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?

Ken From: openldap-technical <openldap-technical-bounces@openldap.org>
On Behalf Of [ext] Dunne, Kenneth 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

Hey Ken, is port 636 open on the host-based firewall if it's running? any other firewalls blocking 636? CP |
