Review the Service Principal Name and Keytab File Name Format Text File

Review the Service Principal Name and Keytab File Name Format Text File

After you generate the SPNKeytabFormat.txt file, you can review the file.
You use the information in the file to generate the keytab files, and to associate each SPN with the corresponding principal user account in Active Directory.
The SPNKeytabFormat.txt file contains the following information:
Entity Name
Identifies the node or service associated with the process.
Service Principal Name
Format for the SPN. The SPN is case sensitive.
If you enter a string containing multiple Kerberos domain names, or add an asterisk before a realm suffix to include all realms that include the suffix, the SPN format does not include the realm name.
The following table describes the SPN formats:
Keytab type SPN Format
NODE_SPN isp/<node name>/<domain name>@<REALM NAME>
NODE_AC_SPN _AdminConsole/<node name>/<domain name>@<REALM NAME>
NODE_HTTP_SPN HTTP/<node host name>@<REALM NAME>
The Kerberos SPN Format Generator validates the node host name. If the node host name is not valid, the utility does not generate an SPN. Instead, it displays the following message: Unable to resolve host name.
SERVICE_PROCESS_SPN <application service name>/<node name>/<domain name>@<REALM NAME>
Keytab File Name
Format for the name of the keytab file to be created for the associated SPN. The keytab file name is case sensitive.
The following table describes the keytab file name formats:
Keytab Type Keytab File Name
NODE_SPN <node name>.keytab
NODE_AC_SPN _AdminConsole.keytab
NODE_HTTP_SPN webapp_http.keytab
SERVICE_PROCESS_SPN <application service name>.keytab
