Configure and test Azure AD single sign-on

In this section, you configure and test Azure AD single sign-on with Mimecast Personal Portal based on a test user called Britta Simon. For single sign-on to work, a link relationship between an Azure AD user and the related user in Mimecast Personal Portal needs to be established.

  1. Configure Azure AD Single Sign-On - to enable your users to use this feature.
  2. Configure Mimecast Personal Portal Single Sign-On - to configure the Single Sign-On settings on application side.
  3. Create an Azure AD test user - to test Azure AD single sign-on with Britta Simon.
  4. Assign the Azure AD test user - to enable Britta Simon to use Azure AD single sign-on.
  5. Create Mimecast Personal Portal test user - to have a counterpart of Britta Simon in Mimecast Personal Portal that is linked to the Azure AD representation of user.
  6. Test single sign-on - to verify whether the configuration works.
