Good morning Mr. Brown, Here is the results of your first query; executing the certutil command as you presented it (with adding my instance): certutil -L -d /etc/dirsrv/slapd-E2WAN/ Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI wsf-LabCA.lab.aero.org CT,, wsf-LabLDAP.crt u,u,u ///////// Here is the answer to your question about a CA referenced in my /etc/openldap/ldap.conf; I executed: root@wsf-LabLDAP:~> cat /etc/openldap/ldap.conf # # LDAP Defaults # # See ldap.conf(5) for details # This file should be world readable but not world writable. #BASE dc=example,dc=com #URI ldap://ldap.example.com ldap://ldap-master.example.com:666 #SIZELIMIT 12 #TIMELIMIT 15 #DEREF never TLS_CACERTDIR /etc/openldap/cacerts URI ldaps://wsf-LabLDAP.lab.aero.org/ BASE dc=lab,dc=aero,dc=org MY QUESTION is why do I need to reference anything with OpenLDAP, if I am using 389-ds, is it simply a place to put things without creating a separate directory structure? I do not know if my CA certificate is in the correct place; perhaps it is not because I knew I wasn't using OpenLDAP, I am using 389-ds, and I didn't understand the implementation steps properly and so I 'did it my way.' I store my certs up under /etc/pki/CA/certs; as shown below: root@wsf-LabLDAP:/etc/pki/CA/certs> ls wsf-LabCA.crt wsf-LabLDAP-AdminServer.crt wsf-LabLDAP.crt I am running CentOS-6.6; can I still get support here in this website? Mr. Brown, I can produce the output of an ldapsearch command and something that I believe confirms your suspicion; but I don't know what to do to fix the problem (in my VMs or on my REAL server). Here is the ldapsearch I executed and the results: root@wsf-LabLDAP:/> ldapsearch -d 5 -x -L -b 'dc=lab,dc=aero,dc=org' ldap_create ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP wsf-LabLDAP.lab.aero.org:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 192.168.2.243:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 attempting to connect: connect success TLS: certdb config: configDir='/etc/openldap/cacerts' tokenDescription='ldap(0)' certPrefix='' keyPrefix='' flags=readOnly TLS: cannot open certdb '/etc/openldap/cacerts', error -8018:Unknown PKCS #11 error.

I noticed you are a Red Hat Software Engineer; I hope that means you will still be able to support me on CentOS (but I guess RedHat owns CentOS now).
