Actually, "-l -c" ("-c" stands for "current user", even if a domain one).

Umm, sorry, Brian, but this is not true. The username in /etc/passwd
doesn't matter at all, and neither does the UID -- it's the SID field
that's important.

Not true. The name can be changed arbitrarily (in fact, the ntsec section
of the UG has examples of this).

Use "-d -u USERNAME" to add only the user USERNAME from the domain.
Or use "-c" to add the current (domain) user.
