Pull a value out of policy or enforce a policy on one user.

My goal is to look at the policy applied to an object and pull a value the policy would set.

Specifically, I'd like to pull homePath and homeDirectory out of the Home Folder and AutoProvisioning Policy applied to a user object.

This looks close to what I'm trying to do. Not sure what ]$PolicyRule is supposed to be in this situation, is it the name of the policy?

# Return value
# String with generated value

function ExecutePolicyRule ([string]$PolicyRule , $Request)
{
$value = $PolicyRule
$rex = [regex]'(?:%<(?<name>.+?)>)'
$neededAttributes = $rex.Matches($PolicyRule) | %{ $_.Groups['name'].Value }
$neededAttributes | %{ $value = $value -replace ('%<' + $_ + '>'),(GetActualAttribute $_ $Request) }
return $value
} #-- ExecuteGenerationRule

I would also be OK with an enforce policy option.
