Azure Active Directory
Configure recipient verification with Azure Active Directory (AD) to allow end-users to sign in to the Barracuda Email Security Service using their Azure AD credentials. Once logged in, users can view their quarantine messages.
You can configure Single Sign-On (SSO) for a domain so that authenticated users can access all or a subset of the restricted resources by authenticating just once using their Azure AD credentials. SSO is a mechanism where a single set of user credentials is used for authentication and authorization to access multiple applications across different web servers and platforms, without having to re-authenticate.
The SSO environment protects defined resources (websites and applications) by requiring the following steps before granting access:
- Authentication: Authentication verifies the identity of a user using login credentials.
- Authorization: Authorization applies permissions to determine if this user may access the requested resource.
