Went back to the docs again and this resolved that issue:
certutil -A -i /var/tmp/wrlc.org.crt -t "u,u,u" -d /etc/dirsrv/slapd-ldap -n "server-cert"
However, I now get this error:
[19/Oct/2011:10:34:36 -0400] - SSL alert: CERT_VerifyCertificateNow: verify certificate failed for cert server-cert of family cn=RSA,cn=encryption,cn=config (Netscape Portable Runtime error -8179 - Peer's Certificate issuer is not recognized.)
I am guessing that there are other certutil commands?
