Connect to Portal to give users access to their organization’s basemaps.

Use case

Organizational basemaps are a Portal feature allowing organizations to specify basemaps for use throughout the organization. Customers expect that they will have access to their organization’s standard basemap set when they connect to a Portal. Organizational basemaps are useful when certain basemaps are particularly relevant to the organization, or if the organization wants to make premium basemap content available to their workers.

How to use the sample

You’ll be prompted to load a portal anonymously or with a log-in. After you sign in, you’ll see thumbnails for these basemaps shown in a picker. Select a basemap to use it in the map.

How it works

  1. The user is prompted to load a portal anonymously or with a log-in.
  2. A Portal is then loaded.
  3. If the user chose to log-in in step 1, this uses OAuthUserConfiguration.
  4. An OAuthUserConfiguration is created with the portal URL, a client Id and a redirect URI corresponding to the portal.
  5. The OAuthUserConfiguration is added to the Toolkit’s OAuthUserConfigurationManager in order to opt-in to receiving OAuth challenges.
  6. When the app launches, the portal is loaded, which triggers an authentication challenge.
  7. An Authenticator listens to the challenge and displays a login screen to allow user credentials to be entered.
  8. If the user chose to load a portal anonymously, all OAuthUserConfiguration are cleared.
  9. After a successful load, get the list of basemaps: portal::fetchBasemapsAsync()

Relevant API

  • Authenticator
  • Authentication::OAuthUserConfiguration
  • OAuthUserConfigurationManager
  • Portal
  • Portal::fetchBasemapsAsync

Additional information

This sample uses the OAuthUserConfigurationManager toolkit component and requires the toolkit to be cloned and set-up locally.

See Customize basemaps in the Portal for ArcGIS documentation to learn about customizing the organization’s basemap list in a portal.
