[Eric Dahnke]> How can I allow users to use the Administrator accounts on their

If you're logging in as a local user, the PDC shouldn't be involved at
all. This should always work. Even if you unplug from the network.
I suspect you are not talking about logins but about file service. If
you want to use Samba as a file server, you will have a problem, since
as you say Samba has a flat namespace for users. This is by design,
and Jeremy Allison, at least, thinks it is desirable. Luke Leighton
doesn't; he is trying to add multiple-domain awareness to Samba-TNG
using lookup tables. (I'm not sure of the status of this effort,
though I know it isn't complete.)
Meanwhile, I believe you are out of luck. You may have to go around
and rename all your local administrator accounts. Which is a PITA for
you and for all your little local administrators, but at least renaming
an account in NT is not very hard....
