Here’s my test using openssl from command line to
test SSL connectivity to Microsoft Active Directory Server
over SSL.
Please note the highlighted texts. This test was
run on a Linux machine.
Note that if I specify -CAfile option, the
connection was successful.
But if I use -CApath option, the connection would
fail with error “Verify return
code: 21 (unable to verify the first certificate)”.
Any input/feedback would be much appreciated.
Thanks.
Daisy

extract your CA certificates from /path/to/ldap_certdb to pem file(s) and use those files
instead of using the cert/key db.
Do you know if
there are existing tools (perhaps already bundled with
OpenSSL) that I can run to extract the CA certs to .pem
files from /path/to/ldap_certdb?
certutil -d /path/to/ldap_certdb
-L # list the certs
certutil -d /path/to/ldap_certdb
-L -n "name of CA" -a > cacert.pem # extract named CA
cert to pem file
Thanks in
advance.

My simple test
program (for testing LDAP SSL connection to AD server) using
Mozilla LDAP C-SDK looks something like this (this test
program works, connecting to AD over SSL works fine):
Right. The reason it works fine is because
mozldap uses moznss for crypto - you are using a build of
openldap that uses openssl for crypto. You will need to
either rebuild openldap to use moznss for crypto, or extract
your CA certificates from /path/to/ldap_certdb to pem file(s) and use those files
instead of using the cert/key db.

I know there’s
no problem with LDAP certificate store /path/to/ldap_certdb
because a simple LDAP client test program written in Mozilla
LDAP C-SDK worked fine connecting to this same AD server,
over SSL.
I need to know
if I am using the correct OpenLDAP client API calls.
Yes, but it looks like you are using
OpenLDAP built with openssl, not Mozilla NSS. If your
OpenLDAP is provided by some vendor, and you cannot
change/rebuild with moznss support, you'll have to export the
CA certificate(s) from the /path/to/ldap_certdb and pass them
to OpenLDAP with either a single file and LDAP_OPT_X_TLS_CACERTFILE or an
openssl style ca cert dir with LDAP_OPT_X_TLS_CACERTDIR.
Any input would
be much appreciated.
Thanks.

Hi, OpenLDAP
developers,
Do you have any
sample test programs (or code snippets) that uses OpenLDAP
client API to connect to LDAP server over SSL?
Thanks in
advance.
