LDAP Connection Failure in vRealize Orchestrator after Active Directory Service Account Password Update

Products

• VCF Automation

Issue/Introduction

After updating the service account password in the Active Directory integration within vRealize Orchestrator (vRO) / Aria Automation Orchestrator, the system fails to connect to the LDAP server, resulting in an UnknownHostException error.

Error Message: LDAP Server returned error: An error occurred while attempting to resolve address 'ldaps://:636': UnknownHostException(ldaps://:636: Name or service not known), ldapSDKVersion=4.0.14

Environment

vRealize Orchestrator (vRO) / Aria Automation Orchestrator 8.18.x

Cause

The Active Directory plug-in server configuration in vRO was not re-initialized after the service account password update. This leaves stale configuration parameters in memory, causing the integration to attempt connection using outdated session/server parameters, which prevents proper LDAPS host address resolution.

Resolution

Resolution: 

To resolve this issue, you must update the Active Directory server configuration within vRO to refresh the connection parameters:

1. Log in to the vRealize Orchestrator / Aria Automation Orchestrator Client.
2. Navigate to Workflows > Library > Active Directory.
3. Locate and run the Update an Active Directory server workflow.
4. Modify the existing Active Directory server configuration with the updated service account credentials.
5. Verify that the workflow completes successfully.
6. Test connectivity to the Active Directory server to confirm the resolution.
