Use case example for certmap.conf for end user:
Customer has desire to share Enterprise Directory information across WAN
for contact information sharing, but has requirement for strong
authentication using PKI. PKI trust is a PKI Mesh utilizing cross
certification. Users information in Directory Server One (DS1) are
associated with users issued certificates from PKI One (PKI1). Users
information in Directory Server Two (DS2) are associated with users
issued certificates from PKI Two (PKI2).
DS1 has no awareness or cross population of entries with DS2, but PKI1
is cross certified with PKI2 and trusted by both populations. Users
associated with PKI1 have a business requirement to strongly
authenticate with DS2 to locate and collaborate with population of users
in DS2, but have no entry in DS2 and vice versa. By removing current
capability to strongly authenticate based on TLS configuration but have
NO DN in DS you are removing capability to use SASL External in a cross
certified PKI environment. User of the product will be forced to use
SASL GSSAPI that causes other security issues or requirements to setup
all of these Kerberos trust and ticketing handling that should not be
required, difficult to sustain and place external dependencies on usage
of the DS product in a federated environment as described.
If directory is utilized as something OTHER than repository for people
similar challenges will present themselves when certificates are issued
for devices, roles, and groups. Examples include but are not limited to
VOIP device address book capabilities such as CISCO VOIP phones or call
managers, Potentially for extending security capability in hosts that
have host based certificates that may require use of the directory for
backend business processes were Certificate trust and regular expression
checks of DN utilized for the TLS session may be sufficient to utilize
for ACI binding rules.

We would instead use the SASL mapping functionality to map the
in the cert to a DN that the DS knows about. The SASL mapping code
much more powerful and flexible than the certmap.conf code.

I'm not sure I understand - do you want the ability to do cert auth
without having to have a real entry in the directory server that
corresponds to the subjectDN?
