[Samba] mount: Only root can do that

[Prianggada I Tanaya]

Dear list,

I perform mount as user, but the above message always appear, and
mounting fail. 

#mount -t  smbfs -o username=[username] //somemachinename/userhome
 /home/userhome/mnt/SOMEMACHINENAME/homes

mount: Only root can do that.

As super user, I could do that, but this is not preferable.
Please let me know how can I simply mount as user.
TIA

I use Mandrake 9.0, samba 2.2.6.
