Integrated windows authentication

View on GitHub

Sample viewer app

Uses Windows credentials to access services hosted on a portal secured with Integrated Windows Authentication (IWA).

Use case

IWA, which is built into Microsoft Internet Information Server (IIS), works well for intranet applications, but isn't always practical for internet apps.

How to use the sample

Enter the URL to your IWA-secured portal in the text field at the top of the screen and click "Search Secure". You will be prompted for a username (including domain, such as username@DOMAIN or domain\username), and password. On Windows it will automatically use your current login credentials. If you authenticate successfully, portal item results will display in the combo box below. Select a web map item and click the "Load Web Map" button to display it in the map view.

How it works

The AuthenticationManager object is configured with a challenge handler that will prompt for a Windows login (username, password, and domain) if a secure resource is encountered.
When a search for portal items is performed against an IWA-secured portal, the challenge handler creates an Credential object from the information entered by the user.
If the user authenticates, the search returns a list of web maps (PortalItem) and the user can select one to display as a Map.
On some platforms, the current Windows account is used by default and a login prompt will not be shown if it can authenticate successfully.

About the data

This sample searches for web map portal items on a secure portal. To successfully run the sample, you need:

Access to a portal secured with Integrated Windows Authentication that contains one or more web map items.
A login that grants you access to the portal.
