 o fixes DIREVE-283
 o made search handler use a special getLdapContext method when the search
   operation is on the root DSE with (objectClass=*), scope = base, and 
   base = ""
 o allowed bind operation as anonymous even when anonymous binds are disabled
   in the configuration ... delayed checks for anonymous user operations until
   other operations are performed.
 o added test case to make sure anonymous access is still disabled for binds
   to anything other than root dse
