(ITS#6684) Patch for autogroup overlay

[norbert@pueschel.net]

Full_Name: Norbert Pueschel
Version: HEAD
OS: Solaris
URL: http://www.pueschel.net/openldap/norbert-pueschel-autogroup-25102010.tar
Submission from: (NULL) (80.152.154.98)


When starting to use the autogroup-overlay from the contrib directory, I
stumbled over some issues:

1) Using non-DN-valued URIs for autogroup does not work correctly, even
with the latest version from HEAD. Especially changing group member is
not tracked.

2) Using the memberOf-overlay for constructing autogroups does not work

3) autogroup crashes slaptools (e.g. slaptest) when used together with
the ppolicy-overlay.

4) The Makefile install the overlay into the wrong directory (lib,
should be libexec)

I have invested some time and found fixes for all these problems; see
the URL for the patch I uploaded.
