Azure AD with Active Directory Federation Services

  • Last updated on

This article applies to Azure Active Directory (AD) and Active Directory Federation Services (ADFS).

In order for Barracuda Cloud Control to successfully authenticate Azure AD when ADFS is enabled, Azure AD must have access to authenticate using a username/password combination. To do this, use the tool Azure AD Connect.


When configuring Azure AD Connect:

  • Verify you are using the latest version of Azure AD Connect
  • Set user sign-on options to either Password Hash Synchronization or Passthrough Authentication

If you do not meet these requirements, Barracuda Cloud Control cannot authenticate with Azure AD and users will be locked out of the service.

See the Microsoft Azure article Azure AD Connect user sign-in options for more information on Azure AD Connect.
