PowerShell operation or Workflow script fails with incorrect ExecutionPolicy setting

Overview

PowerShell executes under a series of ExecutionPolicies that enable different access to different actors in an implementation.

Affected Software

• MIM Event Broker
• PowerShell
• MIM Portal

Symptom

Either individual PowerShell check/standard operations fail with an incorrect ExecutionPolicy message, or a similar exception is thrown when the Portal Workflow script is run.

Resolution

The Execution Policy of PowerShell will need to be updated according to the following prerequisites:

• PowerShell integration that executes within Event Broker executes under a Process Execution Policy Scope.
• The workflow script is not signed as it it generated on request, as such for this script neither the AllSigned or RemoteSigned willl work.
