Error "Authentication Error" and unable to log in to VMware Cloud Director Availability (VCDA) using the SAML accounts.

Products

• VMware Cloud Director

Issue/Introduction

• Login to VMware Cloud Director Availability (VCDA) using the same SAML-authenticated accounts results in an "Authentication failure" error.
• SAML has been configured on the VMware Cloud Director (VCD) provider portal to enable Multi-Factor Authentication (MFA) using Duo.
• SAML and MFA login to the VCD provider portal is working as expected using system administrator credentials.
• The user account being used has all the necessary permissions assigned.
• SAML authentication is successful on VCD but fails when attempting access to VCDA with the same credentials and configuration.

Environment

VMware Cloud Director Availability 4.7.x

VMware Cloud Director 10.6.x

 

Resolution

The standalone UI of VCDA does not support this type of integration. However, the VCDA plugin within the vCloud Director portal can be used after logging in through your preferred authentication method.

Ensure that Cloud-to-Cloud Challenge Authentication is enabled on both VCD sites.
