Possible implementation: create two groups filled with FS-SC members, one group for ro, the other for rw, for all beamtimes, for commissioning folders.
Current status: beamtime leader, beamtime applicant, BL manager and BL scientist may use the gamma portal to add users (who have DESY accounts) to a beamtime.
