passwd chat (G) 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 passwd program 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 etc). Note that this parameter only is only used if the unix password sync 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 passwd program must be executed on the NIS master. The string can contain the macro %n which is substituted for the new password. 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 string. 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 pam password change 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. See also unix password sync, passwd program , passwd chat debug and pam password change. Default: passwd chat = *new*password* %n\\n *new*password* %n\\n *changed* Example: passwd chat = "*Enter OLD password*" %o\\n "*Enter NEW password*" %n\\n "*Reenter NEW password*" %n\\n "*Password changed*"
