[users@httpd] using ldap secure causes core dump

If I attempt to use ldaps I get

[Mon Nov 24 10:19:07 2008] [debug] mod_authnz_ldap.c(582): [client 
150.125.168.140] ldap authorize: Creating LDAP req structure
[Mon Nov 24 10:19:15 2008] [notice] child pid 26129 exit signal 
Segmentation fault (11), possible coredump in /usr/local/httpd

Works fine in non-secure mode

Any ideas on what I can do get some more info on whats going on ?

That final invocation of libtool doesnt reference /usr/lib, which is
almost certainly where libnet lives. Have you done some hackery to
remove /usr/lib, to avoid it finding LDAP libraries in there?

Could you email, or put on a pastebin somewhere, the contents of:
<apachedir>/config.nice
<apachedir>/config.log
<apachedir>/srclib/apr-util/config.nice
<apachedir>/srclib/apr-util/config.log

Cheers

They probably have the SSL libraries staticly linked in.

Yeah, that is unlikely to work. How about manually installing apr and
apr-util (you'll find them in httpd-2.2.10/srclib/apr and
httpd-2.2.10/srclib/apr-util). When you come to build apr-util, you can
pass the LDAP library path to the configure script with something like
'--with-ldap-include=/usr/local --with-ldap-lib=/usr/local
--with-ldap=/usr/local/lib/libldap.so'. 
Thats probably not exactly right, but play around with it and then it
should be fine. 
Once you have apr/apr-util built correctly, configure httpd to use those
installed versions with '--with-apr=/usr/local/bin/apr-1-config
--with-apr-util=/usr/local/bin/apu-1-config'.

BTW, your emails all seem to come through as HTML email attachments.

Output of these commands please:

ldd /path/to/sbin/httpd
ldd /path/to/mod_ssl.so
ldd /path/to/mod_*ldap*.so

You almost certainly have httpd/mod_ssl linked to one OpenSSL library,
and mod_{,authnz_}ldap linked to another. Those commands should
demonstrate that. The solution is to rebuild/reinstall apache.
