Hi Sundram090-4866,
Any entity trying to access Azure Active Directory (Azure AD) identity services via the TLS/SSL protocols will be presented with certificates from the CAs listed below. If the entity trusts those CAs, it may use the certificates to verify the identity and legitimacy of the identity services and establish secure connections.
The following article should give you a guide as to how to set up Enterprise CA for Azure:

I hope this answers your question.
Thanks.
