samba - Mar 2009 - pdbedit's add machine option

Hi All,

I have been reading through "man pdedit".  I came across
the "-m" option:

        -m
           This option may only be used in conjunction with
           the -a  option.  It will  make  pdbedit to add
           a machine trust account instead of a user
           account (-u username will provide the machine name).

           Example: pdbedit -a -m -u w2k-wks


Not to ask too stupid a question, but why would you want
to have a "machine" account?  Would not the user account
suffice?

Confused,
-T

The Samba packages contain a book called: "The Oficial Samba-3 HOWTO and 
Reference Guide"

Look at Chapter 4: Domain Control
