[Samba] Permission denied

[malcolm]

I have a Windows 2003 server with a share
I try and mount a drive as follows :

cd ~
mkdir testsmb
smbmount //servername/sharename /home/myname/testsmb -o 
"credentials=/home/myname/smbpassword"
and everything seems OK
but a ls of testsmb gives
?--------- ? ?     ?      ? smbtest
you can cd to the directory but ls gives permission denied

If I use the Gnome GUI it works OK
This is RH FC4

thanks
