[Samba] smbpasswd -m, changing account to a machine account.

I had a problem with
	smbpasswd -m

The man pages says:
       -m     This option tells smbpasswd that the account  being
               changed  is  a  MACHINE  account. Currently this is
               used when Samba is being  used  as  an  NT  Primary
               Domain Controller.

               This  option  is  only  available when running smb-
               passwd as root.

Before samba-2.2.8a the behaviour was as expected.
If I ran 'smbpasswd -m -a machine$' on an existing account
the account was reset and could be used as a machine account.
In samba-2.2.8a and in the current 2_2 branch in the cvs the
behaviour is different. The account will not be changed into a
machine account but stays as it was before, a user account.
This is a little bit confusing because trying to add a machine
to the domain failes with "Specified user already exists".

I appended a patch which could solve the problem. It changes
passdb.c to assure that local_password_change always
honors the LOCAL_TRUST_ACCOUNT flag. The current
cvs only uses it when adding an account.

It's not a bug but an annoying behaviour.

But why do you want such stupid things? Changing a user
account to a machine account doesn't make sense to me?

Well we use it to create a dummy account in our ldap tree to
keep all the machines separated from the users.
smbpasswd is used afterwards to setup the already
existing account. It might not be the most straight forward
way. But for historical reasons it grew like this.
In any case I'd expect the -m flag to work always, not only
during creation of a new account.
