To configure and test Azure AD SSO with FortiSASE SIA, perform the following steps:

  1. Configure Azure AD SSO - to enable your users to use this feature.
    1. Create an Azure AD test user - to test Azure AD single sign-on with B.Simon.
    2. Assign the Azure AD test user - to enable B.Simon to use Azure AD single sign-on.
  2. Configure FortiSASE SIA SSO - to configure the single sign-on settings on application side.
    1. Create FortiSASE SIA test user - to have a counterpart of B.Simon in FortiSASE SIA that is linked to the Azure AD representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

  1. In the Azure portal, on the FortiSASE SIA application integration page, find the Manage section and select single sign-on.
