Export/Import certificate templates using ldifde:

ldifde -m -v -d “CN=WebServerTemplate,CN=Certificate Templates,CN=Public Key Services,CN=Services,CN=Configuration,DC=mydomain,DC=net” -f MyTemplateWebServer.ldf

Edit the MyTemplateWebServer.ldf to change the reference to the previous domain and replace by the new domain if you want to import

the template on another domain.

For import you should use the similar command:

ldifde -i -k -f MyTemplateWeServer.ldf

And this should work from the begining, starting from Windows 2000 Version.
