Nother problem that cost me some life time and hair too I'd say. Fiddeling around with samba on Debian wheezy I created a share that should be public accesible. So we call it public. Yes I am an artist and genius when making up names. Anyways as we want the guest account to be allowed we put guest ok = yes inside the config part of the share. Also to be a bit more restrictive I also added valid users = +smbusers (Nother prove of my genuine artistry). The usaual path and other things found there...
