+ 2.5. DirectAdmin Control Panel (directadmin)
+ --------------------------------------------
+
+ You can specify which host to connect to via 'password_directadmin_host' (don't
+ forget to use tcp:// or ssl://) and what port via 'password_direactadmin_port'.
+ The password enforcement with plenty customization can be done directly by
+ DirectAdmin, please see http://www.directadmin.com/features.php?id=910
+ See config.inc.php.dist file for more info.
+
+
+ 2.6. cPanel (cpanel)
+ --------------------

+ interface. See config.inc.php.dist file for more info.
+
+
+ 2.7. XIMSS/Communigate (ximms)
+ ------------------------------
+
+ You can specify which host and port to connect to via 'password_ximss_host'
+ and 'password_ximss_port'. See config.inc.php.dist file for more info.
+
+
+ 2.8. Virtualmin (virtualmin)
+ ----------------------------
+
+ As in sasl driver this one allows to change password using shell
+ utility called "virtualmin". See drivers/chgvirtualminpasswd.c for
+ installation instructions. See also config.inc.php.dist file.
+
+
+ 2.9. hMailServer (hmail)
+ ------------------------
+
+ Requires PHP COM (Windows only). For access to hMail server on remote host
+ you'll need to define 'hmailserver_remote_dcom' and 'hmailserver_server'.
+ See config.inc.php.dist file for more info.
+
+
+ 2.10. PAM (pam)
+ ---------------
+
+ This driver is for changing passwords of shell users authenticated with PAM.
+ Requires PECL's PAM exitension to be installed (http://pecl.php.net/package/PAM).
+
+
+ 2.11. Chpasswd (chpasswd)
+ -------------------------
+
+ Driver that adds functionality to change the systems user password via
+ the 'chpasswd' command. See config.inc.php.dist file.
+
+ Attached wrapper script (chpass-wrapper.py) restricts password changes
+ to uids >= 1000 and can deny requests based on a blacklist.
+
+
+ 2.12. LDAP - no PEAR (ldap_simple)
+ -----------------------------------
+
+ It's rewritten ldap driver that doesn't require the Net_LDAP2 PEAR extension.
+ It uses directly PHP's ldap module functions instead (as Roundcube does).
+
+ This driver is fully compatible with the ldap driver, but
+ does not require (or uses) the
+ $rcmail_config['password_ldap_force_replace'] variable.
+ Other advantages:
+ * Connects only once with the LDAP server when using the search user.
+ * Does not read the DN, but only replaces the password within (that is
+ why the 'force replace' is always used).
+
+
+ 2.13. XMail (xmail)
+ -----------------------------------
