Attempting to configure Certificate based authentication with SASL External
such that if TLS successfully completed the user is authenticated by
certificate DN as an authenticated user without the requirement for the
corresponding DN to be present in the Directory Server.
nsslapd-sasl-force-external: on is part of the puzzle what other SASL
mapping configurations are required to allow successful completion of
authenticated access. We can complete OU, O, C RDN values can be mapped and
certificate trust for clients properly configured, but cannot necessarily
make any mappings on certificate CN RDN values.
Example cert DN value: cn=[Lastname.Firstname.MI], OU=[Affiliation],
O=[Company Name], C=[ISO 3166 Country Code]
were OU could be multivalued in cert RDN.
