WCF configuration - Custom authentication on the host - wcf

Question

I've been struggling with this for a couple of days now - I cannot get this WCF service configured correctly to use a custom membership provider. When I fire up the test client I get this error:
The username/password Membership provider MidlandsCoop.MembersWcfService.Business.UserAuthentication specified in the configuration is invalid. No such provider was found registered under system.web/membership/providers.
I have been following this MSDN link to no avail. Can anyone tell me where I'm going wrong?
Here's my web.config:
<?xml version="1.0"?>
<configuration>
<connectionStrings>
<add name="MyCS" connectionString="Data Source=my server;Initial Catalog=MyDB;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>

<wsHttpBinding>

<endpoint binding="wsHttpBinding" bindingConfiguration="wsHttpBinding"
name="wsHttpBinding" contract="MidlandsCoop.MembersWcfService.IMembersService" />
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>

membershipProviderName="MidlandsCoop.MembersWcfService.Business.UserAuthentication" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
</configuration>
My user authentication class is as follows:
public class UserAuthentication : UserNamePasswordValidator
{
public override void Validate(string userName, string password)
{
if (null == userName || null == password)
{
throw new ArgumentNullException();
}
var db = new PetaPoco.Database("MyDB");
db.Fetch<dynamic>("SELECT Username, Password FROM MyTable WHERE Username=#0 AND Password =#1",
userName, password);
}
}
Any suggestions would be greatly appreciated.

Answer 1

the link that you have provided mentions customUserNamePasswordValidatorType to specify custom authentication type, UserAuthentication in your case. I think MembershipProviderName should be a class derived from MembershipProvider Class.
