Well first off I hope this isn't literal
<Directory “path to directory like /var/www/html/folder
Cause that won't fly.
Second what is the ownership/permissons of the directory the symlink is referancing? It will need to be something apache can read. If you don't know then issue a
ls -la /var/www/html/folder
and depending on your distro
chown -R apache:apache /var/www/html/folder
chown -R www:www /var/www/html/folder
check your /etc/passwd to find out which.
Or you could chmod to something apache can read, but not write. Stay away from 777.
