[Samba] login problem with domain users

[mahesh pawar]

Hi all,

I am using samba 3.0.23d on my linux machine. 
This machine is connected in a domain where all other users are using
domain username and password to login.
but with this username and password they are unable to login in samba. 
my smb.conf file is like following,


[global]
        workgroup = BSIL
        server string = Samba testing
        encrypt passwords = yes
        os level = 20
        security = ads
        netbios name = MDT506
[data]
        path = /export
        guest ok = yes
        writeable = yes
        browseable = yes
        guest only = yes

I want everyone(domain user , guest accounts and others without password
also) to access this share.


can anyone help me in this regard.

Regards,
Mahesh Pawar.
