I can confirm this too with password protected samba shares.
Nautlius does not ask for credentials.
gvfs-mount does, but the created share does not work.
funny thing is when using the IP number instead of the host name, everything works as expected (nautilus and gvfs-mount). In this case credentials are asked and used.
e.g. smb://media/music works not, smb://192.168.0.4/music works.

hope this helps.
