I am trying to use the Admin SDK Directory api to look up user profiles. I am able to do this successfully all day (with in quota) with 99% of the time. Though there are certain times where it just fails no matter what.
Yes I have set the service account user, I have the proper scopes, I have admin api turned on.
It even fails in the google api explorer. See screen shots

Sorry for the links, images keep showing as broken
After contacting google they supplied an answer. There is a setting for the contacts app that enables and disables this.
Admin console >> Google Apps >> Settings for Contacts >> Advanced settings
Contact sharing: Enable contact sharing
Make sure that is enabled and it works.
