I've been reading and have been stuck for days. Using system-config-samba, I am only able to access shares that have a valid username attached to them (Edit Samba Share > Access > Only allow access to specific users > kid1000000 'checked'). Doing this, I can login using my kid100000 credentials just fine.

If I select "Allow access to everyone," browsing to that directory in nautilus returns an error: "Unable to mount location."

Thank you for your help.
