Generate the Keytab Files at Node Level

Generate the Keytab Files at Node Level

When you run ktpass to generate the keytab files at the node level, you associate each Kerberos principal user account with the corresponding SPN in Active Directory.
The following table shows the association between the Kerberos principal user accounts and the SPNs shown in the example SPNKeytabFormat.txt file:
User Account
Keytab Type
Service Principal Name
nodeuser01
NODE_SPN
isp/node01/InfaDomain/COMPANY.COM
httpuser01
NODE_HTTP_SPN
HTTP/US001DEV.company.com@COMPANY.COM
nodeuser02
NODE_SPN
isp/node02/InfaDomain/COMPANY.COM
httpuser02
NODE_HTTP_SPN
HTTP/US005DEV.company.com@COMPANY.COM
You also create a keytab for the LDAP bind user account that is used to access and search Active Directory during LDAP synchronization.
  1. Create a keytab file for the Kerberos principal user account that you created for each node in Active Directory.
    Copy the keytab file name from the
    KEY_TAB_NAME
     column in the SPNKeytabFormat.txt file. Copy the service principal name from the
    SPN
     column in the SPNKeytabFormat.txt file.
    The following example creates a keytab file for a Kerberos principal user account named nodeuser0:
    ktpass.exe -out node01.keytab -princ isp/node01/InfaDomain/COMPANY.COM -mapuser nodeuser01 -crypto all -ptype KRB5_NT_PRINCIPAL
  2. Create a keytab file for each HTTP process Kerberos principal user account that you created in Active Directory.
    If the domain uses Kerberos cross realm authentication, the principal user account can exist in any Kerberos realm the domain uses.
    Copy the keytab file name from the
    KEY_TAB_NAME
     column in the SPNKeytabFormat.txt file. Copy the service principal name from the
    SPN
     column in the SPNKeytabFormat.txt file.
    The following example creates a keytab file for a Kerberos principal user account named httpuser01:
    ktpass.exe -out webapp_http.keytab -princ HTTP/US001DEV.company.com@COMPANY.COM -mapuser httpuser01 -crypto all -ptype KRB5_NT_PRINCIPAL
  3. Create a keytab for the LDAP bind user account that is used to access and search Active Directory during LDAP synchronization.
    Structure the value for the -princ option as <principal name>@<KERBEROS REALM>. Include the name of the LDAP configuration for the Active Directory server in the keytab file name. Structure the keytab file name as follows: <Active Directory LDAP configuration_name>.keytab.
    The following example creates a keytab file for a service principal user account named ldapuser:
    ktpass.exe -out ActiveDirectoryServer1.keytab -princ ldapuser@COMPANY.COM -mapuser ldapuser -crypto all -ptype KRB5_NT_PRINCIPAL
