install the following:

  • Fedora/Redhat:
dnf install samba-common-tools samba system-config-printer-libs.noarch system-config-printer-udev.x86_64 system-config-printer-udev.x86_64 samba-krb5-printing krb5-devel krb5-libs krb5-workstation krb5-auth-dialog krb5-pkinit *samba*

The important parts here is

AuthInfoRequired username,password

in order to force the system to prompt with a username and a password

and USER must be replaced with a valid NCMM user

DeviceURI lpd://

[georgmar@bioteklin210 ~]$ cat /etc/samba/smb.conf

# See smb.conf.example for a more detailed config file or
# read the smb.conf manpage.
# Run 'testparm' to verify the config is correct after
# you modified it.
       workgroup = UIO
       security = user
       passdb backend = tdbsam
       printing = cups
       printcap name = cups
       load printers = yes
       cups options = raw
       client max protocol=SMB3

Important parts here:

  • workgroup set to UIO
  • client max protocol=SMB3

Restart the above services

sudo systemctl restart cups.service
sudo systemctl restart smbd.service

Make sure SELinux does not cause any troubles

sudo audit2allow  -a -M kotkot1
sudo semodule -i kotkot1.pp

Download Ricoh-MP_C4504ex.ppd from

replace USER with appropriate username

sudo lpadmin -x Ricoh
sudo lpadmin -E -U USER -p Ricoh -E -v lpd:// -m Ricoh-MP_C4504ex -P ./Ricoh-MP_C4504ex.ppd -L "Kopyrom" -o auth-info-required=username,password
sudo lpadmin -E -U USER -d ricoh
sudo cupsaccept -E -U USER ricoh
sudo cupsenable -E -U USER ricoh
lpr -E ./out
lpq -E

The big surprise here was that USIT uised the line printing protocol (ldp://) for linux instead of SMB. And of course they did not tell us

Additional steps:

We need tpo authenticate you against the UiO domain, and then print a test document, say a pdf.

  1. Authenticating against the UiO domain

1. open a terminal and type


it will as you your UiO password. Type it in the terminal.

This will authenticate you against the UiO domain but only for the first time, but will make the second step easier.

2. Maintaining the authentication: I don't know if there is such a panel in your desktop manager, but in Gnome there is the "Online accounts" in setting. And then the "Enterprise Login" is hidden at the bottom of the page under the three dots. Straight forward, enter


at the textbox that will open, make sure to click/check "Remember my password" and then type your password anywhere asked. Save, and you are done.

If 2. is not available, we have another route, but I will come upstairs tomorrow to show you: basically when you print the file there should be a dialog to prompt you to authenticate.

3. Print a file and then go to any Ricoh printer with your UiO id and pick up
