I need a little help with the C# example program of Google-Drive...
I used this so-called "tutorial"/"example":
https://developers.google.com/drive/examples/dotnet
And the code from here:
https://code.google.com/p/google-drive-sdk-samples/source/checkout
I uploaded my (only slightly modified) sourcecode here in case anybody doesn't have Mercurial (I didn't have Mercurial and no admin rights to install it either, and Mercurial is the only way to get the sourcecode...):
http://verzend.be/elt0k13enraw/DrEdit.rar.html
I always get
"Ressource cannot be found"
Requested URL: /oauth2callback
I don't find this astonishing, as no oauth2callback controller or handler is implemented...
I tried adding a Controller called oauth2callbackController and redirecting to another action in oauth2callbackController.Index, doing
return new RedirectResult("/about/about");
But that only creates a NULL-reference exception.
So i figured, maybe the wrong controller and redirected to
return new RedirectResult("/drive/Index");
But that only creates an infinite loop of redirect -> allow -> redirect - allow -> etc.
BTW, the config to change the API key + REDIRECT_URI is in
Models\ClientCredentials.cs
Note:
The problem aren't my modifications.
The sample also didn't work unmodified, with the exact same error.
All I did was removing EntityFramwork references, and throwing "Not implemented exception" when a method using entity was called.
Edit:
Additional information:
What I really wanted to do in the first place is to write a console service that exports my database, LZMA-compresses the exported content, encrypts that with OpenPGP, and uploads the database of my server to Google drive every day at 24:00 o'clock, without any user input.
I got export working without a problem, i got the LZMA compression working without a problem, I got the encryption with PGP working without a problem.
After the end of the working day (grrrr), when I was at home, I was even able to download the example-code with the mercurial installed on my Linux-machine at home, and bring it on the windows machine using SMB...
But now I can't get the sample for the Google-drive SDK working...
And moreover, what I really need is an example for a console service/daemon, not a web-application.
When I created the API key, I saw one could create a key for a service, but there is no example on how to write a Google-Drive service (console application), and no useful documentation as well (yea there is a reference, but it's only a reference, IntelliSense provides about the same)...
When configuring your app in the API Access tab of the APIs Console, you had to set the root (/) of your web server as the redirect URI and not /oauth2callback.
Assuming that your app is published at www.example.com, just go back to the APIs Console and set it to www.example.com instead of www.example.com/oauth2callback

I am trying to use Identity Server 4 for Authenticationa and authorization purpose but which ever project i try to run is throwing only 1 error which is like bugging me alot because i have search for this error and i cant find a stable and proper solution for this.
Error :
Error connecting to
http://localhost:5000/.well-known/openid-configuration: An error
occurred while sending the request.
Couple of projects in which i am getting same error and dont know how to solve it :
https://www.dropbox.com/s/9hs3huwt8h035ek/oauth2Demo-master.rar?dl=0
Another Project : Download but same error
In my first project it seems like there is some problem related to SSL certificate though i tried to follow below link to install certificate but still this error exist :
https://github.com/IdentityServer/IdentityServer3.Samples/tree/master/source/Certificates
But in my second project there is no such SSL certificate problem but still same error.
Is there any way to resolve that error?
I downloaded the solution and I can confirm you need to make sure to run the OAuth2Demo.IdentityServer project, you can actually start it up and navigate to https://localhost:44305/admin/ to see the admin environment of identityserver. It apperantly also needs a sql connection to store configuration information, I didn't dig into those details but with the OAuth2Demo.IdentityServer running the other projects can also be started.
My suggestion is to get the things done one by one.
From your screens I see that on the first you are trying to reach IDS at localhost:44305, and on the second screen, you are trying to reach it at localhost:5000. It will be a good thing to set it as a constant value ( right click on your Identity Server project ->Properties->Debug->Web Server Settings->App URL) and then use this value through all of your clients.
Then - enable Identity Server logging - check here. You can extend this example - serilog basic configurations. So far logging has saved me many times, so I can say that it is really important. Make sure that the App pool account, running the application has the rights to create files, where you want them to be created.
Now the real problem:
Lets assume that you select localhost:5000 as url for your IDS.
First of all start (debug) only the Identity Server project. This should take you to localhost:5000 and you will see a welcome message from Identity Server 4.
If you see it, this means that your IDS is working. This also means that you will be able to access the Discovery Document - the one thing that is failing in your clients. Now its about time to setup your clients.
If not, this means that there is something wrong with your Identity Server instance, and that is the place to dig.
First thing I'll do is to check the logs. They will say what the problem is.
Then - I figure out that you are trying to use custom certificate for this (correct me if I've misunderstood). Why don't you try using the Developer Signing Credential (check the ConfigureServices of Startup.cs) at least for starting it up.
Later on, if you decide to use your custom certificate, have in mind that the user, that is running the IDS application (by user I mean the application pool user) should have at least read privileges over the certificate (I guess that you've seen that in the article you have provided).
Do all these, and let's see what progress you will have, but most important - enable the logging.
I have a very basic Single Sign On app built on VS 2015 using MVC and Web Forms. It is supposed to be a simple proof of concept and is based on some code found here and here which are essentially the same things. I've finally gotten it all converted to use .Net 4.5 but when running it on my local server it throws a 404 with no debug information.
The 404 itself wasn't initially a surprise as I was supposed to be able to change the url to one of the secure pages (for instance /WebSecApp1) which would redirect me back to the signon page but no matter what I put as the url I get the 404.
I've also tried changing the urls in the code so that they contain the port numbers for the localhost but that doesn't work either.
It was suggested to me that the RouteConfig.cs could be the culprit but I don't see how that could be since I'm calling a single page with no parameters.
I know this is kind of lite on details but does anyone have any suggestions?
Yes this looks like a routing issue as you also thought it to be. Routing is essential for web api too .Pls see https://www.asp.net/web-api/overview/web-api-routing-and-actions/routing-and-action-selection. Does your api request look like this
GET http://localhost:34701/api/products/1?version=1.5&details=1
You do have to mention the port in the request.
While the routing that Arathy mentioned above was partially to blame, the real problem turned out to be relatively simple. In my case simply selecting Properties->Web for each of offending pages and setting "Override application root URL" to checked fixed the whole problem.
I'm using MVC External Authentication providers for both Google and Facebook. I have easily gotten both working many times before.
For some reason today, on a brand new project (File | New Project | MVC 5 Web App) in VS 2015 - it is the completely default project. The only thing I have done is provide the App Keys and Secrets for both Google and facebook.
Facebook works all the way through, calls back - asks me to register as a new user - and then logs me in as that user.
Google gets all the way to the point where it WOULD call back to the OAuth Callback url - but that never happens, and instead I'm just redirected back to the login page with no further explanation. There are no errors, no messages are logged anywhere that I can find, and no exceptions are thrown.
If instead, I register as a password user, and then try to link the account - I am able to do so without any trouble with facebook. However, again, with the Google external provider, it gets to the point where the OAuth callback uri WOULD Be triggered, but instead, it just take me back to the "/ManageLogins" page with the generic error "An Error has Occurred".
I have enabled every type of exception that I could possible trap - but I get absolutely no feedback from the process except that it didn't work. And since I literally have not yet had a chance to write a single line of code, I'm not sure what else to try.
I have spent almost 6 hours now trying to get this basic identity management part of the project completed - and while it usually only takes 10-15 minutes, I am completely blocked. And since there is so little feedback from the code itself, I'm hoping that someone has run into this before and might be able to help.
Thanks.
Other Things I've tried:
1) it was original http - I thought that might be the problem, so I got an ssl certificate - and have converted it to https. Same problem.
2) I have cleared my cookies, tried incognito, tried in many browsers - always the same result.
3) Original it was a new project in a larger solution - so I have now just created a new web project in it's own solution. Same problem.
4) I have switched to 2 different domains, and tried it from localhost of course.
Running out fo things to try....

I know its an old thread, but I ran into the exact same issue. You have to make sure that Google+ API is enabled in Google Developers Console.
I'm using the AllScripts HelloWorld TouchWorks C# Project, as provided on their site. I've also created a valid application, using the svcUsername and svcPassword on the app.config file to log and added my own appName instead of the default web20.
Didnt change anything else, tried with many different application ID's, all trying to log into the default sandbox server in the example and some trying other sandboxes.
Regardless of what I do, I keep getting
Error: Service Application not licensed on this server!
Despite this being a sandbox server, thus suppouseably accessable to all applications.
What did I do wrong?
edit: Tried to do the same in Slueth, I get the same error.
It's more simple than it seems. Sandbox servers DO require licenses. Talked with the staff, they're nice people, so they manually added me after a few explanations of my requirements.
When using WebResource.axd you will see two parameters being passed in the query string. Usually looks something like this:
WebResource.axd?d=9H3mkymBtDwEocEoKm-S4A2&t=634093400273197793
I have run into an issue where I need a permanent link to the resource in question. Recently the link I was using stopped working. What would cause these ids to change? Rebooting the server? Recompiling the code? Is there anyway to make these ids permanent?
Background -
As part of a site monitoring service we are subscribed to, we have "recorded" several sets of user actions for our website. For example, we recorded the process of logging into the site. The monitoring is now saying that the user login process fails (it's working fine) because it cannot find the WebResource.axd with the ids it recorded.
This page provides all the information on the makeup of the URL
http://support.microsoft.com/kb/910442
The "d" stands for the requested Web Resource
Something worth noting is that you don't need to have the timestamp (t) parameter there to call the resource. Try it on your own site, view the source and grab a webresource.axd url and navigate to the it, remove the t
