Open LDAP with SSL on Debian

First of all create a self-signed certificate by following the instructions at http://www.eclectica.ca/howto/ssl-cert-howto.php. I copied the private key and the certificates to /etc/ldap. Please make sure that the

private key is only readable by root.

Next add the following lines to /etc/ldap/slapd.conf:

TLSCaCertificateFile /etc/ldap/cacert.pem

TLSCertificateFile /etc/ldap/cert.pem

TLSCertificateKeyFile /etc/ldap/cert.key

Finally make sure that the LDAP server is listening at the ldaps port (636) by editing /etc/default/slapd

and restarting the LDAP server.
