> We don't appear to be setting a timeout via
> http://docs.oracle.com/javase/6/docs/api/javax/naming/directory/SearchControls.html#setTimeLimit(int)
> before we search with
> http://docs.oracle.com/javase/6/docs/api/javax/naming/directory/DirContext.html#search(javax.naming.Name,%20java.lang.String,%20javax.naming.directory.SearchControls).
> This may occasionally lead to some unwanted NN pauses due to lock-holding on
> the operations that do group lookups. A timeout is better to define than rely
> on "0" (infinite wait).
