Apache permissions

There have been some reports on Apache setups giving grief to access the trell component, especially under Ubuntu. This guide tries to fix the 403-error.

The solution

Add

<Directory /usr/var/trell>
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

to the /etc/apache2/apache2.conf file.

Update 20140622: It may also be required to add the statement Satisfy Any to the section above. Your mileage may vary.
