SMB share in-accessible from any PC, mac, android

I used to share directories from Ubuntu 12 to all other PCs on network, but since I clean-installed Ubuntu 13.1, shares are created and visible but they are in-accessible form the other machines

When I access this from OS X using password, authentication fails.

When I login with guest user I get share listing:

But I cannot access any of them:

Problem is consistent when I access the share across OS X, windows and Android. How do I debug it?

Here's smb.log

process_usershare_file: stat of /var/lib/samba/usershares/fxshare failed. Permission denied

I had the same issue and managed to solve it. It comes from the fact that the samba users must be declared with :

sudo smbpasswd -a fx

(replace fx with any user you would like to allow)
