[ubuntu] samba sharing write permissions

view story

http://ubuntuforums.org – Hello! I have a computer running ubuntu 10.04,and want share some folders on it.The operating system is on one hdd and i have other 2 hdd in RAID1.Everything looks and acts ok until I try to share a folder. I can see all sharings, but I get access denied everytime I try to write logged in as user and not as root no matter the location of the folder (Raid or users home). I forgot to mention that I want an xp user to write in a specific folder on the ubuntu computer.The only situation I can write is when I share [homes] using samba, and the folder is located on /home/user/desktop/sharedfolde (Hardware)
