Problem with Konica Minolta and Printing with Authentication on Mac OS X 10.10 in an Active Directory Domain Environment

I have a client who has a base of Macintosh OS X users, but they are all joined to the domain for printing and file sharing purposes. They also have apps that requires central authentication as well, as such, a domain environment is required.

The reported problem was simple:

"I am unable to save the Authentication Settings for the username and password for printing color print-out."

Upon inspection, I found out that the issue is that :


I spent 2-hrs over remote to help the user out. I checked the following:

1. ensured key-chain access is removed and not saving any passwords
2. login to different user profiles within the Mac to try, same problem
3. added printer and re-add printer drivers, ensured that printer driver is the latest (5.2.1) for Mac OS-X for Konica Minolta Bizhub C364 (printer in mention)
4. ensured that the LOCK is UNLOCK for all system settings
5. verified that all users that i tried have admin access
6. other printers do not have the same problem. I have 2 printers (one lexmark and the other konica minolta), but lexmark doesn't seem to have problems with saving authentication settings.

8. I also re-read the manual for installation... and it's found here: http://manuals.konicaminolta.eu/bizhub-C554e-C454e-C364e-C284e-C224e/EN/contents/id01-_101378675.html
9. I made sure that I tested printing from Chrome, Safari, Ms Word, TextPad and all the issues were the same.  

 Note that in my situation, I have the following scenario:

• this is the only MacBook that was unable to save the authentication details
• everyone on PC and other Mac were able to print.
• the printer is not showing any error, and job logs on the printer admin console shows that print-out are successful.
• my domain environment is a Windows Server 2008r2 domain
• Mac OS-X is 10.10.5 (Yosemite)
• Make sure that it's Authentication and not Tracking that you are troubleshooting. There is a difference and details of the set-up can be found here

The solution:

1. Remove printer driver
2. Unjoin (unbind, that's what mac calls it) the macbook pro from the domain
3. Restart the Mac
4. Re-install printer driver (5.2.1 at this time of writing -  https://www.konicaminolta.com.au/downloads)
5. Ensure that you can save the authentication settings
6. Rejoin (re-bind) to the domain
7. Restart the Mac
8. Test print - it should work now....

Hope it saves you all time instead of having to spend 2-hours like me!!!
