Smarts NCM: Push job fails when "Prompt User" & "Run Upon Operator's Initiation" are selected; Error: Failed to decrypt job credential

Products

• VMware Smart Assurance

Issue/Introduction

Symptoms:


Unable to perform push jobs

We use Prompt User under Scheduled Credentials Configuration Option.  There are no issues when using Run Upon Approval method, the issue occurs when we select Run Upon Operator initiation. Both methods are available under Prompt User Configuration.

Environment

VMware Smart Assurance - NCM

Cause

The reason this happens is because it's not able to decrypt job credentials and send data properly to DS. Following are the errors seen in powerup.log.
