How to make access to samba folders with a password?

Question

Samba

I can't figure out why I can't access a folder shared with Samba (on ubuntu 12.04).
I added a user to Samba using smbpasswd I
also added a user to the sambashare group.
There is a folder with guest access, I can go there, I can write files.
And if I create and share a folder, for access with a password, it says "No access to ... Perhaps you do not have rights to connect to this resource" (I connect from the windows of the machine)
I rummaged through all the logs, records about unsuccessful authorization or something like that found. Please help
smb.conf

Answer 1

Added user to Samba using smbpasswd

Is the user really active?
