/**
 * Performs recursive group membership lookup.
 *
 * This was how we did the lookup traditionally until we discovered 1.2.840.113556.1.4.1941.
 * But various people reported that it slows down the execution tremendously to the point that it is unusable,
 * while others seem to report that it runs faster than recursive search (http://social.technet.microsoft.com/Forums/fr-FR/f238d2b0-a1d7-48e8-8a60-542e7ccfa2e8/recursive-retrieval-of-all-ad-group-memberships-of-a-user?forum=ITCG)
 *
 * This implementation is kept for Windows 2003 that doesn't support 1.2.840.113556.1.4.1941, but it can be also
 * enabled for those who are seeing the performance problem.
