External user authentication

Authenticate user login against FTP, IMAP or SMB.

Configuration

IMAP

Add the following to your config.php:

'user_backends' => array(
    array(
        'class' => 'OC_User_IMAP',
        'arguments' => array(
            '{127.0.0.1:143/imap/readonly}',
        ),
    ),
),

This connects to the IMAP server on localhost.

Read the imap_open PHP manual page to learn more about the allowed parameters.
