Puppet users - Aug 2014 - Puppet Template for controlling puppet nodes puppet.conf file help

I have created a module for my environment that would control the content 
and formatting of the puppet.conf file on my nodes however I have ran into 
a problem with this.  The problem is, I have a few servers out in my 
environment that was built with their hostnames in all caps. What happens 
is that when I first connected them to the puppet master and they created 
their certs everything is in lower case but when the puppet.conf 
controlling module is applied to the server, the certname in the 
puppet.conf file on the node gets changed to the All Caps name which brakes 
its communication to the puppet master. For application reasons I can't 
change the hostname from All Caps back to lower case so how can I modify my 
template so that it would populate the certname with the FQDN in lower case 
letters?
 
So for example:
 
The certname in the puppet.conf file is helpme.puppethelp.com but when my 
module is applied it changes the certname to HELPME.puppethelp.com  - I 
know that with the <%= fqdn %> variable, this is getting it from facter 
which is querying /etc/hosts
 
 
Below is my templale for the puppet.conf file.
[main]
    # The Puppet log directory.
    # The default value is '$vardir/log'.
    logdir = /var/log/puppet
    # Where Puppet PID files are kept.
    # The default value is '$vardir/run'.
    rundir = /var/run/puppet
    # Where SSL certificates are kept.
    # The default value is '$confdir/ssl'.
    ssldir = $vardir/ssl
[agent]
    # The file in which puppetd stores a list of the classes
    # associated with the retrieved configuratiion.  Can be loaded in
    # the separate ``puppet`` executable using the ``--loadclasses``
    # option.
    # The default value is '$confdir/classes.txt'.
    classfile = $vardir/classes.txt
    # Where puppetd caches the local configuration.  An
    # extension indicating the cache format is added automatically.
    # The default value is '$confdir/localconfig'.
    localconfig = $vardir/localconfig
    certname = <%= fqdn %>
    server =  <%= puppetserver %>
    pluginsync = true
    report = true
    graph = true
 
Thanks for your help.
