Re: Server Certificate Chain

["Krasimir Ganchev" <ganchevk@gmail.com>]

Kari,

 

I have already tried adding my Root/Child certificate bundle via TLSCACertificateFile but it doesn't make any difference and according to the documentation the directive only specifies certificates for CA's that slapd will trust.

 

The other thing which I have tried was adding the Child /subordinate/ CA certificate right after the Server certificate in TLFCertificateFile which also didn't lead to any success.

 

Of course I could always add the Child CA certificate to all of the Windows machine stores and evrything would work just fine, but that's not the whole idea of paying for trusted certificate.

 

I would like to be able to specify the server certificate chain just like I've done that with SSLCertificateChainFile in apache2 for example.

 

~Cheers~

I have file (on Linux) /etc/ssl/certs/trivore- ca-bundle.crt, which looks
like

# The Trivore 4096 rootCA certificate:
-----BEGIN CERTIFICATE-----
MIIGhjCCBG6gAwIBAgIBADANBgkqhkiG9w0BAQQFADBtMQswCQYDVQQGEwJGSTEW
...deleted...
aumDU+F7CFlUMZllhTLmiAYN14j7chcClbHfREhopXPTtVb5EyJ6EQK+
-----END CERTIFICATE-----
# ...
# The Trivore 4096 CA 01 certificate:
-----BEGIN CERTIFICATE-----
MIIGqDCCBJCgAwIBAgIBATANBgkqhkiG9w0BAQUFADBtMQswCQYDVQQGEwJGSTEW
...deleted...
Dyc4ZHUjqXz/n/CQjWBCwKPxF3fwci7UZuly9g==
-----END CERTIFICATE-----

..and then in the slapd.conf:

TLSCACertificateFile /etc/ssl/certs/trivore-ca-bundle.crt
TLSCertificateFile /etc/ssl/certs/hostname.crt
TLSCertificateKeyFile /etc/ssl/private/hostname.key
TLSCipherSuite HIGH

among other lines.

hostname.crt is created by CA01 during certification process.

Just having appropriate/relevant lines in ldap.conf makes the client
work nicely with the server.

Same goes, if you import the rootCA and subordinateCA (CA01) to your
Windows box.  There is a separate slot on Windows for root and
intermediate/subordinate CAs.  ...but that goes outside the scope of
this list.

Did it help?
