samba users can't be seen from client mashine

[murat can tuna]

Hi all,

I have an ubuntu server 9.10 and a fedora. I have configured smb.confs such that fedora or any other computer is gonna reach /home of ubuntu server. But the problem is i can not see samba users that i have created on ubuntu I mean fedora can not find or reach or resolve samba users that I have created on ubuntu.
I have mounted /home directory of ubuntu from fedora without any problem I can ping ubuntu or vice versa even this command works "smbclient -L <ipofubuntu> -Umuratcantuna" . Here is my two smb.conf files, do you have any idea what is the reason?

fedora:
