[Samba] Map multiple NT users to the same Unix user with tdbsam

I have an NTFS partition on an USB HDD mounted with uid=1000, gid=1000.
Several users should be able to backup to that partition via Samba shares.
They should be able to log in each with their own user/pass. I'd rather
not have a separate unix account (/etc/passwd) for each of them (plus
that runs into trouble with the uid==gid==1000 problem on the NTFS
partition; I'd rather not set the whole NTFS disk world-writeable to
circumvent that). And I'd really like to avoid ldap, sticking with tdbsam.
What I wish I could do was having multiple user/password combinations on
the Windows side and map them all to one user on the unix side.
username map looked like the solution, but isn't; quoting the
documentation: "... for user or share mode security, the username map is
applied prior to validating the user credentials." Thus AIUI all the
users would be required to share a password (that of the user they are
The only other thing I can think of is using share level security, and
giving every user one share he can use. Seems possible but suboptimal.
Having something like username map, but with it being applied after
credential validation would exactly solve my problem (if smbpasswd let
me create users absent from /etc/passwd).
Is there any way to achieve something like this? Anyone got another
solution for my scenario?
