Jethro Seghers presented on Azure Active Directory. Azure AD is a comprehensive identity and access management cloud solution that combines directory services, identity governance, application access management, and a developer platform. It allows for single sign-on, self-service access, and synchronization of identities from on-premises directories to the cloud. Azure AD supports cloud identities stored directly in Azure, federated identities using AD FS, and pass-through authentication to keep identities on-premises while authenticating to Azure.
