I have setup a CUPS server with the web interface. Sadly I'm unable to add a printer by doing the following steps:

• Browser (REMOTE_SERVER_IP:631)


• Administration tab


• Local Printers


• HP Printer (HPLIP)


• Connection


• Add Printer (name and all the good stuff)


• Select model


• Select Driver


• Error

At this point I get the message: Unable to add printer: Unauthorized. My configuration file looks like this:

# Disable cups internal logging - use logrotate instead

MaxLogSize 0



# Log general information in error_log - change "warn" to "debug"

# for troubleshooting...

LogLevel warn

#PageLogFormat



Listen /run/cups/cups.sock

Listen 0.0.0.0:631

Port 631

I'm using the following Dockerfile to build and start the whole thing. I also provide a new user inside the image.

What am I missing?

Maybe you already fixed this but I had the same problem. Solved it by changing "Order deny,allow" to "Order allow,deny" and remove all Authentication stuff.

This is my configuration file:

#

# Configuration file for the CUPS scheduler.  See "man cupsd.conf" for a

# complete description of this file.

#



# Log general information in error_log - change "warn" to "debug"

# for troubleshooting...

LogLevel warn

PageLogFormat



# Deactivate CUPS' internal logrotating, as we provide a better one, especially

# LogLevel debug2 gets usable now

MaxLogSize 0



# Only listen for connections from the local machine.

Listen 631

Listen /var/run/cups/cups.sock



# Show shared printers on the local network.
