[Samba] Beginner setting up samba: NT_STATUS_LOGON_FAILURE

[Thomas Hahn]

Hello,
I am trying to set up samba on this host and testing it locally
is giving me headaches right away.

tom at hversa:~:~$ smbclient -L localhost -U%
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.8]

        Sharename       Type      Comment

        homes           Disk      Home Directories
        print$          Disk      Printer Drivers
        IPC$            IPC       IPC Service (hversa server)

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.4.8]

        Server               Comment
        ---------            -------
        HVERSA               hversa server

        Workgroup            Master
        ---------            -------
        DERU_WICO001         OCHENTA
        WORKGROUP            HVERSA

So, there is sth. configured, BUT:

tom at hversa:/var/log/samba$ smbclient //hversa/tom -d 3
lp_load_ex: refreshing parameters

I have googled for the NT_STATUS_LOGON_FAILURE but this didn't help me.

Any hints please ...

Thanks Thomas
