[Bug 1572876] Re: After Samba upgrade can't access unpassworded windows share

[Pavlos Kairis]

I tried this with Ubuntu Mate 16.04 trying to access -> a winxp and win7
share. I did apt-get update/dist-upgrade and it brought in samba 4.3.9 I
added Ivan's 3 lines in [global] of smb.conf (see 2 posts above), I
entered userid & password and selected "Remember Forever" and I can
access the shares. The popup window is a bit annoying but at least now I
can access shares.

I will test with my 14.04 and 15.10 and report back.
