If a request to an ArcGIS resource returns an authorization error, the ChallengeHandler, if not null, is called. This challenge handler can return the credential for accessing to the resource.
If the ChallengeHandler is null or if it doesn't return any credential, the Authorization error is returned to the caller as if the request was executed out of the AuthenticationManager.
Thetype exposes the following members.
Gets or sets the component that handles the authorization errors in order to get a valid credential object.
Gets the credentials registered by the Authentication Manager.
Gets the singleinstance. This is the only way to get an IdentifyManager instance.
Gets or sets the component sets the component that handles authorization by a resource owner in an oauth workflow.
Gets the registered servers.
Gets or sets the default suggested lifetime of the token in minutes. This default value can be overridden for a specific credential by setting TokenValidity.
Adds a new Credential the AuthenticationManager will use for accessing the resources.
Returns the token credential for the resource identified by the specified url.
Returns the credential that supports the specified authentication type for the resource identified by the specified url.
Returns information about the server that is hosting at the specified url.
Generates a token credential object asynchronously. You need to provide the service URL. This is a helper method typically called by the UI challenging the user.
|GenerateCredentialAsync(Uri, String, String, GenerateTokenOptions)|
Generates a token credential object asynchronously. You need to provide the service URI, the username and the password. This is a helper method typically called by the UI challenging the user.
Returns a Credential object of the specified type (credentialRequestInfo.AuthenticationType) that can be used to access the secured resource identified by the input url (credentialRequestInfo.Url). If required, the challenge method will be called and should return the expected credential object. If case of Token AuthenticationType, the user is typically challenged for a username and password which are used to generate a token. This method is typically called internally when a request fails due to an "invalid credentials" error.
Register secure servers and the token endpoints. The Authentication Manager makes its best guess to determine the location of the secure server and token endpoint so in most cases calling registerServers is not necessary. However if the location of your server or token endpoint is non-standard use this method to register the location. Additionally if portal uses the OAuth authentication, it needs to be registered by this method.
Removes an existing credential so the challenge handler will be called the next time an access to the resources is needed.
|Hyperlink to Example||Description|
|AuthorMap||This sample demonstrates how to author and save a map as an ArcGIS portal item (web map). Saving a map to arcgis.com requires an ArcGIS Online login.|
|OAuth||This sample demonstrates how to authenticate with ArcGIS Online (or your own portal) using OAuth2 to access a secure web map (or the secured layers it contains). Accessing secured items requires a login on the portal (an ArcGIS Online account, for example).|
|SearchPortalMaps||This sample demonstrates searching a portal for web maps and loading them in the map view. You can search ArcGIS Online public web maps using tag values or browse the web maps in your account. OAuth is used to authenticate with ArcGIS Online to access items in your account.|
|TokenSecuredChallenge||This sample demonstrates how to authenticate with ArcGIS Server using ArcGIS Tokens to access a secure service. Accessing secured services requires a login that's been defined on the server.|
