Have I missed something obvious or has OpenLDAP really forced me into the position of needing to add the intermediate certificate from my SSL CA Vendor into my trusted store on all my clients?It's a CA cert; have you tried adding it to the file specified by the TLSCACertificateFile option?Well, I never looked at it that way. Yes, adding the intermediate certificate to the file pointed to by the TLSCACertificateFile option on the OpenLDAP server appears to have worked.Amaazing what trouble you could save yourself if you actually read the documentation.He told he looked at the documentation. Documentation is not a novel, things must be organized to be easily found.
If you are having trouble configuring TLS certificates on your server, and don't think to read the TLS Server Configuration section of the Guide, I doubt the problem is in the organization of the documentation.
http://www.openldap.org/doc/admin24/tls.html#Server%20Configuration Section 16.2.1.1
Actual OpenLDAP configuration would be to place B (and maybe B1) certificate in TLSCACertificateFile/Path element, to be able to verify the Client certificate. The Server must also place A1 in this element, so it can be sent to the Client to help it verify the Server certificate.
So, during the TLS negotiation, B, A1, maybe B1, maybe A are sent to the Client for it to verify the Server certificate? (remember, this certificate is signed by A1, and A must already be known by the Client). That's a waste of bandwidth.
The TLS library doesn't do anything so stupid, it only sends the certificates that are part of the chain from the subject's cert up to the root CA.
