Definition of Enterprise Single Sign-On (E-SSO)

Enterprise Single Sign-On (E-SSO) systems consist of client software and a central database or directory, used to automatically type a user's credentials into application login prompts.

Users sign into the E-SSO client, which authenticates them against a central directory or other infrastructure (e.g., smart cards or hardware tokens).

Users launch applications using icons or a menu displayed by the E-SSO client software. The E-SSO software fetches the user's credentials from the central database, launches the desired application, and uses Windows scripting to send keystrokes representing navigation plus the User ID and password to the application.
