Using the machine account password in a session setup request

[samba learner]

Hi,

Is it possible to use the machine
name/machine-account-password  in a session-setup
request?

That is, if in the session setup request,

user name --> <my_machine_name>$
Hash of passwd sent to cli_establish_connection() -->
the hash recovered from the domain.machine.mac file by
using pdb_gethexpwd()

will cli_session_setup return successfully?

NOTE: This is Samba-2.0.7 and I intend to use this
session-setup to get the rpcclient utility running
without having to ask the username-passwd.

Thanks!
Regards.
