In my WCF4.5 https web service I want to set authorization to specific users/groups, I.e. I only want certain domain users or groups to be allowed to call my service.
In my web.config I have added the following as a simple test to see if every user is disallowed:
<system.web>
<authentication mode="Windows" />
<authorization>
<deny users="*" />
</authorization>
</system.web>
In my bindings section I have a:
<security mode="Transport">
<transport clientCredentialType="Windows" />
</security>
and a similar entry in my client.
However, when I run my client, it is allowed. So I'm figuring I'm missing something out?
I've read various websites and they either simply mention the above or go into a whole detail about all sorts without a meaningful answer or require hard coding of security in code.
thanks for any help
You need
<allow roles="DOMAIN\Group"/>
Otherwise you deny ALL the users by using <deny users="*" />
<system.web>
<authentication mode="Windows" />
<authorization>
<allow roles="DOMAIN\Group"/>
<deny users="*" />
</authorization>
</system.web>
This are my first steps in programming ap WCF service using a tutorial from the MSDN sites.
What i've done:
creating a service project (ASP.NET Web Application in VS 2013)
creating an Entity Data Model (EF 6) from existing MS sample database (AdventureWorksLT) including a database table
creating the service ("Add New Item", Template "WCF Data Service" Name "AdventureWorksService")
configuring the service by copy and paste the source code for the service from the MSDN site
creating the WPF Client Application by adding a new WPF application template to the solution
add a new data source from type "Service"
in the dialog box "Add Service Reference" i clicked on "Discover"
The created service "AdventureWorksService" appears in the list of available services with the address "http://localhost:53948/AdventureWorksService.svc".
Now i have to click the button "OK" to download the service information. At this point, i receive an error (beware, that I', using a German Visual Studio, so the translation may not match the original message in English Version:
"Error: Cannot obtain Metadata from the address. Make sure, the address is correct"
If i click the linklabel "Details", i get the following informations:
**Error: Cannot obtain Metadata from "http://localhost:53948/AdventureWorksService.svc/_vti_bin/ListData.svc/$metadata".**

--.
Metadata contains a reference that cannot be resolved: "http://localhost:53948/AdventureWorksService.svc".
The contenttype "text/html" of the message doesn't match with the content type of the binding (application/soap+xml; charset=utf-8).
There's no App.config in the service project, but a Web.Config:

I guess it has to do with the HTTP-protocol, which is not defined in the service.

I want to compress my files using GZIP. Can you share the web.config code for compressing files with GZIP?
Is there anything more that I have to do after uploading my web.config file?
GZip Compression can be enabled directly through IIS.
First, open up IIS,
go to the website you are hoping to tweak and hit the Compression page. If Gzip is not installed, you will see something like the following:
“The dynamic content compression module is not installed.” We should fix this. So we go to the “Turn Windows features on or off” and select “Dynamic Content Compression” and click the OK button.
Now if we go back to IIS, we should see that the compression page has changed. At this point we need to make sure the dynamic compression checkbox is checked and we’re good to go. Compression is enabled and our dynamic content will be Gzipped.
Testing - Check if GZIP Compression is Enabled
To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:
Content-Encoding: gzip
If anyone runs across this and is looking for a bit more up-to-date answer or copy-paste answer or answer targeting multiple versions than JC Raja's post, here's what I've found:
Google's got a pretty solid, easy-to-understand introduction to how this works and what is advantageous and not.
https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/optimize-encoding-and-transfer
They recommend the HTML5 Boilerplate project, which has solutions for different versions of IIS:
.NET version 3
.NET version 4
.NET version 4.5 / MVC 5
Available here: https://github.com/h5bp/server-configs-iis
They have web.configs that you can copy and paste changes from theirs to yours and see the changes, much easier than digging through a bunch of blog posts.

Edit: One update if you need Gzip compression on WebAPI responses.
I wasn't aware our WebAPI wasn't returning Gzipped responses until recently and scratched my head for a while because we had dynamic and static compression turned on in web.config. We looked at writing our own compression services and response handlers (still on WebAPI 2 not on .NET Core where it's easier now), but that was too cumbersome for what seemed like something we should just be able to turn on.
(If you're interested here's what we were looking at for our own compression service https://krzysztofjakielaszek.com/2017/03/26/webapi2-response-compression-gzip-brotli-deflate/
EDIT: Link is now offline, but you can view the code/content here: https://web.archive.org/web/20190608161201/https://krzysztofjakielaszek.com/2017/03/26/webapi2-response-compression-gzip-brotli-deflate/ )
Instead, we found this great post by Ben Foster (http://benfoster.io/blog/aspnet-web-api-compression)
If you can modify applicationHost.config (running your own servers), you can pop that config file open and add the mimeTypes you want to compress (I pulled the relevant ones based on what our API was returning to clients from our Web.Config). Save that file, IIS will pickup your changes, recycle app pools, and your WebAPI will start returning gzip compressed responses to clients who request it.
If you don't see gzipped responses, check the response content type with Fiddler or Chrome/Firefox Dev Tools, and ensure it matches what you added. I had to change the view mode (use large request rows) in Chrome Dev Tools to ensure it showed the total size vs transferred size. If everything validates, try rebooting the server once to just ensure it was properly applied. I did have one syntax error where when I opened up the site in IIS, IIS poppped open a message about a parsing error that I had to fix in the config file.

Global Gzip in HttpModule
If you don't have access to shared hosting - the final IIS instance. You can create a HttpModule that gets added this code to every HttpApplication.Begin_Request event:-
HttpContext context = HttpContext.Current;
context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip");
HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true;
Filing this under #wow
Turns out that IIS has different levels of compression configurable from 1-9.
Some of my dynamic SOAP requests have been getting out of control recently. With the uncompressed SOAP being about 14MB and compressed 3MB.
I noticed that in Fiddler when I compressed my request under Transformer it came to about 470KB instead of the 3MB - so I figured there must be some way to get better compression.
Eventually found this very informative blog post
http://weblogs.asp.net/owscott/iis-7-compression-good-bad-how-much
I went ahead and ran this commnd (followed by iisreset):
C:\Windows\System32\Inetsrv\Appcmd.exe set config -section:httpCompression -[name='gzip'].staticCompressionLevel:9 -[name='gzip'].dynamicCompressionLevel:9
Changed dynamic level up to 9 and now my compressed soap matches what Fiddler gave me - and it about 1/7th the size of the existing compressed file.
Milage will vary, but for SOAP this is a massive massive improvement.
This is more an add-on to the best answer above (GZip Compression can be enabled directly through IIS) which is correct if your running IIS on Windows desktop however...
If your running IIS on Windows Server, this content compression feature is found in a different place to desktop Windows (not in programs and features in Control Panel). First open "Server Manager" then click Manage -> "Add Roles & Features" then keep clicking NEXT (make sure you select the correct server when you see the list of servers if your managing multiple servers from this instance) until you get to SERVER ROLES, scroll down to and open "Web Server (IIS)..." then "Web Server" then "Performance" then tick "Dynamic Content Compression" then click INSTALL. I tested this on Server 2016 Standard so there may be slight differences if your on an earlier version of Server.
Then follow the instructions from Testing - Check if GZIP Compression is Enabled
Sometimes no matter what you do or follow whole internet posts. Try on the MIMETYPES of applicationhost.config of the server.

You are encountering a WCF default limit on the message size. To raise the limit, use the maxReceivedMessageSize attribute in your web.config file (server side).
<system.serviceModel>
<bindings>
<basicHttpBinding>
<binding maxReceivedMessageSize="10000000">
</basicHttpBinding>
</bindings>
</system.serviceModel>
This is probably really late, but for anyone else that is also stuck.
The initial problem is solved by what BilalAlam described (increase the maxRecievedMessageSize) but your issue is the bindings need to be tied to the endpoint via the bindingConfiguration in the endpoint and the name in the binding.
Example
<bindings>
<webHttpBinding>
<binding maxReceivedMessageSize="2147483647" name="NAMETOTIEENDPOINT">
<readerQuotas maxStringContentLength="2000000"/>
</binding>
</webHttpBinding>
</bindings>
<services>
<service>
<endpoint address="basic" bindingConfiguration="NAMETOTIEENDPOINT" binding="webHttpBinding" contract="JSONWebService.IService1" />
</service>
</services>
I added
ELMAH to my website and i am getting the following error in my web.config
The inheritinChildApplications has a red squiggly meaning the compiler doesnt like it. and the location path portion is grayed out. Im new to using ELMAH, anyone have any thoughts on how to rectify this?
<location path="elmah.axd" **inheritInChildApplications="false"**>
<system.web>
<httpHandlers>
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
</httpHandlers>
<!--
See http://code.google.com/p/elmah/wiki/SecuringErrorLogPages for
more information on using ASP.NET authorization securing ELMAH.
<authorization>
<allow roles="admin" />
<deny users="*" />
</authorization>
-->
</system.web>
<system.webServer>
<handlers>
<add name="ELMAH" verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />
</handlers>
</system.webServer>
I don't know why it does that, but it's not an error as far as I know. It does that on my site and Elmah continues to work just fine.
