4 * expect driver
|
|
|
5 *
|
|
|
6 * Driver that adds functionality to change the systems user password via
|
|
|
7 * the 'expect' command.
|
|
|
8 *
|
|
|
9 * For installation instructions please read the README file.
|
|
|
10 *
|
|
|
11 * @version 2.0
|
|
|
12 * @author Andy Theuninck <gohanman@gmail.com)
|
|
|
13 *
|
|
|
14 * Based on chpasswd roundcubemail password driver by
|
|
|
15 * @author Alex Cartwright <acartwright@mutinydesign.co.uk)
|
|
|
16 * and expect horde passwd driver by
|
|
|
17 * @author Gaudenz Steinlin <gaudenz@soziologie.ch>
|
|
|
18 *
|
|
|
19 * Configuration settings:
|
|
|
20 * password_expect_bin => location of expect (e.g. /usr/bin/expect)
|
|
|
21 * password_expect_script => path to "password-expect" file
|
|
|
22 * password_expect_params => arguments for the expect script
|
|
|
23 * see the password-expect file for details. This is probably
|
|
|
24 * a good starting default:
|
|
|
25 * -telent -host localhost -output /tmp/passwd.log -log /tmp/passwd.log
