 You can't assign configuration of this molecule unless you know the bonds that are coming towards you and going away from you. However, if you assume the least priority group points away from you this molecule has following configurations

1S, 2S 3R, 4S, 5S, 6S

 O-chem sucks when it mixes up stereochemistry and synthesis together alongwith all functional groups.
