-/**
- * Change Password
- *
- * Plugin that adds a possibility to change password using a database
- * (Settings -> Password tab)
- *
- * @version 1.1
- * @author Aleksander 'A.L.E.C' Machniak <alec@alec.pl>
- * @editor Daniel Black
- *
- * Configuration Items (config/main.inc.php):
- * password_confirm_current - boolean to determine whether current password
- * is required to change password. Defaults to FALSE.
- * password_db_dsn - is the PEAR database DSN for performing the query. Defaults
- * to the default databse setting in config/db.inc.php
- * password_query - the SQL query used to change the password.
- * If the SQL query is a SELECT it will return an error message in a row if unsuccessful
- * If the SQL query is a UPDATE it will update a single row only.
- * An UPDATE where zero rows changed will be inteperated to be a wrong username/password
- * More than one row changed will be inteperated as an internal error
- * The query can contain the following macros that will be expanded as follows:
- * %p is replaced with the plaintext new password
- * %c is replaced with the crypt version of the new password, MD5 if available
- * otherwise DES.
- * %u is replaced with the username (from the session info)
- * %o is replaced with the password before the change
- * %h is replaced with the imap host (from the session info)
- * Escaping of macros is handled by this module.
- * Defaults to "SELECT update_passwd(%c, %u)"
- * To use this you need to define the update_passwd function in your
- * database.
- *
- * Example SQL queries:
- * These will typically need to define a function to change the password:
- *
- * 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
- * Uupdates 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
- *
