I noticed the linkedin authentication provider is in the DNN source, but it doesn't seem to be working/finished.

is there an ETA when the linkedin authentication provider will be ready?

 

Thanks

I was also wondering when this will be available.... Source code has been there for a long time. Is there a reason why this isn't actively developed on, or finished? I tried to load the login provider my self. I does redirect to Linkedin etc but when returning to dnn it fails.

Error in log

Message: DotNetNuke.Services.Exceptions.PageLoadException: There was an error deserializing the object of type DotNetNuke.Authentication.LinkedIn.Components.LinkedInUserData. Encountered unexpected character '<'. ---> System.Runtime.Serialization.SerializationException: There was an error deserializing the object of type DotNetNuke.Authentication.LinkedIn.Components.LinkedInUserData. Encountered unexpected character '<'. ---> System.Xml.XmlException: Encountered unexpected character '<'.

 Which is generated from this function:

public TUserData GetCurrentUser<TUserData>() where TUserData : UserData

One step further:

Noticed that endpoint in LinkedInClient class was:

MeGraphEndpoint = new Uri("http://api.linkedin.com/v1/people/~");

Which returned XML so jsondeserialize fails, so i changed it to this so it works

 

MeGraphEndpoint = new Uri("http://api.linkedin.com/v1/people/~?format=json");


But now i have a new error :)

Message: DotNetNuke.Services.Exceptions.PageLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Services.Authentication.OAuth.UserData.get_FirstName() at DotNetNuke.Services.Authentication.OAuth.OAuthClientBase.AuthenticateUser(UserData user, PortalSettings settings, String IPAddress, Action`1 addCustomProperties, Action`1 onAuthenticated) at DotNetNuke.Services.Authentication.OAuth.OAuthLoginBase.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace ---

And yet another step :)

Changed it to this:

MeGraphEndpoint = new Uri("http://api.linkedin.com/v1/people/~:(id,first-name,last-name,email-address,formatted-name)?format=json");

RequestTokenEndpoint = new Uri("https://api.linkedin.com/uas/oauth/requestToken?scope=r_emailaddress");

This way you have the needed id. At this point I'm able to login successfully (although it displays error). Probably this is because the firstname, lastname, email is not serialized.
