The reason for this blog post is that one of our customers called after noticing some unexpected behavior when
they were trying to use the Server 2008 certificateweb enrollment page to request a Version 3 Template based
certificate. The problem was that no matter what they did theVersion 3 Templates would not appearas
certificates which could be requested via the web page. On the other hand, version 1 and 2 templates did
appearin the page and requests could be done successfully using those templates.
