Description:

A few days ago I upgraded the system and now I can't print anymore. Printing looks good in the first seconds and it seems as if the dox are sent over the network. Then a dialog window pops up reading "Authentication required for printing document "..."." The dialog contains a field "negotiate" and a checkbox "Remember password". It doesn't matter what I enter into the "negotiate" text box, none seems right, neither the local user's or root's passwd, nor the passwd of the account creds' passwd I'm supplied with. The only option that makes the dialog vanish is Cancel. A look into the printer queue then shows an entry reading "Tree connect failed (NT_STATUS_ACCESS_DENIED)".

A look into /etc/cups/printer.conf tells me that "AuthInfoRequired none" has changed to "AuthInfoRequired negotiate". When I stop cups and the change that entry back to "none", start cups, the same happens again: The dialog pops up and the entry in /etc/cups/printers.conf has been overwritten and reads "AuthInfoRequired negotiate" again.



Steps to reproduce:

-Add samba printer that requires authentication.
-Print a document
