The certificates my Microsoft CA is generating do not match the time period indicated in the template used. How can I resolve this?

I recently created a new certificate template for use on my Linux boxes on my Microsoft CA (2008 R2 Enterprise). This template is approved for server and client authentication purposes with a validity period of 10 years - the expected lifetime of our Linux boxes - and the subject name supplied in the request. I have checked both the intermediate and offline CA - both have more than 10 years of life listed.

Is there some kind of hard limit I'm hitting here?

We have observed some puzzling behavior from the CAs we have set up in both the past and present.
