I get the error "{"The remote server returned an error: (403) Forbidden."} The HTTP request was forbidden with client authentication scheme 'Anonymous'." when using basicHttpBinding with Transport security and certificate credential. My service is in amazon ec2 instance and my client app remotely connect to it over the internet. I am able to connect to the wcf service if my Transport credential is set to "None" in both the web.config of the service and app.config of the client. My service certificate is like "www.example.com" is installed on amazon ec2 "local machine store" and "Personal Folder". My client app certificate is just a self-signed certificate which I installed to its "local machine and Personal Folder" and also to the "Trusted People store" in the amazon ec2 instance where my wcf service is. I have also setup "https" to my IIS site bindings and I can reach the site through like "https://www.example.com"

Below is the web.config, app.config, and the code I have on the client app.

I did look to other similar issues but none has solve it yet, I'm continuously searching for the right solutions, I appreciate any help or advice the community provides.

EDIT:

Probably better to use a sha2 cert:

makecert -len 2048 -r -a sha256 -sv private.pvk -n CN=yoursubjectname cert.cer

pvk2pfx -spc cert.cer -pvk private.pvk -pfx out.pfx

Install the private cert(.pfx) on the host, set in IIS app, and install the public cert on the client(.cer), you will have to install in both personal and trusted people stores.

EDIT: I think you also need to give your behavior a name in the host and client config and assign that behavior to your endpoints.

Host:

<behavior name="serviceBahavior"> 

<service name="MyProject.MyService" behaviorConfiguration="serviceBahavior">

Client:

<behavior name="clientBahavior">

<endpoint address="https://www.example.com/sub/Service1.svc"

          binding="basicHttpBinding" bindingConfiguration="basicHttpBinding_Config"

          contract="ServiceReference1.MyService" name="BasicHttpBinding_MyService" behaviorConfiguration="clientBahavior" />

I think since you are using <security mode="Transport"> you will need to make your mex as HTTPS:

 <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />

Also set in your behavior the serviceMetadata

from:
<serviceMetadata httpGetEnabled="true"/>

to <serviceMetadata httpsGetEnabled="true"/>

Also, make sure your transport in the client config matches the host config:

<transport clientCredentialType="Certificate"/>

I found the following solution that works for this error I encountered.

First, I created a certificate as follows:

makecert -n "CN=MyRootSigningKey" -r -sv MyRootSigningKey.pvk MyRootSigningKey.cer

Second, I treat this as my root key and install it in my AWS service under the certificate store "Trusted Root Certification Authorities" using mmc.

Third, I created a self-signed cert using the root key "MyRootSigningKey" as follows:

makecert -sk MySignedKeyName -iv MyRootSigningKey.pvk -n "CN=MySignedKey" -ic MyRootSigningKey.cer -sr localmachine -ss my -sky exchange -pe

Last, I reference the self signed cert "MySignedKey" in my client app config like below:

<client>        

        <endpoint address="https://www.example.com/sub/Service1.svc" behaviorConfiguration="clientBehavior"

          binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_MyService"

          contract="ServiceReference1.MyService"  />



      </client>
