Release Notes: Bug Fix
Release Notes Summary: This change fixes an issue with the directoryservice user provider in OSX, where puppet would crash in certain circumstances while fetching bad ShadowHashData from the system. Puppet now handles this gracefully.

 Description   

Possibly related to link PUP-6410, if the user/directoryservice provider's get_attribute_from_dscl method returns nil when trying to fetch ShadowHashData, the whole thing explodes.

We've only seen this rarely, and only when the provider's trying to read an empty username (which is probably another bug that should be handled).
