I'm trying to connect to a Windows network/printer and Ubuntu keeps asking for a username and password authentication. The problem is that the Windows network doesn't have any password authentication enabled. Before upgrading to 16.04 it's was working ok, without the need of password.

  • Can't you select anonymous user and select remember forever?

  • No. This option doesn't show up for me. (I'm on Ubuntu MATE)

  • Are you using the standard file manager in mate or a different one? And are you attempting to connect to a share and printer on a Windows pc?

  • If you are open file manager, click on network and select pc, I still receive anonymous user prompt in 16.04

  • I'm using the default file manager on Mate (Caja). I have othes windows PC's in this network that can access shared files (and the printer) without any password authentication.

I realized I just had to use my system password (that I use to login to Ubuntu)


Aside from the usual, "You need to put a password on your fileshares" response I will offer the following reply. More to the point, however, more modern versions of windows are starting to enforce the need for having a password. This is a good thing.

Following may be a post that has your answer. https://serverfault.com/questions/630631/how-to-make-samba-share-to-not-ask-for-password

I was thrown off by your mention of the printer. My comments are about connecting to a fileshare.

  • He just upgraded Ubuntu not Windows and was working on previous version. He is not setting up a samba share, he is connecting to his Windows share

  • Exactly. The problem must be my Ubuntu's present configuration.

After doing some research this issue appears to be fixed in samba version 4.3.9.

sudo apt-get update

sudo apt-get upgrade


sudo apt-get dist-upgrade

This should resolve your issue and allow you to click anonymous and remember forever choice.

If at 4.3.9, follow the guide on this website to mount Windows shares permanently.


  • My samba is already on 4.3.9 and my system is fully upgraded.

  • Caio, I added a link at the bottom to manually add the shares permanently. This should work but takes a little setup

  • Ok, I'll try it later ;)

Firstly, right click on your Windows 7 Computer icon and then select Properties. There, you shall find and right down your Computer's Name, e.g. «Alex-PC». That is the username that Ubuntu 16.04 is asking for.
Secondly, give as password your Ubuntu's 16.04 system password and voila, you are ready to go.

P.S.: Keep in mind that you must have disabled network need for password from your Windows 7 advanced network options.
