The single-sign-on (SSO) feature allows you to configure View Manager so that end users are prompted to log in only once.

If you do not use the single-sign-on feature, end users must log in twice. They are first prompted to log in to View Connection Server and then are prompted log in to their View desktop. If smart cards are also used, end users must sign in three times because users must also log in when the smart card reader prompts them for a PIN.

For View desktops, this feature includes the Graphical Identification and Authentication (GINA) dynamic-link library for Windows XP and a credential provider dynamic-link library for Windows Vista, Windows 7, and Windows 8.
