Well, you *do* need an entry for your domain user.  That's accomplished
with "mkpasswd -d -u YOURUSERNAME" (which will only query the PDC for
YOURUSERNAME, not list all users).  I'm no security expert, but I think
there's enough local information that "mkpasswd -l -c" ("-c" stands for
"current user") works too (it doesn't query the PDC).

Yes.  You only need the groups that your domain user belongs to.  Since
I'm not in a domain, I don't know how to get a list of those, but I'm sure
someone here will respond with this info.

Using the "-g" flag to mkgroup will query the PDC for those groups
individually, which is *much* faster.  Omitting the "-g" (or the "-u" for
mkpasswd) will query the domain for all groups (users), which is what I
wrote about below.

Huh?  The domain users/groups live on the PDC, which is one machine.
Unless you mean that users and groups are constantly added and deleted?

But you're right, if you're the only user on the machine, "mkpasswd -d" is
overkill.  "mkpasswd -d -u YOURUSERNAME" isn't.
