Password change under NT

[Greg Roberts]

Hi all. I'm currently having problems with changing passwords under NT and
having this new password being stored in /etc/yp/passwd and smbpasswd.

Here are the entries in my smb.conf file:

  encrypt passwords = yes
  smb passwd file = /usr/local/daemon/samba/private/smbpasswd
  unix password sync = yes
  passwd program = /usr/bin/yppasswd %u
  passwd chat = *Old*password* %o\n *New*password* %n\n *Retype*password*
%n\n *changed*
  log level = 3
  passwd chat debug = yes

Here's the entries made in the log file when I hit <return> to update the
password:

I'm using the CVS source of Samba (pre-3.0.0 - I grabbed it around
mid-late April) and it's running under Digital Unix 4.0E. 

Any ideas?
