vhost config file

Has anyone followed the Appache Configuring HTTP basic authentication? Where is the vhost configuration file located?

OK, I got it. Putting the security inside the area and removing Allow from all

For those looking, the location of the config file is /etc/apache2/sites-available

One thing to note. There is a maximum limit on the password (I think up to 8 chars) anything else after 8 chars is ignored.
I read a blog post stating that it has got to do with the way the passwords are stored in a file.

Could anyone please shed some light on this?
