Which three data sources support Kerberos delegation with Tableau Server? (Choose three.)
A.
Teradata
B.
PostgreSQL
C.
SQL Server
D.
SAP HANA
The Answer Is:
A, C, D
This question includes an explanation.
Explanation:
Kerberos delegationallows Tableau Server to pass a user’s Kerberos credentials to a data source for seamless authentication (SSO)—let’s explore which sources support it:
Kerberos Overview:
Used with Active Directory (AD) for SSO in Windows environments.
Tableau Server delegates the user’s ticket to the data source, avoiding embedded credentials.
Supported Data Sources: Per Tableau’s documentation:
Option A (Teradata): Correct.
Details: Supports Kerberos delegation—common in enterprise data warehouses.
Config: Enable in TSM (tsm authentication kerberos configure) and set SPN for Teradata.
Option C (SQL Server): Correct.
Details: Fully supports Kerberos—widely used with AD-integrated SQL Server instances.
Config: Requires AD setup and "Trustworthy" delegation in SQL Server.
Option D (SAP HANA): Correct.
Details: Supports Kerberos SSO via delegation—popular in SAP ecosystems.
Config: Needs HANA Kerberos setup (e.g., keytab) and Tableau Server integration.
Option B (PostgreSQL): Incorrect.
Why: Supports Kerberos authentication natively, but Tableau Server doesn’t enable delegation to PostgreSQL—users must embed credentials or use other methods (e.g., OAuth).
Why This Matters: Kerberos delegation enhances security by avoiding stored passwords—knowing supported sources ensures SSO feasibility.
