[Samba] write access for regular users

[Vano Beridze]

Hello

My configuration is

Fedora Core 1
uname -r
2.4.22-1.2188.nptl

rpm -q -a | grep samba
samba-client-3.0.4-1.FC1
samba-common-3.0.4-1.FC1

I can connect to windows shares with no prob and I can read
files with my linux regural user, but in order to write to windows share
I have to become root. I do have write permissions on windows share.

How do I configure my linux box in order to write to windows share with 
my regular user?

groups
wheel users

Thank you
