When using Entra as an SSO source, can I use a self signed Cert for vCenter?

Products

• VMware vSphere ESXi

Issue/Introduction

Customer's configuring Entra as an SSO, may want to test or use a self signed cert with their vcenter.

Resolution

While it is possible to do so, the cert would need to be added to the Microsoft trust store, the same as you would the CA that signs a CA cert.
