You must also make sure that your new Samba user is allowed to read and write to the defined Samba shares.
The O'Reilly Samba book is available for free downloading and you are advised to read that one, keeping it around as a printed copy for reference.
The OP didn't indicate much on what kind of share is being offered. The directory being shared has Unix ownerships & permissions which samba needs to map from Windows credentials. A lot depends on the type of service that samba offers, which isn't indicated.
The default is the "Security = Users" security mode. The smbpasswd command will create a samba user and windows password hash entry in /etc/samba/smbpasswd. To create a document on a share with the permissions of the user, the user needs to be in /etc/passwd as well. You would use this if the server is running on a desktop where you have an account. A [profiles] or [users] share works best for this.
