Assign Vault privileges based on organizational unit
The Manage Exports and Manage Searches Privileges in Google Vault can now be granted to a user for an entire organization, or only for specific organizational units (OUs). For example, you can assign a Vault administrator the Manage Searches privilege for your whole organization and the Manage Exports privilege for one OU. Privileges are still assigned in the Admin console by your Google Apps administrator.
