To successfully configure aMicrosoft Certificate Authority (CA)inVMware Cloud Foundation (VCF) Operations(formerly vRealize/Aria Operations), the service account used for the integration must have specific permissions on the Certificate Template (e.g., the "VMware" template).

Required Permissions:The VCF 9.0 and Aria Operations documentation explicitly states that the service account must be assignedReadandEnrollpermissions on the target Certificate Template.

Read:This permission is critical for the "Discovery" and "Validation" phase. It allows VCF Operations to query the CA, list available templates, and read the template's properties (like Key Usage and Extended Key Usage) to ensure they meet the security requirements (e.g., Server Authentication, Non-Repudiation).

Enroll:This permission allows the account to actually submit a Certificate Signing Request (CSR) via the interface and receive a signed certificate.

The Cause of Failure (Option A):If the user account is configured withonly the "Enroll" permission, it effectivelylacks the "Read" permission. Without "Read", VCF Operations cannot "see" or validate the template during the configuration wizard. The application attempts to fetch the template details, fails (because the template is invisible to it), and throws the error"Certificate authorities update failed."

Why other options are incorrect:

Option D (Read and Enroll):This is thecorrectand recommended configuration. If the user had these permissions, the operation would succeed (assuming other prereqs like Basic Auth are met).

Option C (Autoenroll):TheAutoenrollpermission is designed for Windows Group Policy-based background renewal. It isnot requiredfor the VCF Operations API-based integration, which relies on explicit "Enroll" calls.
