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?

I am able to connect to my home-built OpenSSL installation (from Dec-19 sources) on CentOS-7 without the TLS bind.
I am now trying to use OpenTLS with OpenSSL, which is not currently working. From searching the internet I find this,
Which indicates that maybe RH-based-unixes have unique issues with OpenTLS/OpenLdap:
https://serverfault.com/questions/437546/centos-openldap-cert-trust-issues
My slapd.conf now holds (as differs from the default installed slapd.conf)
… snip…############### TLS
# added per http://www.openldap.org/faq/data/cache/185.html
TLSCACertificateFile /etc/pki/tls/certs/ca-bundle.crt
TLSCertificateFile /usr/local/etc/openldap/servercrt.pem
TLSCertificateKeyFile /usr/local/etc/openldap/serverkey.pem
TLSCipherSuite DES-CBC3-SHA
… snip…And my ldap.conf holds:
… snip…############### TLS

### fails:

… snip……. Having added the ‘cacert.pem’ into the file “ /etc/pki/tls/certs/ca-bundle.crt”
I get farther in the authentication than using “/usr/local/etc/openldap/ cacert.pem”:

Additionally:
I am reading the FAQ http://www.openldap.org/faq/data/cache/185.html to generate the certs
but am wondering if I am correctly understanding the instruction “Remember that the Common Name for this cert should be the fully qualified domain name of the server:”
If I run my ldap server as:
/usr/local/libexec/slapd -F /usr/local/etc/openldap/slapd.d -h'ldaps://127.0.0.1:636 ldap://127.0.0.1:389' -d -1
Then would the ‘common name’ for use in the certificate be:
cn=localhost:636Any assistance is greatly appreciated.
Thanks!
