About form-based client-initiated SSO authentication

With the HTTP form-based client-initiated method of authentication, when Access Policy Manager detects the request for a logon page (URI, header, or cookie that is configured for matching the request), APM generates JavaScript code, inserts it into the logon page, and returns the logon page to the client, where it is automatically submitted by the inserted JavaScript. APM processes the submission and uses the cached user identity to construct and send the HTTP form-based post request on behalf of the user.

Basic configuration of form-based client-initiated SSO

To create a form-based client-initiated SSO configuration object, you must configure at least one form and include at least one form parameter. A form parameter represents an input element on an HTML logon form, such as a form field for entering a user name or password, or, optionally, for entering a hidden form parameter.

Form-based client-initiated SSO configuration supports three sets of matching criteria that you can define.

  • Form Detection (Required) Configures the SSO module to detect the HTTP request for the logon page by matching the HTTP URI, header, or cookie that you specify, and supports entry of multiple URIs. Requires data that is specific to the application. Form detection is successful when the request matches one of the configured items either partially or fully, depending on whether Request Prefix is enabled in Advanced Properties .
  • Form Identification (Optional) Specifies how to detect the form within the HTTP body of the logon page. The default is form parameters, which enables identification of the logon form parameter fields based on the values entered for the form parameters in the General Properties. Alternatively, you can specify that the form be identified using other data present in the form, such as the ID, name, or action attributes, or the form order.
  • Logon Detection (Optional) Configures the SSO module to detect whether logon was successful by checking for the presence of a cookie or a redirect URI. The default is None (logon detection is not performed).

The majority of web applications have a single logon page with one logon form. You need to define a single form for these applications. In less usual cases when an application has multiple logon pages with different logon forms, you need to create multiple forms, one for each logon page. If multiple logon pages use the same form, you need only one form with a list of URIs for all logon pages.

How does form-based client-initiated SSO authentication work by default?

This figure illustrates the default behavior of the form-based client-initiated SSO authentication method.

Form-based client-initated SSO Default Behavior Form-based client-initiated SSO default behavior
  1. The user logs on to Access Policy Manager and APM runs the access policy. This populates the session variables with the user credentials.
  2. The user requests the application logon page. This GET request is passed to the application web server, verbatim.
  3. The application web server replies with 200 OK and serves the logon page.
  4. APM generates JavaScript and inserts it into the logon page before returning it to the user. The JavaScript assigns values to form parameters, as specified in the form configuration. The password parameter is assigned a password token rather than the actual user password.
  5. The JavaScript runs on the client side. The logon page is not displayed to the user; user input is locked out. Without delay, the form is submitted using POST. The form parameters and their values, including user name and password token, are sent to APM.
  6. APM then replaces the password token with the actual user password, as well as other form parameters specified in the form configuration with their configured values.
  7. The POST, along with the real user credentials from step 1, is sent to the web server.
  8. The application start page is served by the webserver, and sent to the client, verbatim. Optionally, APM performs detection of successful logon by examining HTTP response headers, looking for a cookie or redirect Location URI.

About advanced configuration options for form-based client-initiated SSO authentication

You can change some aspects of the form-based client-initiated SSO default behavior by configuring optional properties.

  • You can change the default properties for form request and form submittal using advanced properties.
  • You can change the automatically generated JavaScript code that is inserted into the logon page in one of three ways using the JavaScript Insertion options. You can replace it completely with custom code or add extra code to it by specifying the application JavaScript functions to call prior to submitting a logon form.
  • You can configure the SSO module to automatically detect the application HTTP request that submits user credentials using Form Submit Detection. If you disable automatic detection, the SSO module instead detects form submittal by using an HTTP header, cookie, or HTTP URIs that you specify.

Configuring form-based client-initiated SSO

You can use the form-based client-initiated SSO method to create form-based SSO configurations. For example, you can use this SSO method to support web applications that run JavaScript in the browser and need to maintain application state during the login process. You can also use it to support web applications that present multiple login screens.
  1. On the Main tab, click Access Policy > SSO Configurations > Forms - Client Initiated. The Forms - Client Initiated screen for SSO configurations opens.
  2. Click Create. A screen, Create New Forms-Client Initiated Configuration, opens.
  3. In the SSO Configuration Name field, type a name.
  4. Select Form Settings from the left pane. Fields in SSO Configuration displays in the right pane.
  5. Click Create. The Create button is not active until you complete they General Settings by typing a name for the SSO configuration.
    Note: You must create at least one form to complete the SSO configuration.
    The Create New Form Definition screen opens.
  6. Type a name in the Form Name field.
  7. Select Form Parameters from the left pane. Form Parameters displays in the right pane.
  8. For each form parameter that you want to create, repeat these steps:
    1. Click Create. The Create New Form Parameter screen opens.
    2. In the Form Parameter Name field, type or select a name.
    3. In the Form Parameter Value field, type or select a value.
    4. Click OK.
    The screen closes, showing the Create New Form Definition window, which displays the new form parameter.
  9. Click Form Detection from the left pane. The right pane displays required fields.
  10. From the Detect Form by list, select an option and type required data.
    • URI Type a URI in the Request URI field.
    • Cookie Type a name in the Cookie Name field.
    • Header Type a name in the Header Name field.
    The OK button is available.
  11. Click OK. You can create another form next or you can save the configuration. The new form is created. Its name displays on the Create New Forms-Client Initiated Configuration screen.
  12. Click OK. The screen closes, displaying the Forms - Client Initiated screen for SSO Configurations.
The new form-based client-initiated SSO configuration is available for use.
