Hi Bayard,
in my previous request I was very brief and unspecific. I try
to provide you more informations.
The goal of my project is adding two new databases in the nss.
First database will be called x509pkc and it will store X509 PKCs.
In the files backend its syntax will be
username X509_PKC_PEM_FORMAT
Second database will be called x509ac and it will store X509 ACs.
In the files backend its syntax will be
username X509_AC_PEM_FORMAT
The principal backend to two databases is not files, but ldap.
The frontend for this two database will be provided by functions:
getx509pkcnam(const char *name)
getx509acnam(const char *name)
At the moment OpenLDAP supports x509 PKC and AC syntaxes,
PKC syntax is a work of Kurt Zeilinga, AC syntax is my work
delevoped for the thesis of first level university deegree.
I submitted this work at OpenLDAP comunity and it was included
in OpenLDAP suite.
Can you suggest me some documents and relevant materials to study,
helpful for this project ?
Thank you.

Luca,
As this is a student assignment, the proper spirit seems to require
answering mostly with pointers to further relevant materials or to
further considerations that appear minimally necessary to arrive at
adequate answers.
For item 1, I expect the comments in /usr/include/nss_common.h
should be adequate to evaluate your understanding.
For item 2, I don't see why you'd expect to modify a system header
in adding a new name service to an architecture that's supposed to
be extensible by third parties. The header in question is supposed
to be code for nss provider implementations from Sun, so you
probably don't want to give it anything other than exemplary value.
A few other points:
it's not correct to refer to getXXXbyYYY as a system call
I don't really follow your understanding of the source organisation
(why separate source for each of the pw lookup functions?)
you're not proposing to create multiple backends, just a single new
backend for a new database to query pw data (again, reading
nss_common.h indicates that the term backend is either a synonym for
database or specifies the instantiation of a backend source pair)
you've talked about source organisation but not specified the file
object(s) or installation requirements
Cheers,
Bayard
