OAuth2 - SAML on ArcGIS Enterprise - does this give you access to basemaps?
I am creating a WPF application and I am using the simple example online at Display map | ArcGIS Maps SDK for .NET | ArcGIS Developers
If I do not specify an API key then it displays a blank window with Powered by ESRI.
If I specify an API KEY using this code then it displays a map as in the example.
public MainWindow()
{
InitializeComponent();/Esri.ArcGISRuntime.ArcGISRuntimeEnvironment.ApiKey = "AAPKa6a58defb24a41.............dj6-9WIzn5QX_ECKPq52HH8";
}
In my case I am wanting to use OKTA (SAML) authentication to connect to an ARCGIS enterprise system. I have this working using the following code.
ArcGISRuntimeEnvironment.Initialize((options) => { });
string serverUrl = "https://portal.domain.com/portal/";
var clientId = "8qOp0LS.......WwhZ6R";
var serverInfo = new ServerInfo(new Uri(serverUrl))
{
OAuthClientInfo = new OAuthClientInfo(clientId, new Uri(@"vmsUI://auth"), ""),
TokenAuthenticationType = TokenAuthenticationType.OAuthAuthorizationCode
};
AuthenticationManager.Current.RegisterServer(serverInfo);
AuthenticationManager.Current.OAuthAuthorizeHandler = new OAuthAuthorise();
var currentToken = (OAuthTokenCredential)AuthenticationManager.Current.FindCredential(new Uri(serverUrl), AuthenticationType.Token);
if (currentToken == null)
{
currentToken = (OAuthTokenCredential)await Task.Run(async () => await AuthenticationManager.Current.GenerateCredentialAsync(new Uri(serverUrl)), CancellationToken.None);
AuthenticationManager.Current.AddCredential(currentToken);
var portal = await Esri.ArcGISRuntime.Portal.ArcGISPortal.CreateAsync(new Uri(serverUrl), false);
var licenseInfo = await portal.GetLicenseInfoAsync();
var licenseResult = ArcGISRuntimeEnvironment.SetLicense(licenseInfo);
}
In my case the licenseResult returns a property of LicenseStatus: Valid
I can call ArcGISRuntimeEnvironemnt.GetLicense() and it returns the following
If I look at ArcGISRuntimeEnvironment.ApiKey it is set to ""
No map is displayed.
In the output window I see
ArcGIS Maps SDK: Load Error: Basemap
Esri.ArcGISRuntime.Http.ArcGISWebException
Token Required.
ArcGIS Maps SDK: Load Error: Map
Esri.ArcGISRuntime.Http.ArcGISWebException
Token Required.
So finally my question is what do I need to do to get this to work - I must be missing a step with a token but I do not know what.

I have found something very interesting.
I was working with v200.1 (latest version of the runtime) and was mainly using a pretty standard map initializer.
Map myMap = new Map(BasemapStyle.ArcGISImageryStandard);This base map points to
https://basemaps-api.arcgis.com/arcgis/rest/services/styles/ArcGIS:Imagery:Standard
We have another WPF app that was working but it was using 100.15.0 and it used this map initializer
Map myMap = new Map(SpatialReferences.WebMercator) { Basemap = Basemap.CreateDarkGrayCanvasVector() };
You cannot initialize the map in 200.1 using the format above. The method was deprecated even back in 100.15.0 and it tells you to use BasemapStyle.ArcGISDarkGray
But BasemapStyle.ArcGISDarkGray points to
https://basemaps-api.arcgis.com/arcgis/rest/services/styles/ArcGIS:DarkGray
So I changed my test app to 100.15.0 instead of 200.1
My map will show if I use the following initializer
Map myMap = new Map(SpatialReferences.WebMercator) { Basemap = Basemap.CreateDarkGrayCanvasVector() };
but not using BasemapStyle.ArcGISDarkGray
This is what the basemap shows when using CreateDarkGrayCanvasVector - no URI at all is set.
So I assume that our enterprise arcgis server has no base maps and even if it did I would need to specify a basemap which is on the same server and not use the BaseMapStyle which all go to https://basemaps-api.arcgis.com
So I either have to leave the app at 100.15.x and have this basemap or upgrade and have no base map!
