|
|
|
1. Configuration
|
|
----------------
|
|
|
|
Copy config.inc.php.dist to config.inc.php and set the options as described
|
|
within the file.
|
|
|
|
|
|
2. Drivers
|
|
----------
|
|
|
|
Password plugin supports many password change mechanisms which are
|
|
handled by included drivers. Just pass driver name in 'password_driver' option.
|
|
|
|
|
|
2.1. Database (sql)
|
|
-------------------
|
|
|
|
You can specify which database to connect by 'password_db_dsn' option and
|
|
what SQL query to execute by 'password_query'. See main.inc.php.dist file for
|
|
more info.
|
|
|
|
Example implementations of an update_passwd function:
|
|
|
|
- This is for use with LMS (http://lms.org.pl) database and postgres:
|
|
|
|
CREATE OR REPLACE FUNCTION update_passwd(hash text, account text) RETURNS integer AS $$
|
|
DECLARE
|
|
res integer;
|
|
BEGIN
|
|
UPDATE passwd SET password = hash
|
|
WHERE login = split_part(account, '@', 1)
|
|
AND domainid = (SELECT id FROM domains WHERE name = split_part(account, '@', 2))
|
|
RETURNING id INTO res;
|
|
RETURN res;
|
|
END;
|
|
$$ LANGUAGE plpgsql SECURITY DEFINER;
|
|
|
|
- This is for use with a SELECT update_passwd(%o,%c,%u) query
|
|
Updates the password only when the old password matches the MD5 password
|
|
in the database
|
|
|
|
CREATE FUNCTION update_password (oldpass text, cryptpass text, user text) RETURNS text
|
|
MODIFIES SQL DATA
|
|
BEGIN
|
|
DECLARE currentsalt varchar(20);
|
|
DECLARE error text;
|
|
SET error = 'incorrect current password';
|
|
SELECT substring_index(substr(user.password,4),_latin1'$',1) INTO currentsalt FROM users WHERE username=user;
|
|
SELECT '' INTO error FROM users WHERE username=user AND password=ENCRYPT(oldpass,currentsalt);
|
|
UPDATE users SET password=cryptpass WHERE username=user AND password=ENCRYPT(oldpass,currentsalt);
|
|
RETURN error;
|
|
END
|
|
|
|
Example SQL UPDATEs:
|
|
|
|
- Plain text passwords:
|
|
UPDATE users SET password=%p WHERE username=%u AND password=%o AND domain=%h LIMIT 1
|
|
|
|
- Crypt text passwords:
|
|
UPDATE users SET password=%c WHERE username=%u LIMIT 1
|
|
|
|
- Use a MYSQL crypt function (*nix only) with random 8 character salt
|
|
UPDATE users SET password=ENCRYPT(%p,concat(_utf8'$1$',right(md5(rand()),8),_utf8'$')) WHERE username=%u LIMIT 1
|
|
|
|
- MD5 stored passwords:
|
|
UPDATE users SET password=MD5(%p) WHERE username=%u AND password=MD5(%o) LIMIT 1
|
|
|
|
|
|
2.2. Cyrus/SASL (sasl)
|
|
----------------------
|
|
|
|
Cyrus SASL database authentication allows your Cyrus+Roundcube
|
|
installation to host mail users without requiring a Unix Shell account!
|
|
|
|
This driver only covers the "sasldb" case when using Cyrus SASL. Kerberos
|
|
and PAM authentication mechanisms will require other techniques to enable
|
|
user password manipulations.
|
|
|
|
Cyrus SASL includes a shell utility called "saslpasswd" for manipulating
|
|
user passwords in the "sasldb" database. This plugin attempts to use
|
|
this utility to perform password manipulations required by your webmail
|
|
users without any administrative interaction. Unfortunately, this
|
|
scheme requires that the "saslpasswd" utility be run as the "cyrus"
|
|
user - kind of a security problem since we have chosen to SUID a small
|
|
script which will allow this to happen.
|
|
|
|
This driver is based on the Squirrelmail Change SASL Password Plugin.
|
|
See http://www.squirrelmail.org/plugin_view.php?id=107 for details.
|
|
|
|
Installation:
|
|
|
|
Change into the drivers directory. Edit the chgsaslpasswd.c file as is
|
|
documented within it.
|
|
|
|
Compile the wrapper program:
|
|
gcc -o chgsaslpasswd chgsaslpasswd.c
|
|
|
|
Chown the compiled chgsaslpasswd binary to the cyrus user and group
|
|
that your browser runs as, then chmod them to 4550.
|
|
|
|
For example, if your cyrus user is 'cyrus' and the apache server group is
|
|
'nobody' (I've been told Redhat runs Apache as user 'apache'):
|
|
|
|
chown cyrus:nobody chgsaslpasswd
|
|
chmod 4550 chgsaslpasswd
|
|
|
|
Stephen Carr has suggested users should try to run the scripts on a test
|
|
account as the cyrus user eg;
|
|
|
|
su cyrus -c "./chgsaslpasswd -p test_account"
|
|
|
|
This will allow you to make sure that the script will work for your setup.
|
|
Should the script not work, make sure that:
|
|
1) the user the script runs as has access to the saslpasswd|saslpasswd2
|
|
file and proper permissions
|
|
2) make sure the user in the chgsaslpasswd.c file is set correctly.
|
|
This could save you some headaches if you are the paranoid type.
|
|
|
|
|
|
2.3. Poppassd/Courierpassd (poppassd)
|
|
-------------------------------------
|
|
|
|
You can specify which host to connect to via 'password_pop_host' and
|
|
what port via 'password_pop_port'. See config.inc.php.dist file for more info.
|
|
|
|
|
|
2.4. LDAP (ldap)
|
|
----------------
|
|
|
|
See config.inc.php.dist file. Requires PEAR::Net_LDAP2 package.
|
|
|
|
|
|
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)
|
|
--------------------
|
|
|
|
You can specify parameters for HTTP connection to cPanel's admin
|
|
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)
|
|
-----------------------------------
|
|
|
|
Driver for XMail (www.xmailserver.org). See config.inc.php.dist file
|
|
for configuration description.
|
|
|
|
|
|
3. Driver API
|
|
-------------
|
|
|
|
Driver file (<driver_name>.php) must define 'password_save' function with
|
|
two arguments. First - current password, second - new password. Function
|
|
should return PASSWORD_SUCCESS on success or any of PASSWORD_CONNECT_ERROR,
|
|
PASSWORD_CRYPT_ERROR, PASSWORD_ERROR when driver was unable to change password.
|
|
Extended result (as a hash-array with 'message' and 'code' items) can be returned
|
|
too. See existing drivers in drivers/ directory for examples.
|
