Probably worth mentioning the lines from slapd.conf:
TLSCipherSuite HIGH:MEDIUM:+SSLv2
TLSCACertificateFile /usr/local/etc/openldap/cacert.pem
TLSCertificateFile /usr/local/etc/openldap/servercrt.pem
TLSCertificateKeyFile /usr/local/etc/openldap/serverkey.pem
All files exist, and appear to be correct.
