Unable to configure Single Sign-On on vIDB due to CONFIGURE SSO option greyed out

Products

• VCF Operations

Issue/Introduction

•  The CONFIGURE SSO option is greyed out in VCFOPS under Manage > Identity & Access > VCF SSO Overview:
  
  
  
  
• Duplicate certificates for the vCenter adapter were present in the environment under Operate > Administration > Control Panel > Trusted Certificates
  
  

Environment

VMware Cloud Foundation 9.1

Cause

Two distinct certificates contained identical endpoints but different thumbprints, causing connection failures during the collection cycle and preventing successful SSO configuration.

Resolution

1. Remove Conflicting Certificates
   
   
   • Navigate to Operate > Administration > Control Panel > Trusted Certificates.
   • Locate the vCenter adapter experiencing the issue and identify the certificates with mismatched thumbprints.
     
     
   • Delete the conflicting certificates by clicking the vertical ellipsis (three dots) next to each one and selecting Delete.
2. Reconnect and Validate.
    
   • Navigate to Operate > Administration > Integrations > Account > Workload Domain.
     
     
   • Click VALIDATE CONNECTION to test the vCenter connection. Ensure the test is successful.
     
     
   • Click SAVE to apply the changes.
     
     
3. Verify the Fix.
   
   
   • Check the SSO configuration to confirm it is active and no longer greyed out.
