[Samba] ERROR: Unable to fetch machine password

[Mike Box]

Samba 3.0.4 ...

I receive "ERROR: Unable to fetch machine password" from smbclient.

"Fetch machine password" from where?

This Samba is a member (security=domain) of a Windows 2003 domain.
When executing smbclient from within a script (Unix printer driver)
to route Unix (lp) print to shared desktop printer, the above message
is produced.  (The same script has worked for years for Samba 2.0.7 as
a member of a Windows NT domain.)

Thanks, in advance, for guidance in resolving this problem.
