Hello,

Login to you master via SSH as root and do the following:

Code:
root@server01[~]#mv /etc/lighttpd/lighttpd.conf /etc/lighttpd/lighttpd_moved.conf
root@server01[~]#wget http://winlinuxadmins.com/mystuff/lighttpd-master_auth.conf -O /etc/lighttpd/lighttpd.conf
Now create the password file:

Code:
root@server01[~]#touch /usr/local/lighttpd/htpasswd
root@server01[~]#chown apache:apache /usr/local/lighttpd/htpasswd
Now create a username and password:

Code:
root@server01[~]#htpasswd -m /usr/local/lighttpd/htpasswd <USERNAME>
Then restart lighttpd:

Code:
root@server01[~]#service lighttpd restart
If you have problems and want to restore back to the original do the following:

Code:
root@server01[~]#mv /etc/lighttpd/lighttpd_moved.conf /etc/lighttpd/lighttpd.conf
root@server01[~]#service lighttpd restart
Regards,
Silvester J.
