I never delt with modnss before20 means SEC_ERROR_UNTRUSTED_ISSUERCan you provide the entire log leading up to this point? you can paste it to fpaste.org if you don't want to spam the list with too much information.Yes, openldap with moznss should work _exactly_ like openldap with openssl. If this is something that was working before this is a bug that needs to be fixed asap.I ran the same ldapsearch command from a Centos box which has openssl and the error messages says this :TLS certificate verification: Error, self signed certificate in certificate chainwhich is not true. I have separate CA certificate and server certificate. The server certificate is signed by the CA certificate.openssl seems to be complaining about the CA certificate: #TLS certificate verification: depth: 1, err: 19, subject: /C=CA/ST=Ontario/L=Toronto/O=Epic Media Group/OU=IT/CN=Epic Media Group root CA/emailAddress=sysadmin@theepicmediagroup.com, issuer: /C=CA/ST=Ontario/L=Toronto/O=Epic Media Group/OU=IT/CN=Epic Media Group root CA/emailAddress=sysadmin@theepicmediagroup.com#TLS certificate verification: Error, self signed certificate in certificate chainNote that the subject: is the same as the issuer: - that is, it is a self signed certificate (self issued).But I'm not sure if this is the real problem.That certificate it is complaining about is actually the ROOT CA. But I have another server certificate specified by "olcTLSCertificateFile: /etc/ssl/certs/ldaprov1.crt" in cn=config and its subject and issuer are shown below:certs]# openssl x509 -noout -issuer -subject -in /etc/ssl/certs/ldaprov1.crt issuer= /C=CA/ST=Ontario/L=Toronto/O=Epic Media Group/OU=IT/CN=Epic Media Group root CA/emailAddress=sysadmin@theepicmediagroup.com subject= /C=CA/ST=Ontario/L=Toronto/O=Epic Media Group/OU=IT/CN=ldaprov1.prod/emailAddress=sysadmin@theepicmediagroup.comIts that the client can't seem to get it for some reasons.# TLS trace: SSL3 alert write:fatal:unknown CA Do you have the CA cert on the client machine?I put the same CA cert on the client machine, both in /etc/ldap.conf(/etc/nss_ldap.conf on Fedora now) and /etc/openldap/ldap.confThat is what I have been doing, or trying to do the whole time.
