I was just following the instructions on the web site, I misunderstood
what was meant by CVS HEAD. Will attempt to download release 2.4.23 in
my next attempt.

I think I misunderstand exactly what is meant by "enable the deref and
rdnval overlays".  I assume this is something that is built from
OpenLDAP source, and running configure script with
--enable-overlays=mod --enable-modules handles that.
After make // make install rndval.so.0.0.0 lives in
/usr/local/libexec/openldap along with symlinks for rdnval.so and
rdnval.so.0, the rdnval.a and rdnval.la also exist. As for deref, I
get deref.la, deref-2-devel.so.0.0.0 along with symlinks for deref.so
and deref-2-devel.so.0.

It's clear that the provision script is not making it past the
connection to slapd, BUT I think a key element here is the fact that
no configuration files are being created for slapd to start with. You
reference adding some ldap logging to my .ldif file, but my
/usr/local/samba/priate/ldap/slapd.d/ directory is completely empty.
So if my guess is correct, the provision script generates some ldap
files to kick off slapd with, and that's the step that it's not
getting past. A couple of confusing pieces to the puzzle for me are :
1) first time provision script is run, it complains about rdnval //
missing file, second time it runs, it stops complaining about rdnval
and just complains about missing .ldifs
2) I have an OS that I got this working on friday night, but am now
unable to reproduce the results
-The only difference I can tell between what I got working friday
night and what I can't get working now are installed OS packages, and
differences in CVS from then until now. I would assume that it's the
former BUT i've compared all installed packages between the two
systems and aside from maybe a dozen small version differences in
packages that shouldnt have anything to do with openldap / samba, I
cant find any differences.
I'll continue to try to compare between systems, and try to install
2.4.23 on a new system to see if I can get that working. Will post on
progress.
