Hello,

I'm not sure if this issue is a bug. I've asked on the users list and don't believe there's anyone on it, i've got no list traffic.

I use Roundcube 1.3.4 on a FreeBSD system.

I use postfix which gets it's authentication from dovecot imap server and goes to a MySQL database. I am now wanting to get roundcube's password plugin to be able to change a users password. In the password plugin configuration file I had this originally:

update virtual_users set password=CONCAT('{SHA512-CRYPT}', ENCRYPT (%p, CONCAT('$6$', SUBSTRING(SHA(RAND()), -16)))) WHERE user=%u;

This didn't work nor did it return any debug information. I then went in to MySQL directly and did this:

update virtual_users set password=CONCAT('{SHA512-CRYPT}', ENCRYPT ('PasswordGoesHere', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16)))) WHERE user='Username goes here';

Directly at the MySQL prompt this worked replaced user and password with values and it got returned correctly. I then did this with %p and %u as it appeared that not having them quoted was causing an error. Through none of this am I getting any kind of debug or log output:

update virtual_users set password=CONCAT('{SHA512-CRYPT}', ENCRYPT ('%p', CONCAT('$6$', SUBSTRING(SHA(RAND()), -16)))) WHERE user='%u';

I try to change the password and I get brought back to the same screen, no errors on the screen and nothing in a log, the password does not get changed.

Any suggestions or ways I can get some logging information?

Also, when doing the change at the MySQL prompt I got a warning, doing a show warnings revealed error 1287 that the ENCRYPT function is deprecated and to use AES_ENCRYPT instead. I tried replacing ENCRYPT with AES_ENCRYPT and that didn't work.

I've got debug and sql and imap debug all enabled. I've got the below sql schema for my virtual users table:

mysql> describe virtual_users; +------------------+----------------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +------------------+----------------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | domain_id | int(11) | NO | MUL | NULL | | | user | varchar(40) | NO | MUL | NULL | | | password | varchar(128) | NO | | NULL | | | uid | smallint(5) unsigned | NO | | 999 | | | gid | smallint(5) unsigned | NO | | 999 | | | quota | bigint(20) | NO | | 0 | | | active | tinyint(1) | NO | | 1 | | | allow_imap | tinyint(1) | NO | | 1 | | | last_login_ip | varchar(16) | YES | | NULL | | | last_login_date | datetime | YES | | NULL | | | last_login_proto | varchar(5) | YES | | NULL | | +------------------+----------------------+------+-----+---------+----------------+ 12 rows in set (0.00 sec)

The passwords are done as sha512-crypt hashes. Here's my current password/config.inc.php file:

$cat config.inc.php <?php $config['password_driver'] = 'sql'; // Determine whether current password is required to change password. $config['password_confirm_current'] = true; // Require the new password to be a certain length. $config['password_minimum_length'] = 10; // Require the new password to contain a letter and punctuation character $config['password_require_nonalpha'] = true; // Enables logging of password changes into logs/password $config['password_log'] = true; // Comma-separated list of login exceptions for which password change // will be not available (no Password tab in Settings) $config['password_login_exceptions'] = null; // Array of hosts that support password changing. // Listed hosts will feature a Password option in Settings; others will not. // Example: array('mail.example.com', 'mail2.example.org'); // Default is NULL (all hosts supported). $config['password_hosts'] = null; // Enables saving the new password even if it matches the old password.

Suggestions welcome.
