2. Log in as an admin user that was not invited to join the group and comment the file.
there is an error commenting the file
When a group is created and set as private or secret, it's recommended to the External Storage Providers to limit access to it. But if they do, all admins in Jive can still modify the group content while never being sent as members to the ESP. ESP will therefore forbid them from accessing the group for changing, while Jive will display all the controls.
The initial request for creating a group/place has a membership operations field that should add all admins for private groups if ESP is supposed to know it should let them access.
