Hi!
Here it works with these settings:
olcTLSCACertificatePath: /etc/ssl/certs
olcTLSCertificateFile: /etc/ssl/servercerts/slapd.pem
olcTLSCertificateKeyFile: /etc/ssl/private/slapd.key
Could it be a permissions problem? Did you try to check the certificate chain with
openssl (preferrable as LDAP user)?
When I run the openssl s_client command I get no errors, but I also get
no intermediate or root certificates sent. I see this in the output: "No
client certificate CA names sent".
It appears that OpenLDAP is not sending the intermediate or root
certificates.
However, if I put all the intermediate and root certificates into a
single file and point olcTLSCACertificateFile at this file, those
intermediate certificates _are_ sent.
So, it appears that olcTLSCACertificateFile sends the certificates but
but olcTLSCACertificatePath does not.
Am I misunderstanding the purpose olcTLSCACertificatePath?
Thanks.
