Google Admin SDK Directory API acts weird since today (2014/02/13)
Question
Turns out that today methods get and list return different givenName, familyName and fullName of a given user if that particular user has a G+ profile with a different name.
EDIT: To be clear: get method returns the usual names but list method returns G+ names.
Has anybody else seen this behaviour?
You can try it using the APIs Explorer (https://developers.google.com/admin-sdk/directory/v1/reference/users)
