Not currently, maybe it will...  Depends on how many wants it.

Yes, but I think that's a poor excuse for doing it on the server side.
I think this should be done by the client in most cases.  One might
also need to take the clients locale into account when sorting the

It's not that hard.  What I do, is that I create a new simple array
with just the attribute values I want to sort on and preserve the
indices of the result array.  Next I sort that array (again
preserving indices).  The indices of the sorted array now give me
the order I should use when displaying the entries from the result
array.  Not that hard, it looks something like this:

$info = ldap_get_entries($ds, $sr);

for ($i=0; $i<$n; $i++) {
for ($j=0; list($i,) = each($cn);) {
      $sorted[$j] = $info[$i];

Anyway, the next PHP release (in CVS or snapshots now) will have a
function ldap_sort() for client side sorting.  After you've done
the search, simply do ldap_sort($ds, $sr, "cn");
and you have sorted the results on cn, and you access the result
as usual afterwards.
