CUPS 403 Forbidden error

No matter what I change in my cups configuration file, it just won't work. Every time I try to access the administration pages or add a new printer, I get a 403 forbidden error.

Please look at my current config file and tell me where I'm going wrong.:confused:
Be gentle, I'm fairly new to Linux.

Code:

Are you trying to access the admin page from a different machine one the same network?

I've tried both. However, I only have three machines, so it's no big deal to add printers from my linux box. I get the 403 permission error when I go to port 631/admin from the server itself.

Part of my problem, I suspect, is that I may not have SAMBA configured properly. This is a bit overwhelming.

I doubt that the problem is related to samba, but maybe the way you have configured access permissions in cupsd.conf. This is part of my cupsd.conf

Code:

---

# Only listen for connections from the local machine.
#Listen localhost:631
Listen 192.168.1.126:631
Listen /var/run/cups/cups.sock

# Show shared printers on the local network.
Browsing On
BrowseOrder allow,deny
BrowseAllow all
BrowseAddress @LOCAL

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

# Restrict access to the server...
<Location />
  Order allow,deny
  Allow localhost
  Allow @LOCAL
</Location>

# Restrict access to the admin pages...
<Location /admin>
  Order allow,deny
  Allow @LOCAL
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Default
  Require user @SYSTEM
  Order allow,deny
  Allow @LOCAL
</Location>

I configured cups to only listen to the ip address allocated to the server and allowed machines on the local network to browse the printers, access the server, admin pages and configuration files. Hope you can use this as a guide to fix your problem.

Thank you for your prompt response. I'm getting closer. I was missing info in the admin section (as you suggested).
Now there appears to be some confusion with my certificate. when I navigate to part 631 it wants to take me to localhost.localdomain instead of my ip address. I get a security certificate warning that I'm trying to access an IP address but the certificate is for localhost.localdomain. I then get an error or I land on my default apache page.
I'll keep playing. Any ideas?
Thanks again for the help.

Solution posted by Daark.Child works for me. At the begining I got the same problem with the Error 403 Forbidden, but now it's solved to me.
