i have RoundCube setup on a ubuntu 10.04 server, and it works perfectly when browsing to address.tld/roundcube

however I would like to be able to go to mail.address.tld

for this I have added the following virtual host config:

```
<VirtualHost mail.address.tld>
ServerAdmin webmaster@localhost
ServerName mail.address.tld/roundcube
DocumentRoot /var/www/roundcube
<Directory /var/www/roundcube>
    Options FollowSymLinks
    AllowOverride None
</Directory>
<Directory /var/www/roundcube>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

```

The Roundcube page is able to open however the PHP functions do not work correctly. I would like to resolve that.
