Using Seafile as an exclusive storage mechanism

Edit /etc/roundcubemail/config.inc.php and add the following lines, adjusting them to match your setup:

# Seafile
$config['fileapi_backend'] = 'seafile';
$config['fileapi_seafile_host'] = 'files.example.com';
$config['fileapi_seafile_ssl_verify_peer'] = false;
$config['fileapi_seafile_ssl_verify_host'] = false;
$config['fileapi_seafile_debug'] = false;

The next time you try to access Files in the Kolab web client, Kolab will attempt to authenticate towards Seafile with the same username / password combination as your account and use Seafile as storage.

Using Seafile as an add-on to the existing Kolab storage

Edit /etc/roundcubemail/config.inc.php and add the following lines, adjusting them to match your setup:

# Seafile
$config['fileapi_backend'] = 'kolab';
$config['fileapi_drivers'] = array('seafile');
$config['fileapi_seafile_host'] = 'files.example.com';
$config['fileapi_seafile_ssl_verify_peer'] = false;
$config['fileapi_seafile_ssl_verify_host'] = false;
$config['fileapi_seafile_debug'] = false;

In this configuration, an additional step is required to access Seafile. Chwala needs to be made aware of the additional storage. Access your Roundcube webmail and go to the Files component. Click on the gearbox icon and select Add additional storage. Fill in all the necessary details in the dialog box, and click on OK. A new Seafile folder will be made available, pointing at your Seafile library.

Enabling debug output

In case of errors, enable the debug logging for chwala in /etc/roundcubemail/config.inc.php by setting:

$config['fileapi_seafile_debug'] = true

…and inspect the logs in /var/log/chwala/

NOTE: You may have to logout and login again if you are in an existing roundcube session.
