Autodiscover: DisplayName

[A Former User]

If i use as backend backendCombined with only CardDAV and CalDAV, it seems that i can’t get the FullName or DisplayName in autodiscover. If i add also BackendIMAP i found getting a DisplayName by using a SQL Query (using Roundcube in my special case):

define('IMAP_FROM_SQL_DSN', 'sqlite:/media/mount/db/roundcube.db');
define('IMAP_FROM_SQL_USER', '');
define('IMAP_FROM_SQL_PASSWORD', '');
define('IMAP_FROM_SQL_OPTIONS', serialize(array(PDO::ATTR_PERSISTENT => true)));
define('IMAP_FROM_SQL_QUERY', "select name, email from identities where email = '#username'");
define('IMAP_FROM_SQL_FIELDS', serialize(array('name', 'email')));
define('IMAP_FROM_SQL_EMAIL', '#email');
define('IMAP_FROM_SQL_FROM', '#name <#email>');
define('IMAP_FROM_SQL_FULLNAME', '#name');

Is there some similar way available also for autodiscover?

BTW: Also the servername can’t be defined. Would be nice if someone have a workaround for me…
