I believe JNDI strips spaces internally from the beginning and end of a
filter, but it doesn't strip other forms of whitespace. So the following
template would works as well:

     <FilterTemplate>
         <![CDATA[
             #if (${attribute.isEmpty()} || ! ${attribute.get(0)})
               <dummy filter guaranteed to return no results>#else
               <"real" LDAP search filter>#end
         ]]>
     </FilterTemplate>
