The VCF Diagnostic Tool for vSphere (VDT) results list "STS connection string is incorrect"

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

After running the VCF Diagnostic Tool for vSphere (VDT) on a vCenter Server, the "IDENTITY SOURCE CHECKS" section lists the following failure:

• [FAIL]    STS connection string is incorrect (ldap://<fqdn_of_vCenter_Server>:389)
                      Note:     This could prevent services from starting after a recent decommission of another vCenter
                      Documentation:     https://knowledge.broadcom.com/external/article?articleNumber=323195

Environment

• vCenter 7.x
• vCenter 8.x

Cause

The STS connection string is not set to the correct value of 'ldap://localhost:389', and will need to be corrected in order to prevent potential problems after the incorrectly referenced vCenter node is shutdown or decommissioned.

Resolution

Follow the Resolution steps in KB article 323195 to set the STS connection string to the default setting.

• vCenter services vapi-endpoint and vpxd-svcs fail to start with "Unexpected status code: 404"
