Frequently asked questions about Azure AD

  • Azure AD receives ongoing improvements. Stay up to date with the most recent developments by reading our monthly updates, or see the product announcements on the Azure Active Directory Identity Blog.
  • We guarantee at least 99.99% availability of Azure Active Directory Premium services. See the full SLA.
  • Conditional access is a capability of Azure AD that lets you implement automated access-control decisions for accessing your cloud apps based on conditions. Conditional access policies are enforced after the first-factor authentication has been completed. It’s not intended as a first-line defense for scenarios like denial-of-service (DoS) attacks, but it uses signals from these events to determine access.
  • Implement single sign-on for your hybrid environment by configuring password hash synchronization or using federation solutions such as Active Directory Federation Services. With Azure AD Premium, you also get health monitoring for your on-premises identity infrastructure and synchronization services.
  • Azure AD is the built-in solution for managing identities in Office 365. Add and configure any application with Azure AD to centralize identity and access management and better secure your environment. Configure SSO and automated provisioning depending on your application’s capabilities and your preferences. Learn how to configure single sign-on for a non-gallery application and how to use SCIM to automatically provision users and groups.
  • Yes. Azure AD supports several standardized protocols for authentication and authorization, including SAML 2.0, OpenID Connect, OAuth 2.0, and WS-Federation. It also supports password vaulting and automated sign-in capabilities for apps that support only forms-based authentication. Learn more about authentication scenarios and protocols, and SSO for applications.
