Hello!
It is possible for IT administrators to connect to VIP Manager via a front-end (as connected via SAML). Separately, users can be authenticated against a portal (VIP Access Manager, Active Directory Federation Services, and others) that check both first factor authentication against Active Directory and second factor authentication against Symantec VIP (VIP services). As far as I know, these connect with on-premises Active Directory and not Azure AD.
Does this help? If not, can you provide more information about what you are trying to connect?
Thank you!
