inferred from another location, the connector will infer them from the configured domain name and host.
Note: Windows authentication is supported in JRE 1.6 and above only.
