I'm trying to setup Samba on a Linux Mint 17.3 install.  My /etc/samba/smb.conf file is at: http://pastebin.com/FvaK7Yq5When I try to access the share \\192.168.1.2\jezhome, I use the username WORKGROUP\jez and the correct passsword, yet in the Samba logfile I get the message guest user (from session setup) not permitted to access this share (jezhome).  But why is it trying to access the share as a guest user?  I don't get it.  There is nothing in there about the jez user I am trying to log in as.  I tried clearing these credentials in Windows and logging in again but I get the same deal.  Any ideas?
Why does Samba insist on logging on as a guest user?
samba
this would be consistent with unsuccessful authentication attempt?# This option controls how unsuccessful authentication attempts are mapped# to anonymous connections   map to guest = bad userplease post logfile showing your authentication succeeding or otherwise
