The AD domain controller automatically creates a Kerberos account for this user with an accompanying keytab. Note the following:. You can generate and export the keytab file for the Kerberos account by using the Ktpass tool.

Note that the version of the Ktpass tool that you use must match the Windows version of the domain controller. You enter different commands for generating and exporting the keytab file, depending on whether you are generating the keytab file from a server running Microsoft Windows , Windows Server , Windows Server , or Windows Server R2.

COM -mapuser ns1 corpxyz. To export the keytab file using a Microsoft Windows Resource Kit:. This must be des-cbc-md5. Include this if you did not enable DES encryption for the account. A Windows Server or Windows Server R2 domain controller allows you to generate a keytab file with multiple keys for one principal. To generate the keytab file using the Ktpass tool:. COM-mapuserns1 corpxyz. After you execute the command to generate the keytab file, the AD domain controller displays a series of messages similar to the following to confirm that it successfully generated the keytab file: Targeting domain controller: qacert.

The keytab file contains highly sensitive data for the NIOS appliance account. Ensure that you store and transport its contents securely. To import the keytab file:. If a principal name and version number are listed, there is a keytab file loaded on the appliance. Compare this information with that for the NIOS appliance account on the Kerberos server to make sure that they match.

If there is no keytab file on the NIOS appliance or if the loaded keytab file does not match that on the Kerberos server, you must load the correct keytab file.
