README.TXT

The source code in this directory can be used to build a sample Policy Module 
for the Microsoft Certificate Server.  It is meant to run on Windows NT 4.0 
with SP3 or later or on Windows NT 5.0 only.  The Certificate Server must 
already be installed. 
 
The Certificate Server calls the Policy Module through the ICertPolicy 
interface, and the Policy Module can call back to the Certificate Server 
through the ICertServerPolicy interface. 
 
Each time the Certificate Server receives a certificate request, it passes 
control to the CCertPolicy::VerifyRequest method in policy.cpp.  The passed 
Context parameter is used with the ICertServerPolicy interface to retrieve 
properties from the request and potential certificate.  The VerifyRequest 
method may add, modify or enable Certificate Extensions, modify the NotBefore 
and NotAfter dates and Subject name RDN (Relative Distinguished Name) strings 
for the potential certificate.  It must also perform any validation required, 
and decide the disposition of the request.  The method should return one of 
VR_PENDING, VR_INSTANT_OK or VR_INSTANT_BAD to cause the request to be made 
pending, to grant the request and issue the certificate, or to fail the 
request. 
 
Once the policyvb.dll DLL is built, its COM interface must be registered 
via the following command: 
    regsvr32 policyvb.dll 
the Certificate Server service must then be stopped and restarted as a console 
application to load the newly registered Policy Module.  Use the Control 
Panel's Services applet, and stop the "Certificate Authority" service, then 
start the Certificate Server as a console application via the following 
command: 
    certsrv -z 
 
NOTE: Because this VB Policy Module uses an Interactive Form to display 
information passed in the certificate request, IT MUST BE STARTED VIA THE 
ABOVE COMMAND AS A CONSOLE APPLICATION in order to interact with the desktop 
to display the form and accept the user's input.
