好久没有配置samba了，由于同事要从windows下访问，但是总是有问题，google了一下，发现是SELinux的问题。
http://www.linuxquestions.org/questions/linux-general-1/unable-to-access-files-from-xp-via-samba-after-upgrade-to-fc6-514683/
http://lists.samba.org/archive/samba/2006-May/120632.html
It also suggested that this theory can be checked by switching off SELinux for Samba by:
/usr/sbin/setsebool -P smbd_disable_trans 1
But this will obviously lose the benefits of SELinux
