With python-glanceclient 3.5.0:

$ glance member-update d362e24d-3d77-42ea-96ae-d1a1721e7d41 ebbcdabd911340efa9a3430488c43304 active
usage: glance member-update <IMAGE_ID> <MEMBER_ID> <MEMBER_STATUS>
glance member-update: error: argument <MEMBER_STATUS>: invalid choice: 'active' (choose from 'accepted', 'rejected', 'pending')

This was fixed at some point.
