Comment 45 for bug 510059

Addendum: I have now discovered something interesting enlightening this problem. When I try Linux Mint 17 XFCE from usb (without installing to computer) I am able to mount smb inside Thunar (smb://XXX.XXX.XX/XXX). I just have to write username, domain and password once. When I install the same system to the same computer the username-domain-password prompt keeps reappering without mounting the folder.
