MIM 2016 SP1 PAM request privileged on behalf

Hi colleagues,

is it possible to request privileges using MIM PAM or the MS PAM Portal (Github) on behalf of a user?

My idea is to have a unprivileged user logged in to a PAW and request privileged roles for his differen users in tier 0, tier 1 oder tier 2.

As far as I understand the MIM PAM system I can only request privileged roles for my self (my priv user in the bastion forest), right?

Maybe someone can help me with this question or push me into the right direction.

Thanks

Chris
