This comes from those objects being private. Debating best course of action.

r3794 & r3797 have an initial solution for this.

Both admin objects (experimenter, group, groupexperimentermap) as well as root owned enums will all suffer from now having the default permissions = rw----. IAdmin and IType should automatically apply --r-r- to the items it creates, but other code paths may cause problems. Let's test it and find out.

from devteam:

...[could] make group a global object (no owner) and add an owner field (like we did with sessions), but I'm unsure how extensive that change would be. How many people are joining "group.details.owner"? Because all of those queries would have to change.

Ola, have you seen this problem with Events & Logs?

[atarkowska]

I sow first time only on groups.

[jmoore]

Ok. Assuming closed. May have to re-open. (unlike Experimenter/Event/Logs?, etc., ExperimenterGroups and GEMs have owners, so this may be isolated)
