Then would the 'common name' for use in the certificate be:

Any assistance is greatly appreciated.

Try to connect to ldaps://localhost:636
Cn must be localhost if that's configured in the certs, but... Are you sure
that localhost should be the fqdn?

Hey Ken, is port 636 open on the host-based firewall if it's running?
any other firewalls blocking 636?
CP
8:40 a.m.
Thanks for the suggestions everyone,
I've corrected an issue with the generation of the self-signed CA , I was using the
wrong 'cert'
For OpenSSL this gets put into:
/etc/pki/CA/cacert.pem
I have used the "Common Name" in the cert-generation as: server.my-domain.com
I have it in /etc/hosts as:
127.0.0.1 server.my-domain.com
I am using 'localhost' first in this investigation-stage, and will be used for our
unit-tests
The port 636 does not appear to be firewalled
I get a little farther now with these changes, 8 bytes are sent/received: see below TLS:
can't connect: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert
handshake failure.

Hey Ken, is port 636 open on the host-based firewall if it's running? any other
firewalls blocking 636?
CP
2:10 p.m.
I've built and installed the openssl 1.1.1c thinking my issues are incompatibility
between the version of openldap and original openssl v1.0.2f installed on my Centos 7
I get one step farther now, from the client's debug output, but still fail at
"tls_post_process_client_hello:no shared cipher."
Does anyone know why there is no shared cipher, when both server and client run on the
same machine, and use the same libssl ??
Is there a config option I'm not aware of?

Subject: RE: Issues with OpenLdap using OpenTLS
Thanks for the suggestions everyone,
I've corrected an issue with the generation of the self-signed CA , I was using the
wrong 'cert'
For OpenSSL this gets put into:
/etc/pki/CA/cacert.pem
I have used the "Common Name" in the cert-generation as: server.my-domain.com
I have it in /etc/hosts as:
127.0.0.1 server.my-domain.com
I am using 'localhost' first in this investigation-stage, and will be used for our
unit-tests
The port 636 does not appear to be firewalled
I get a little farther now with these changes, 8 bytes are sent/received: see below TLS:
can't connect: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert
handshake failure.
