Which three data sources support Kerberos delegation with Tableau Server? (Choose three.)
AnswerA, C, D
ExplanationKerberos delegation allows 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.
Requires:
Data source support for Kerberos.
Proper configuration (e.g., SPN, constrained delegation).
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.
