Password plugin error (chpasswd)
« on: April 03, 2012, 12:35:17 PM »
Hi friends,

I have a little problem with the password plugin. I see many people it is the same, i receive the error message "password could not be saved".  i´m  trying to do it with chpassword and in config.inc.php i have:
Code: [Select]
$rcmail_config['password_driver'] = 'chpasswd';
And in chpasswd.php:
Code: [Select]
function password_save($currpass, $newpass)
{
    $cmd = rcmail::get_instance()->config->get('password_chpasswd_cmd');
    $username = $_SESSION['username'];

    $handle = popen($cmd, "w");
    fwrite($handle, "$username:$newpass\n");

    if (pclose($handle) == 0) {
        return PASSWORD_SUCCESS;
    }
    else {
        raise_error(array(
            'code' => 600,
            'type' => 'php',
            'file' => __FILE__, 'line' => __LINE__,
            'message' => "Password plugin: Unable to execute $cmd"
            ), true, false);
    }

    return PASSWORD_ERROR;

I have checked the open tickets but i can´t find anything.

Anybody can help me?

It looks like the user who runs the script (most likely apache) doesn't have the permissions to run the sudo command.

It could make sense, but i allow user apache to execute chpasswd but still doesn´t work. Still i have the same error message in log  :(
This is the way i do it:
I execute visudo and add the line
Code: [Select]
apache  ALL=NOPASSWD: /usr/sbin/chpasswdalso execute
Code: [Select]
usermod -s /bin/bash apache
Any ideas?

Thanks for everything

Hmm, maybe RoundCube isn't running under apache, how do you have the users setup on the system?

Hello;

I just ran into this problem, and figured it out by looking at the Apache error log.

### log sample ###

sudo: sorry, you must have a tty to run sudo

### end log sample ###

What I needed was to edit sudoers and comment out the line which had 'requiretty'

I hope this helps.

Solution:

modify sudoers, use visudo, only add:

apache ALL=NOPASSWD: /usr/sbin/chpasswd
Defaults:apache !requiretty

don't change any lines
