Generating Keytab Files for the SPN User

Generating Keytab Files for the SPN User

Use the Microsoft Windows Server ktpass utility to generate a keytab file for the SPN user.
You must generate the keytab files on a member server or on a domain controller within the Active Directory domain. You cannot generate keytab files on a workstation operating system such as Microsoft Windows 7.
To use ktpass to generate a keytab file, run the following command:
ktpass.exe -out <keytab filename> -princ <service principal name> -mapuser <user account> [-pass <user account password>]-crypto <keys> -ptype <principal type>
The following table describes the command options:
Option
Description
-out
The file name of the Kerberos keytab file to generate as shown under the
KEY_TAB_NAME
column in the SPNKeytabFormat.txt file.
-princ
The service principal name displayed under the
SPN
column in the SPNKeytabFormat.txt file.
-mapuser
The Active Directory user account to associate with the SPN.
-pass
The password set in Active Directory for the Active Directory user account, if applicable.
-crypto
Specifies the key types generated in the keytab file.
Set to all to use all supported cryptographic types.
-ptype
The principal type. Set to KRB5_NT_PRINCIPAL.
When you run ktpass, you associate each node account and HTTP process account with the corresponding SPN in Active Directory. The following table shows the association between the accounts and the SPNs described in this article:
