further troubleshooting on my part with ldapsearch/debugging turned up, gave me the following:TLS: certdb config: configDir='/etc/openldap/certs' tokenDescription='ldap(0)' certPrefix=" keyPrefix=" flags=readOnlyTLS: using moznss security dire /etc/openldap/certs prefixTLS: error: tlsm_PR_Recv returned 0 - error 21:Is a directoryTLS: error: connect - force handshake failure: errono 21 - moznss error -5938TLS: can't connect: TLS error -5938:Encountered end of fileldap_err2stringldap_sasl_bin(SIMPLE): Can't contact LDAP server (-1)searches I;ve done on this error seem to point to certificate/openSSL problems.Anyone run into this before?

After having some packet traces done, what was revealed is that from a windows client running the softerra ldap browser, we could see the connection be established between client and server (syn, ack synack) client requests sending of data, and server resets/closes the connection, never sending any data, as I also saw with attempting to telnet to port 636 - connection is closed by remote host.Regarding the question of is TLS enabled, if I understand the doc correctly, the answer is yes. With respect to the TLS_REQCERT never statement, I believe it was set this way because this was only intended to be a testing server.contents of ldap.conf:
