After looking at a series of posts on the Internet, I have found that it is the problem of GVFS without Samba support. Consequently, the solution on Fedora is very very simple, just install the gvfs-smb package.
# yum install gvfs-smb
Actually, the most time-consuming part is the problem caused by myself, perhaps. There is some conflict between samba4 and samba (3) on my Fedora 17. The _local repository contains libwbclient v4 which is conflict with gvfs-smb which uses libwbclient v3. It takes very long time to recognize the reason and to solve it. If you meet the same problem on new Fedoras (16, 17) and cannot solve it, please leave a comment here.
