Since this is now the top hit for “openldap Mozilla nss intermediate certificate,” here’s what I ended up doing:

It's not just openldap, it's many other components.

And, if you are a Red Hat customer, please report any problems with using Red Hat products with your support channel.  Red Hat is committed to making openldap + mozilla NSS work.


There, that aside, I noticed in the excellent FAQ  at http://www.openldap.org/faq/data/cache/1514.html that “If you previously used OpenLDAP with OpenSSL, and have certificate files, cipher suites, and other TLS settings specified in your configuration files, those settings should work exactly the same way with Mozilla NSS - OpenLDAP with Mozilla NSS knows how to read those settings, files, etc. and apply them in the same way.”  So, I went to ole-reliable /etc/tls/certs and generated a key and csr, put the key in /etc/tls/private, and put the signed cert in /etc/tls/certs.  I also put the geotrust intermediate cert in /etc/tls/certs as well, and then changed cn=config to read:


olcTLSCACertificateFile: /etc/pki/tls/certs/geotrust-intermediate.crt

olcTLSCACertificatePath: /etc/pki/tls/certs

olcTLSCertificateFile: /etc/pki/tls/certs/ds.clarku.edu.crt

olcTLSCertificateKeyFile: /etc/pki/tls/private/ds.clarku.edu.key


Happy TLS’ing everyone.

That was the intention - that customers upgrading from openldap + openssl to openldap + moznss should not notice or care about the underlying crypto implementation - it should just work exactly as before.

Subject: Mozilla NSS -- how to deploy intermediate certificate




I need to publish the GeoTrust intermediate certificate; I’m using 2.4.29 built against Mozilla NSS.  In OpenSSL world, I’d use -- I think -- TLSCACertificateFile /path/to/CA-certificates.  Here’s what I’ve tried:


Download GeoTrust cert from https://knowledge.geotrust.com/support/knowledge-base/index?page=content&id=AR1422 ; save as intermediate.crt


Import with:


# certutil -d /etc/openldap/nssdb/ -A -t ",," -n geotrust-intermediate -i  intermediate.crt


Certutil -L now shows:


# certutil -d /etc/openldap/nssdb/ -L


Certificate Nickname                                         Trust Attributes



geotrust-intermediate                                        ,,  

ds.clarku.edu                                                Pu,Pu,Pu



cn=config looks like this:


olcTLSCACertificateFile: geotrust-intermediate

olcTLSCACertificatePath: /etc/openldap/nssdb

olcTLSCertificateFile: ds.clarku.edu


But still clients cannot verify the cert.


Any Mozilla NSS guru’s know what I’m going wrong?
