I've seen the -A option for smbclient; here is the manpage that may help:
This option allows you to specify a file from which to read the
username and password used in the connection. The format of the file is
username = <value>
password = <value>
domain = <value>
Make certain that the permissions on the file restrict access
from unwanted users.
