I'm trying to use the DotNetOpenAuth library to login programmatically from an aspx page. To start with, I'd like to just be able to login using a 3rd party openid provider like myopenid.
My website is an ASP .NET 4 web forms site hosted in IIS 7.5 hosted at port 9980. This port is open (inbound and outbound) in the computer's firewall.
I'm trying to use the OpenIdLogin login control but I keep getting a ProtocolException saying "No OpenID endpoint found"
I've already added this to web.config/system.net
<defaultProxy enabled="true" useDefaultCredentials="true">
<proxy autoDetect="True" usesystemdefault="True" />
</defaultProxy>
Here's the funny part, the samples themselves are working fine. Any ideas?
-Thanks!
Turn on logging and see what it says. It often gives much more detail about why no endpoints were found.
Well, I found the problem. It is an issue with the corporate firewall/proxy blocking outbound connections.

I have an Asp.net MVC application, which is connected to many Asp.net Web Api services.
It consumes the services using HttpClient requests. These methods exists in SDK libraries.
Is it possible to inspect (sniff) the REST requests, and before being sent, to add additional information in the Headers?
All the Asp.Net Web APIs are on the same local network as the Asp.net MVC application.
I am not sure why do you call the REST api from the ASP.NET MVC controllers, you can call it directly from the Views using jQuery Ajax.
As for the inspection, you can do it using Fiddler, but you will have to update web.config for your ASP.NET MVC application by changing the default proxy like below:
<system.net>
<defaultProxy
enabled = "true" useDefaultCredentials = "true">
<proxy autoDetect="false" bypassonlocal="false"
proxyaddress="http://127.0.0.1:8888" usesystemdefault="false" />
</defaultProxy>
</system.net>
Make sure the proxy port for Fiddler is not changed from the default one 8888
I am just trying to see how open auth works in asp.net 4.5 application.
I just created a new template and it has the deafult code for handling google.
I just un commented the comments as per instructions to enable it, but when i run the application and click on login, it is throwing an exception instead of redirecting to google login page
I have to cross the proxy to make the outbound requests. I guess it is what is blocking it to connect to google.
Is there any way to cross through proxy and make the request ? please suggest
If you are using a proxy then you will need to tell ASP.NET which proxy it should use - this is to do with .NET rather than DotNetOpenAuth. As mentioned by #IsThatSo have a look at Specifying a proxy to use with DotNetOpenID which details that you how you specify the proxy to use.
system.net>
<defaultProxy>
<proxy
usesystemdefault = "False"
proxyaddress="http://myproxyserver:8080"
bypassonlocal="True"
/>
<bypasslist>
<add address="[a-z]+\.mydomain\.com"/>
<add address="[a-z]+\.myotherdomain\.com"/>
</bypasslist>
</defaultProxy>
</system.net>
I have three systems running on IIS7 with static IP address 192.168.66.5. I have configured the system to run on the same IP address with different ports and subdmain like;
192.168.66.5:81 hostname ams.tpf.go.tz
192.168.66.5:82 hostname gmis.tpf.go.tz
192.168.66.5:83 hostname records.tpf.go.tz
192.168.66.5:84 hostname cmis.tpf.go.tz
I configure all these on IIS7 and defined them in the router.
When the client opens ams.tpf.go.tz without specifying the port number, the error 404 is returned: the requested resource is not found.
This recently occurred to me also - make sure your IIS Website is started - mine had been stopped. This is the error I was receiving in Visual Studio:
Unable to start debugging on the web server. The web server could not find the requested resource.
Right Click on your Website (i.e. Default Website) in IIS Manager and click Manage Web Site --> Start.
Navigating to any applications in the IIS Website was showing this error:
HTTP Error 404. The requested resource is not found.
The easiest way to achieve this is to set the port 80 for the site you want to be the "default" one, since this is the default HTTP port.
Some times IIS Manager -> Manage Web Site -> Start, will not work if the below 2 services are not running
1. Windows Activation Technologies Service
2. World Wide Web Publishing Service
Start these services manually under windows services then start IIS again.
Another cause that happens to me with some frequency is to set the permissions correctly to the physical directory. It can be achieved going to IIS -> clicking on the website and then in the actions panel click over Edit Permissions. Be sure that the user you are going to assign the permissions, are the same as defined on Authentication -> Anonymous Authentication or ASP.NET Impersonation, if any of those authentication methods are enabled.
To know the user assigned on those authentication methods, go to the Authentication icon, select any of the authentication methods mentioned before, right click on it and select edit. After that, you have the option to select the user you want.
Hoping this helps.
My issue for anyone else that comes here from google. I am hosting a django website so in my webconfig file it is set to process requests using the python virtual environment. In the web.config file it is this portion:
<configuration>
<system.webServer>
<handlers>
<add name="Python FastCGI"
path="*"
verb="*"
modules="FastCgiModule"
scriptProcessor="C:\inetpub\wwwroot\receipts\venv\Scripts\python.exe|C:\inetpub\wwwroot\receipts\venv\Lib\site-packages\wfastcgi.py"
resourceType="Unspecified"
requireAccess="Script" />
</handlers>
...
</configuration>
When there was requests to the media folder IIS would say great I know what to do send it through the scriptProcessor (python processor). Requests to the media folder should not do that they only need to serve static files (no extra processing). I placed this web.config in the media directory and it solved my problem!
<configuration>
<system.webServer>
<handlers>
<!-- this configuration overrides the FastCGI handler to let IIS serve these static files -->
<clear />
<add name="StaticFile"
path="*"
verb="*"
modules="StaticFileModule"
resourceType="File"
requireAccess="Read" />
</handlers>
</system.webServer>
</configuration>
In my case IIS server and resolved with the below steps.
Check the security groups - whether we have opened the required ports from ALB SG to EC2 SG.
Login to server and check does IIS server's default site has 443 port opened if your health-check is on 443. (whatever port you are using for health checks).
Use the curl command to troubleshoot the issue.
If you would like to check on HTTPS use the below command to check the response. Use -k or --insecure to ignore the SSL issue.
curl https://[serverIP] -k
For HTTP test use the below command.
curl http://[serverIP]
I used google map static api to get map image, but I got an error "The remote name could not be resolved:'maps.googleapis.com'" when executing using (HttpWebResponse response = request.GetResponse() as HttpWebResponse).
But I can got image of google map in windows application(same code with web application), I don't know what happened
This thing is happen due to proxy setting in your system.Please add this code in your web.config file and it will work.
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true">
</defaultProxy>
</system.net>
The problem can go from invalid url (hostname) to your firewall or proxy blocking the request or even misconfigured host file or DNS.
I also faced same issue.
If you are connected with local area network and protected by Proxy server then Go in google chrome settings.
Our system takes default settings from google chrome.
In settings of chrome, go in proxy settings.Click on Lan setting.Click on proxy setting checkbox and click as well on by pass proxy server for local addresses.Also fill details of your proxy server in textbox.
Go in advance and in exceptions field type localhost.Run project again.It will work.
I have four different server and a load balancer. I want to use captcha control. I did something with it this way:
I created a handler.ashx to create the captcha image. This handler is used in the Main page. I keep the captcha control password in session while creating the captcha control. Then I compared password typed by the user with the password in the session. It works very well, but only on one server.
It doesn't run correctly with four servers. Although the user enters the correct password every time, it sometimes matches with the session password and sometimes doesn't match. I think the problem reason is this:
For Example :
A,B,C and D are the four servers. The load balancer routes the first request to A server. Which opens the main page from A server and creates password '123456'. This is stored in session on A server. Then user typed in the password and clicked button. Now the load balancer routes this request to the B server. Because session in B Sever is null, the passwords don't match.
My web.config has this,
<sessionState mode="StateServer" stateConnectionString="tcpip=127.0.0.1:42424"/>
But It still doesnt work.
What should I do ?
So first thing (just to make sure) - I believe that this connection string is just an example because 127.0.0.1 is localhost and it wouldn't have chance to work ;).
Now I will assume that you have chosen server A for you state server. Please check following things:
"ASP.NET State Service" is up and running on the server A (it's disabled by default, you can check that in Administrative Tools --> Services)
the stateConnectionString in servers B, C and D is "tcpip=[Server A IP Address or Network Name]:42424" (it can be 127.0.0.1 only on server A)
servers can communicate between each other using TCP/IP via port 42424 (firewalls etc.)
Please remember that if you have changed configuration of "ASP.NET State Service" on server A to not use default port (42424), you must reflect that in your connection strings.
Sometimes it's easier to configure "SQL Server Mode" instead of "State Server Mode" so you might want to consider that. You can find more details here.
You need to use StateServer or SqlServer for managing the session state and they should be out of your firewall network that is used to balance the load.
http://www.hanselman.com/blog/LoadBalancingAndASPNET.aspx
When using Session State Server, there are few things which need to setup.
Setup ASP.Net State Service on the machine which you want as a StateServer.
net start aspstate
Change Session Mode in Web.Config File for all web applications and point to a StateServer
<system.web>
<!-- ... -->
<sessionState
mode="StateServer"
stateConnectionString="tcpip=your_server_ip:42424"
cookieless="false"
timeout="20" />
<!-- ... -->
</system.web>
3 . All Web Server the use same <machinekey> configuration
<machineKey
validationKey="1234567890123456789012345678901234567890AAAAAAAAAA"
decryptionKey="123456789012345678901234567890123456789012345678"
validation="SHA1"
decryption="Auto"
/>
(Note:To maintain session state across different Web servers in the Web farm, the application path of the Web site (for example, \LM\W3SVC\2) in the Microsoft Internet Information Services (IIS) metabase must be the same for all of the Web servers in the Web farm. The case also needs to be the same because the application path is case-sensitive.
