For what I know SMBFS is the old way of doing things ("smbfs has not been maintained in the last few years" (http://www.samba.org/samba/smbfs/)) so I would suggest using CIFS.
Now what the filesystem is on the server that is sharing it does not rely matter as long as you have permission to access it (see Username and Password in my example). The network protocol will do the rest.
