We use a Windows print server and until now it was possible to store the needed credentials in the KeyChain. By the first print, OS X asks for username and password with the possibility to remember it.
On all the machines we updated to macOS Sierra, the system asks for the credentials for each print:
The stored password is correct, and I only need to press "OK".
Is there a way to avoid the confirmation dialog (as on all the previous OS versions)?
