Hi  Rowland,

Thanks for the help.	

Could you please let me know what would  be the passwd database if I update my smb.conf. 

I have created the user locally and in samba using the steps given by you. And it seems it's working fine. 

The authentication is successful, but I was wondering why it was working in earlier version without adding user in samba database.

I'm having around 100+ users/share and the authentication is share level, do I need to add all the users again in the samba database ? can you please comment on these as well. Thank you.

OK, what you seem to be trying to set up is a standalone server with only passworded user access.

Can I suggest you alter smb.conf to this:

        # Change 'WORKGROUP' below to whatever
        # you want your workgroup to be called.
        workgroup = WORKGROUP
        server string = Samba on AIX
        log file = /var/log/samba/%m.log
        log level = 2
        max log size = 1000

        comment = All Printers
        path = /usr/spool/samba
        printable = Yes
        browseable = No

        comment = Temporary file space
        path = /tmp
        read only = No

Your users will need to exist in /etc/passwd and also be Samba users, you can do this by running (as root):

smbpasswd -a USERNAME

You will be asked for a password for the user (twice) and then the user will be added to Samba's database

You will also need to run (again as root):

smbpasswd -e USERNAME

You can find more info on this here:


You do not need to run winbind on a standalone server, only 'smbd' & 'nmbd'

Any user that needs to connect to the shares, will need to be both a Unix and Samba user on the standalone server, they will also have to use the Samba users password.
