RoundCube Allow user to change password

[tobelyan]

Hi everyone,
i got a problem - well i am using RoundCube and my users can't change password,
so i am using ISP Manager, on CentOS 6
what i have done:
Edited this line: $rcmail_config['plugins'] = array();
to: $rcmail_config['plugins'] = array(‘password’);
and now i have an option about changing my password
but when i am trying to change it am getting an error something like" Can't save password"
i guess it's database problem, so maybe somebody can help me with this?

You need to configure the password plugin for your environment, read the README file in the password plugin folder.

sorry i am new, i don't understand what i should do, where to change,
like my database name is:  roundcubemail
database user: roundcube
pass: somepass

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
