Add a Network Printer to Mac OS X 10.6 (Snow Leopard)

Due to some changes that were made to the UF Network in the summer of 2012, Snow Leopard does not print to our systems “out of the box.”  However, getting Snow Leopard Macs to print in our environment is simple once a couple of configuration changes have been made to two files.

Changes to the /etc/smb.conf and /var/db/smb.conf files are required.  You must be a local administrator on the machine in order to make these changes.

Step 1:
Open a terminal window up, and edit the file /etc/smb.conf by issuing the command sudo nano /etc/smb.conf. Enter the administrator password when prompted.

Step 2:
Scroll down to the [global] section of the file, and add the following two lines:

 

Client ntlmv2 auth = yes
ntlm auth = no

Step 3:
Press control O (^O) to save the file, and press control X (^X) to exit the text editor.

 

Step 4:
Edit the /var/db/smb.conf file by issuing the command sudo nano /var/db/smb.conf.

 

Step 5:
Scroll down to the line that says ntlm auth = yes and change it to say ntlm auth = no.  Then use control O (^O) to save the file, and control X (^X) to exit the editor.
