thank you.

if there's anyone else that feels this way, plese SAY SO.  if you don't,
samba will end up staying in the dark ages.

yes, .  it's a pain.  it's something to have to consider / deal with.  or

or use a mapping table to map NT names to <=8 unix usernames.

or restrict ann NT users to <=8 chars too.
