You might need to do:

linuxserv:~ # useradd -M testmachine$

to create the machine account in the Unix password database (usu. 
/etc/passwd) before attempting to add it to the Samba password database. 
Note that the -M option prevents the creation of a home directory and 
other default files, and the $ is required for machine accounts. Note 
also when adding machine accounts to Samba, the $ is automatically 
appended so you should NOT include it. Likewise for users, you may need 
to do:

linuxserv:~ # useradd someuser

Now that being said, it's also possible to use LDAP for all of your 
authentication, which would eliminate the need for adding machine and 
user accounts to the Unix password database. Heck, it would elminate the 
need FOR a unix password database. Don't ask me how (as I've never done 
it), but a fellow by the name of John H. Terpstra has written an 
excellent book on the subject, see above. ;-)
