.htaccess and .htpasswd files in symbolic link directories.

[tarndt]

I have a symbolic link in one of my accounts created in ISPConfig:

So in
/home/www/web8
I have:
web -> /var/www/html/dealer/

Question is...How do I password protect this directory. Because the directory is owned by another user, it does not show in Web_FTP.
So I password protect another folder, and modified the .htaccess file and moved to the /var/www/html/dealer folder. This however returns a 500 Internal Server Error. Ownership of the .htacess and .htpasswd files are associated with the web8 user. I have also tried specifying the .htpasswd as both the symbolic link and the actual directory from within the .htaccess file. Any suggestions?
