onPostModify Function

I strongly recommend to look at ARS SDK (contains sample code) look at other legacy forums.
here is example:
--------------
function onPreModify($Request)
{
if ($request.Class -ne "user") {return}

if (IsAttributeModified "desriptiopn" $Request) {
#If AD\user.description is modified do action here
}
}
# IsAttributeModified
function IsAttributeModified([string]$attr,$Request)
{
[bool]$Modified = $False
if($Request -ne $null)
{
$Item = $Request.GetPropertyItem($attr,0)
if($Item -ne $null)
{
if($Item.ControlCode -ne 0) { $Modified = $true }
}
}
return $Modified
}

Couple of options:

You can trap that specific attribute change with an ActiveRoles workflow start condition and then trigger your script that way.

OR

Your script can look at the $Request - it will tell you which attribute was changed. There is a library script available (free) from Quest that can help you to interrogate the $Request object for the modified attributes.

Thank you both of you. Yes I have looked thru the SDK. I'll do some modifications to my code to see what I can accomplish.

I'll have a look the workflows, we don't use those but I might be able to use them for this type of stuff.

The workflow start conditions in particular can save you a lot of coding when it comes to trapping events.

The nice thing about them too is that unlike script policies, you are not tied to a provisioning policy - this offers additional flexibility because you can have your scripts triggered in many different ways.

Workflows in general are a very powerful technology within the product.
