I have tested that Samba does work over a cfuse or kernel mount point. I only tested basic functionality via a dedicated user account (not AD). We'll soon be testing with AD and the acl_xattr VFS layer which stores Windows ACLs on each file in the filesystem under the 'user.NTACL' xattr as a blob. That's largely independent of the ceph VFS module we're preparing, which will keep this all in userspace.
