samba - Apr 2006 - samba-3.0.22 on debian etch, fchmod_acl : Operation not supported

Hi All!

I`ve got a problem with samba-3.0.22 on Debian etch. Here is my
setting for shared directory:

[global]
        #[snip]
        # Auth options
        security = user
        encrypt passwords = true
        passdb backend = tdbsam guest
        map to guest = Bad User
        username map = /etc/samba/smbusers
        guest account = nobody
        invalid users = root
        password level = 2
        unix password sync = yes
        passwd program = /usr/bin/passwd %u
        passwd chat = *Enter\snew\sUNIX\spassword:* %n\n
*Retype\snew\sUNIX\spassword:* %n\n .
        #[snip]
[private]
        comment = [ private stuff ]
        path = /srv/samba/private
        browseable = yes
        guest ok = no
        read only = yes
        valid users = @private
        write list = @private
        force group = private
        hide dot files = yes
        #hide special files = yes
        hide unreadable = yes
        create mask = 0660
        directory mask = 0770
        force create mode = 0660
        force directory mode = 0770
        vfs object = audit
        preexec = sh -c 'cat /etc/samba/%S.motd | /usr/bin/smbclient
-M %m -I %I' &


That setup works before, but now I can`t copy files from WinXP into
this folder with following error message:

Apr 27 23:22:03 c3po smbd_audit[22923]: connect to service private by user vofka

What I need to do to get my setup working as before ?

Thanks
