[Fedora-directory-users] Certificate to LDAP Mapping API

Hi all, I need to use “Certificate to LDAP Mapping” functionality. The README file in the source ldapserver/lib/ldaputil/examples path suggests: Refer "Certificate to LDAP Mapping API" documentation to find out about the various API functions and how you can write your plug-in. And also to refer “Managing servers” manual. But I couldn’t get those documents. How can I write my own plug-in for LDAP Mapping? Or what can I do with Certmap.conf file to configure Certificate to LDAP Mapping. Can somebody provide link to that document or explain what is Certificate to LDAP Mapping. Thanks in advance, Neuron Ring.
