[Puppet Users] shared header across multiple defined types via concat

Hello All,

I have two defined types which I'd like to share a common, realized
header concat resource but when both are declared in a manifest the
header is only applied to one of the types. When the headers are
declared independently for each type the work but that's is a bunch of
nearly identical code that should be able to be reused, but i'm
missing whatever magic is needed to accomplish it.

The class is pam and the defined types are pam::access and
pam::limits. I've only included init.pp and limits.pp since access.pp
is nearly identical but the full module can be found at
https://github.com/deadpoint/puppet-module-pam.

Any thoughts on how to accomplish this?

init.pp:
class pam {
include concat::setup
$access_conf = '/etc/security/access.conf'
$limits_conf = '/etc/security/limits.conf'

@concat { $limits_conf:
owner => 'root',
group => 'root',
mode => '0644',
}
# header
@concat::fragment { "header":
target => undef,
name => undef,
order => 01,
content => template("pam/header.erb"),
}
}

limits.pp:
define pam::limits ( $domain, $type, $item, $value, $ensure =
present, $priority = '10' )
{
include pam
$limits_conf = $pam::limits_conf
realize ( Concat[$limits_conf] )
Concat::Fragment <| title == 'header' |> { target => $limits_conf,
name => "limits" }
concat::fragment { "pam::limits ${domain}-${type}-${item}-${value}":
ensure => $ensure,
target => $limits_conf,
content => "${domain} ${type} ${item} ${value}\n",
order => $priority,
}
}
