Issue with Cups and https

Hi,
I am having an issue on my home network with my server and cups. I have cupsd.conf configured to allow my laptop (the server and laptop have fixed IP's) to administer the cups configuration remotely. The problem I run in to is that whenever I try to save a change to the config file via the cups web interface, it tries to redirect me to "https" rather than "http". Because this is my home network I am not concerned with encryption when it comes to printing. Below is my cupsd.conf file. I thought that by setting "Encryption Required" to "Encryption Never" it would take care of the problem but apparently not.

This is running on Slackware 21.1. Any ideas as to how to correct this?

Code:

LogLevel info
SystemGroup sys root
# Allow remote access
Port 631
Listen /var/run/cups/cups.sock
# Share local printers on the local network.

BrowseOrder allow,deny

Never mind. I was able to correct the problem by adding a line to the cupsd.conf file:

Code:

# Default authentication type, when authentication is required…
DefaultAuthType Basic

to

Code:

# Default authentication type, when authentication is required…
DefaultAuthType Basic
DefaultEncryption IfRequested
