This guidance is an extraction from the document “Installation Guide – Microsoft Windows 2008 Server – CA, AD and CRL” – chapter 7.1. Here we define the certificate templates used in production of smart cards in the Buypass LRA. If the CA, AD and CRL already are installed and the only extra you need is to modify the templates in order to get started with Buypass LRA this document will be enough. This document defines how to add new templates before production startup.
Buypass Certificate Templates in Microsoft CANot all the templates should be based on the 2008 templates. This is because Buypass p.t. do not have support for the 2008 templates new crypto algorithms in our CSP used for smart card logon.
Also make sure that minimum "key size" is1024, but 2048 for client templates. Buypass smart cards do not support "key size" greater than 1024 p.t.
There are defined a number of templates for certificates and Enrollment Agents. | Certificate Template Name | Description |
|---|
Buypass SmartCard Logon | Certificate issued to the smartcard for logon | Buypass SmartCard Enrollment Agent | Certificate issued to LRA ADM and LRA Operators so they will be able to issue logon certificates to regular users | Buypass Temporary SmartCard Logon | Certificate issued to the smartcard for temporary logon |
Certificates with validity more than 2 years Microsoft has set a default validity period for all certificates to a maximum of 2 years. This must be adjusted to maximum 3 years since the user certificates will last that long. You modify the profiles by running the commands: certutil-setreg ca\ValidityPeriodUnits 3
net stop certsvc
net start certsvc The command will tell you the old value and then change to the new value.
