Personally, I think this is the best idea of all, but of course, I have
no way of knowing how difficult this would be to accomplish since it is
samba that connects with the net rpc vampire and the concept of putting
the hashed password into a file is not exactly a secure one. Perhaps we
should bugzilla it as a feature request.

Anyway, this is the procedure I used to 'migrate' my /etc/passwd,
/etc/group/ /etc/services /etc/protocols /etc/hosts into ldap and I
found it extremely useful, editable and repeatable which allowed me to
wipe out my ldap db's and start over until I got exactly what I wanted
from the net rpc vampire - MANY MANY tries.
