I have a workflow set up with an approval step that is sent to a group. Any
member of that group can log in to the userapp and approve the request. I
would like to get the DN of the specific user that did the approval (not the
group DN, but the user DN that approved it) and place that DN into an
attribute on the recipient's user object.

I'm assuming that I need to use an Entity step after the approval step, but
inside that entity step, how do I get the DN of the approving user? Is this
the correct way to do this?

Thanks!
