[Samba] [homes] no accessible

[David Rigler]

On a server "linuxbox" using ADS security in a Windows 2003 Active 
directory, part of smb.conf is ...

[srvbackup]
        force user = sambaa
        writeable = yes
        valid users = ADS-Name+Administrator,ADS-Name+dave
        path = /var/spool/samba/sambashares/srvbackup

[homes]
        browseable = no
        writeable = yes

from an XP professional client, srvbackup is usable but i cannot access 
my home.
error dialog shows "\\linuxbox\dave is not accessible"

any ideas ??
