Windows CA template – web server and private key export

Creating a web server certificate request is very easy when using a Windows CA server. There is one disadvantage. The requested certificate is directly stored in the user store (by default) or the local computer store, if specified during the request. The disadvantage is that you cannot export the requested certificate including the private keys. During the request the option to Mark keys as exportable is grayed out.

There is a way to mark the keys as exportable when using a Windows CA server. You need to create a new Web Server Certificate template. You can use the existing Web Server Certificate Template as default and copy the current settings. To do so, you just:

  • run certtmpl.msc, which will open the Certificate Template snap-in;
  • click the Web Server certificate template;
  • choose Action – Duplicate Template;
  • configure a unique template name;
  • choose the tab Request Handling;
  • enable the option Allow private key to be exported;

That is all you need to do. You can now request a new certificate with the newly create certificate template. After the certificate is issued and installed on the user or local computer store, you can export the certificate including the private key.

Cacti and HP Procurve

Finding a template for HP Procurve switches wasn’t that hard. I needed to find a template for HP Procurve 2510G switches. The place to look for templates is forums.cacti.net. I searched the forums on the key word “procurve”, which resulted in many hits. I used the template from the article HP procurve 2600 series.

After importing all template you have the ability to monitor the MAC count on the switch and the memory usage. You also have the option to monitor the CPU usage, but you have to do some extra configuration. The zip file only contains a data template for the HP switches, but no graph template. I created my own graph template by duplicating the Cisco CPU graph template and changed the data source to the HP data template.

Graph Template Data Source

I changed the data source for the first 4 Items in the Graph Template to the HP procurve CPU data source. Next I created a device for the HP switches and added the appropriate “Associated Graph Templates” for HP procurve CPU, MAC count and memory usage. Now you only need to create a graph for the template and you are set to go.
