smbpasswd delete users

[CAE Samba Admin]

Hello,

	smbpasswd seems to be missing a rather key function...  Is it
still undocumented or can smbpasswd delete users from the smbpasswd file.
Is this functionality left out on purpose?  I have the need to delete
users out of the file, as I assume most people do.  However, besides the
inconvienence of using text editors/filters, I have concerns about one of
these programs editing the smbpasswd file while samba is trying to access
it or someone is changing a password.  Do you plan on implementing a
delete function to smbpasswd very soon?  If not, how do I go about locking
the smbpasswd file?
