So there are several factors in play with this question, so here they are:
SailPoint 8.2 and IQService 8.2
Windows Server 2016
A service Account(Domain Admin)
An interactive User account (Domain admin)
Powershell 5.1 build 14393 revision 4583
So what we have is SailPoint is executing a rule on its end, sending over some information to IQService, and IQService is executing the PowerShell scripts as the service account.
