ADFS 2.0: Configuring Single Sign On for Secured Signing using Active Directory Federation Services

Setting up active directory federation services for use with Secured Signing will allow the nominated users within your domain to use the Secured Signing service using their network credentials. When the single sign on option is enabled in Secured Signing, logged in users will not need to enter their username and password in Secured Signing.

 

The configuration process requires:

  1. Activation and configuration of federations services within Active Directory
  2. Add Secured Signing as a relying party trust in ADFS
  3. Configuration of your Secured Signing membership to accept authentication against Active Directory using federation services.

Once the user has logged in with ADFS successfully, the user will be redirected to Secured Signing. On subsequent logins, the user’s domain name will be remembered. Click “Log in with ADFS” the user will be logged in to Secured Signing using the domain name to login.

Please notice that, with this option, you should logon to windows with your own account to login with ADFS. Otherwise, you may see an error saying “Cannot login, use your own computer to retry or contact your administrator.”.
