> When using Hadoop Ldap Group mappings in an enterprise environment, searching groups
and returning all members can take a long time causing a timeout.  This causes not all groups
to be returned for a user.  Because the first search only searches for the user dn and the
second search retrieves the group member attribute, we only need to return the group member
attribute on the search speeding up the search.
