ktpass with principal name different than domain controller domain

[Celia Clark]

Hi,

I am trying to do the following:

ktpass -princ HTTP/user.domain.com at DOMAIN.COM mapuser user -pass password01.

The command is run on a domain controller with a different domain than what
is specified in the service name, e.g. DOMAIN2.COM.

Is this possible?

Many thanks,

Celia
