passwd chat

This string controls the "chat"
conversation that takes places between smbd
8 and the local password changing
program to change the user's password. The string describes a
sequence of response-receive pairs that smbd
8 uses to determine what to send to the
and what to expect back. If the expected output is not
received then the password is not changed.

This chat sequence is often quite site specific, depending
on what local methods are used for password control (such as NIS

Note that this parameter only is used if the parameter is set to yes. This sequence is
then called AS ROOT when the SMB password in the
smbpasswd file is being changed, without access to the old password
cleartext. This means that root must be able to reset the user's password without
knowing the text of the previous password. In the presence of
NIS/YP, this means that the must
be executed on the NIS master.

The string can contain the macro %n which is substituted
for the new password. The old password (%o) is only available when
has been disabled.
The chat sequence can also contain the standard macros
\n, \r, \t and \s to give line-feed, carriage-return, tab
and space. The chat sequence string can also contain
a '*' which matches any sequence of characters. Double quotes can
be used to collect strings with spaces in them into a single

If the send string in any part of the chat sequence is a full
stop ".", then no string is sent. Similarly, if the
expect string is a full stop then no string is expected.

If the parameter is set to yes, the chat pairs may be matched in any order, and success is determined by the PAM result, not any particular output. The \n macro is ignored for PAM conversions.

Example: "*Enter NEW password*" %n\n "*Reenter NEW password*" %n\n "*Password changed*"
