Ok I was eventually able to figure this out through a lot of trial and error as the docs don't really lay this whole thing out too well.  I had the user id and wanted to get the first and last name for that user.  Your query string for the PortalQueryParameters just needs to be the user id.  There really isn't a query you need to form here if it's that simple.  You then get a user back and you can hit the FullName property from there. Thanks for pointing me in the right direction Joe.  Appreciate it ... PortalQueryParameters userParams = new PortalQueryParameters(<User ID>); PortalQueryResultSet<PortalUser> users = await Portal.FindUsersAsync(userParams); string fullname = users.Results.ElementAt(0).FullName; ...

Thanks for the feedback Michael.  We are still using ArcMap MXDs as our source for feature services.  We have customers that do not have portals federated with ArcGIS Server so we need to support publishing directly to ArcGIS Server for our customers who do not have that architecture.  Lowest common denominator type of thing.  We are also not generating mobile map packages from our feature services - just SQLites.  So I think I'm out of luck on this for now then ... ...

We had a little breakthrough late yesterday.  We are now using straight REST API calls to get the token against the feature service and then applying that token to an ArcGISTokenCredential object.  We can supply that object to the geodatabase create and sync calls.  Seems like a franken-solution, but it's working so we're going with it for now.  There has to be a way to accomplish all this through the Runtime API, but we weren't able to put all the puzzle pieces together correctly for an IWA portal.  Thanks for all your input though Joe. ...

Hey Joe.  So I am now able to get a token successfully in a WPF app, but continually get 401 errors with the same code in a Xamarin Forms app.  I feel like there is a small piece of the puzzle missing on the Forms side.  I believe you are right in saying it is not a Portal issue.  I'm wondering if it is something at the IIS level since the creds are passed through automatically in Windows and not in iOS or Android.  We've played around with a few settings and have had no luck so far.  We also have a Esri support ticket opened on this.   ...

I just tried that Joe and it worked fine.  Took my windows credentials and logged me in. ... View more

Hey Joe thanks for the reply.  I went ahead and tried the brute force approach and tried to generate a TokenCredential object from my user credentials right before generating an offline geodatabase from the feature service.  More or less doing it the same way you are, and I am currently getting a 401 error on that which is really strange.  We are now working with our network dude to see if something is wrong outside of our Portal implementation.  ...

That's a little tough as we've got pieces of all this all over the place, but I'll get you the basics here in no specific order.  What I was after with this post was a recipe.  There has to be a set of steps that has to be taken to log into an IWA portal and be able to make requests against feature services in that portal.  It seems like the ArcGISNetworkCredential gets me in the front door, but doesn't allow me to drink any beers in the fridge if you know what I mean.   AuthenticationManager.Current.ChallengeHandler = new IwaChallengeHandler { AllowSaveCredentials = saveCredentials }; await CreateIwaCredentialAsync(new CredentialRequestInfo { ServiceUri = new Uri(_serviceUri), AuthenticationType = AuthenticationType.NetworkCredential }); ArcGISNetworkCredential credential = await AuthenticationManager.Current.ChallengeHandler.CreateCredentialAsync(credRequestInfo) as ArcGISNetworkCredential; if (credRequestInfo.Response == null) AuthenticationManager.Current.AddCredential(credential); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ using EFCloud.Events; using EFCloud.Security.Managers; using EFCloud.ViewModels;

We pop up a homegrown login page for the user to enter their creds.  That works fine.  My issue is with accessing a feature service on our portal and making a request to that service.  It is complaining about a token when I make that request to the service. ... View more

Thanks Matvei.  This definitely helps. ... View more

Ok that's good to know Jennifer.  So I assume this will be fixed in 100.4 then? No I am not trying to update the geometry before it has been completed.  The scenario I described is where the completed "event" doesn't occur consistently unless I pause before I lift my finger off the screen on a drag and drop. ...
