No idea about the cephs part, but your smb.conf isn't correct, your 
workgroup shouldn't be the same as the realm, perhaps use 'INT' instead. 
You have no 'idmap config' lines, how are you going to map your AD users 
to Unix users ? You have 'guest ok = yes' set in [plm] but you do not 
have 'map to guest = bad user' set in [global], so guest access will not 
work. Finally, by setting 'vfs objects = ceph' in [plm], you have turned 
off acl_xattr on the share.
