For more information, go to List deployed archives.

Changes to the OpenIDConnect service configuration

Starting from GAS and FGLGWS versions 3.21.02, 4.01.07, and 5.00.02, two parameters of the Genero OpenIDConnect service configuration ($FGLDIR\web_utilities\services\openid-connect\res\configuration) have changes:

  • The oidc.logout.id_token_hint parameter, used in the logout request sent to the provider, has been replaced by oidc.logout.identifier. The new parameter supports the values "id_token_hint", "client_id", or an empty (" ") value. The default value is "id_token_hint".
  • The oidc.logout.post_redirect parameter, used to send the post redirect uri in the logout request, now needs a string value instead of the boolean value true/false on previous versions. The default value is now "post_logout_redirect_uri".

No action needs to be taken on your part, but if you have previously used a custom OpenIDConnect configuration file and you want to use it when upgrading FGLGWS version, ensure that you review your configuration for these parameters.

For more information on OpenID Connect Single sign-on, go to OpenID Connect/OAuth2 SSO.

New option to list session ids in the gasadmin session command

Starting from GAS 3.21.02, GAS 4.01.07, and GAS 5.00.02, the gasadmin session command has been enhanced with an option, --list-session-ids, to output just a list of identifiers of the active sessions. No proxy details are output, such as the names of the applications or services, as in the output from the gasadmin session --list-sessions command.

For more information on gasadmin session commands and examples, go to gasadmin.

New option to count sessions in the gasadmin session command

Starting from GAS 3.21.02, GAS 4.01.07, and GAS 5.00.02, the gasadmin session command has been enhanced with an option, --count-sessions, to return a count of the number of active sessions (applications and services).

Changes to the IIS server configuration for authentication

Starting from GAS 3.21.02, GAS 4.01.07, and GAS 5.00.02, it is recommended that you set the Manage Pipeline mode application pool setting to "Integrated" instead of "Classic". Where previously you used "classic", and now your application relies on an authentication token passed from IIS to the runtime, you may find this process breaks your application. This is due to the new architecture in IIS (introduced in IIS 7), which works in an integrated way with different IIS modules.

By setting to "Integrated", now the IIS will switch context to whatever IIS and ASP.NET modules it needs to call to handle application requests. However, be sure to test your existing applications for compatibility in Integrated mode before upgrading application pools in a production environment to Integrated mode.

For more information on IIS configuration, go to Create application pool. For more information on Microsoft® recommendations for use of integrated mode, refer to Learn IIS.
