Yes, but the original poster's problem was that his username was not in
the default domain.  Thus, your solution won't work.

This is not true.

Specifying both the username and the domain name results in extracting
just that one user from the domain (as can be plainly seen from the source
of mkpasswd.c).

It may be that the order of arguments matters, and that the correct way to
specify the username and the domain would be
	mkpasswd -u MY_USER_ID -d MY_DOMAIN >> /etc/passwd
but the point remains the same.

The last point is true, but, as far as I could see, was not disputed by
anyone.
