Alias redirect ERROR 403

I use

Code:

Alias /webmail /var/www/roundcube

to access roundcubemail. It seems I touched the wrong skrew, because now I get error 403 when I call http://www.domain.xyz/webmail (domain is located in /var/www/domain.xyz/web)
but I do not recall what I did...

The log says:

Code:

client denied by server configuration: /var/www/roundcube/

 

I solved this problem by adding a whole config. It's a mystery why I suddenly need to do this (before it worked with only the Alias line) but the config now looks like this:

Code:

# RoundCube alias and redirect functions
Alias /webmail /var/www/roundcube
<Directory /var/www/roundcube>
  Options +FollowSymLinks
  # This is needed to parse /var/www/roundcube/.htaccess. See its
  # content before setting AllowOverride to None.
  AllowOverride All
  order allow,deny
  allow from all

        <IfModule mod_php5.c>
                AddType application/x-httpd-php .php

                php_flag magic_quotes_gpc Off
                php_flag track_vars On
                php_flag register_globals Off
                php_value include_path .
        </IfModule>

</Directory>
