Running activities outside of Server Admin
The Server Admin login page resets any existing session identifier prior to authenticating the user. As a consequence, session data that is set in applicationinit.aspx is lost if the application needs to redirect to the login page before starting. Because of this, the login must now occur before submitting a form that points to the applicationinit.aspx page.
To make activities available in this way, create a form that points to the applicationinit.aspx file for the activity and posts the information that is normally provided by Server Admin into that file. The following example shows a form definition that allows users to run UNICOM Intelligence Reporter outside Server Admin. The example works as follows:
1 An Ajax request is made to Server Admin to determine whether the user is already authenticated.
2 If the user is already authenticated, the form submits directly to applicationinit.aspx.
3 If not already authenticated, the form submits to the login page to authenticate the user. Once authenticated, the login page redirects back to the sample page.
4 If the referrer is the login page, the form submits directly to the applicationinit.aspx.

If you want to use Windows authentication and do not want users to see the Server Admin login page, you need to ensure that the Survey Tabulation front-endWeb.config file uses Windows authentication and sets SPSS_AllowNTNameMappingto True.
