After configuring the multi-node plugin in Aria Automation Orchestrator, the inventory objects are not visible.

Issue/Introduction

After setting up the multi-node plugin in vRealize Orchestrator (vRO), users are unable to view inventory objects from the remote vRO server or execute workflows that interact with it. This issue is typically indicated by 401 Unauthorized errors appearing in the vRO application logs when the multi-node plugin attempts to access resources from the remote server.

Environment

Aria Automation Orchestrator 8.18.x

Cause

The root cause of the 401 Unauthorized error is an authentication mismatch due to the username format used during the multi-node plugin configuration. The plugin was configured using a User Principal Name (UPN) format (e.g., [email protected]), while the target Aria Automation environment's vIDM integration is configured to expect the username in sAMAccountName format (e.g., username), which does not include the domain component.

Since the vIDM/Aria Automation authentication integration is configured to validate credentials based on the sAMAccountName attribute, any login attempts made with the UPN format are rejected, resulting in the 401 Unauthorized error. This prevents the multi-node plugin from establishing a valid session and accessing inventory or executing remote workflows.

Resolution

To resolve this issue, reconfigure the multi-node plugin connection using the username in sAMAccountName format.
