I miss smbfs: cifs doesn't work as expected

[Nico Sabbi <Nicola Sabbi poste it>]

Hi,
with another distribution I could mount an SMB share as my user
(passing different credentials to mount.smbfs)
in such a manner that on my pc the mounted files appeared
to belong to my user.
The /etc/fstab entry was:

//server/dir /home/nico/dir smbfs 
noauto,users,rw,noexec,username=MYUSERNAME,password=MYPWD 0 0 0 0

In FC8, instead, using cifs I can't obtain the same result: mounting 
always fails. The problem seems to be related to mount.cifs:

$ smb4k_mount -t cifs -n //server/dir  ./a -o  
username=MYUSERNAME,password=MYPWD

mount error 1 = Operation not permitted
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

How can I make this configuration work? I can neither change
the user exporting the share nor change my local user.

I'd like to use the good old smbfs, but it seems to have been
completely removed from Fedora kernels (why? ) .

Thanks,
	Nico
