Teradata Vantage clients use Service Principal Names (SPNs) to specify the Vantage node or Unity server to which they want to connect.
SPNs use the following format:
- Requests the service, that is, a Teradata Vantage or Unity server.
- Example: TERADATA
- Specifies the Fully Qualified Domain Name (FQDN) for a database node or Unity server, composed of:
- A name created in step 4 of Creating a Computer Component for Database Nodes and Unity Server, for example, tdatsysa1-1.
- The domain path to the node or Unity server, taken from step 3 of Adding a Database Node or Unity Server to the Windows DNS, in the form: subdomain.domain.com The domain information you enter for instance is case sensitive. Even if the domain name has upper case characters, you must be specify it in the ktpass command using lowercase.
- The domain information can include one or more additional sub-domain specifications if required to uniquely locate the node or Unity server.
- The name of the Kerberos realm containing the node or Unity server.The realm information must match the Windows domain exactly including case.
The realm specified for this term can include one or more additional sub-realm specifications if required to uniquely identify the realm.
- Example: CORP.TERADATA.COM
Determine the SPNs for all nodes and Unity servers defined in step 4 of Creating a Computer Component for Database Nodes and Unity Server, for all Teradata Vantage systems and Unity servers served by the KDC. Retain the SPN information for use in Running ktpass to Create the Kerberos Keys.
