  1. Start a command prompt.

  2. Enter the following command to generate the keytab file for the Universal DDI user account:

    ktpass -princ username@REALM -mapuser logon_name@REALM 
    -pass password -out my.tab -ptype krb5_nt_principal -crypto encryption
    Example: 
    ktpass -princ DNS/ns1.corpxyzexample.com@GSS.LOCAL -mapuser jsmith@GSS.LOCAL -pass 
    37Le37 -out ns1.keytab -ptype krb5_nt_principal -crypto RC4-HMAC-NT

    where:
    -princ = Kerberos principal. Note that this parameter is case-sensitive. Specifies the principal name for the NIOS-X Server or service in this format: DNS/ns1.corpxyzexample.com@GSS.LOCAL

  • DNS = Service name in uppercase format.
  • ns1.corpxyzexample.com = Instance in FQDN (fully-qualified domain name) format; this is the same as the DNS name of the NIOS-X Server.
  • GSS.LOCAL = The Kerberos realm in uppercase format. This must be the same as the AD domain name.
