Question

I have a custom role provider that inherits off RoleProvider. In the web app this works fine with no problems.

However I am also using it in the WCF service and am having great problems stepping into it. to the extent that I suspect it isn’t being hit at all. If I turn on any principal permissions at all I get access denied and the stack trace is totally unhelpful. even the WCF traces arnt really helpful in ascertaining what has happened.

I know that the TennisRoleProvider works off its default constructor and have verified its methods via test. It seems to be an integration issue.

So snippets …

EDIT: I have since moved the role provider into the service assembly as read something about needing to involve GAK and keys (needs to run in full trust). I went down that path but things still didnt work so decided to simply move stuff into the service project to simplify. Still no joy.

<roleManager defaultProvider="TennisRoleProvider"
             enabled="true"
             >
  <providers>
    <clear/>
    <add name="TennisRoleProvider"
         type="Tennis.Security.TennisRoleProvider, Tennis.Security" />
  </providers>
</roleManager>

   <bindings>
     <wsHttpBinding>
        <binding name="wsHttpUserName">
          <security mode="TransportWithMessageCredential">
            <message clientCredentialType="UserName"/>
            <transport clientCredentialType="None"/>
          </security>
        </binding>
     </wsHttpBinding>
   <bindings/>


    <behavior name="RoleBehavior">
       <serviceCredentials>
         <serviceCertificate findValue="john-pc"
                      storeLocation="LocalMachine"
                      storeName="My"
                      x509FindType="FindBySubjectName"/>
       <userNameAuthentication userNamePasswordValidationMode="Custom" 
customUserNamePasswordValidatorType="Tennis.Components.TennisUserValidator, Tennis.Components"/>
      </serviceCredentials>

      <serviceAuthorization principalPermissionMode="UseAspNetRoles" 
                            roleProviderName="TennisRoleProvider">
      </serviceAuthorization>

      <serviceMetadata httpsGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
      <errorHandler />
    </behavior>

   <services>
      <service name="Tennis.Service.Services"
               behaviorConfiguration="RoleBehavior">
          <endpoint address="Family"
                 binding="wsHttpBinding"
                 bindingConfiguration="wsHttpUserName"
                 contract="Tennis.Service.Contracts.IFamilyAdmin"
                  />
      </service>
    </services>

Then on the service method i have the following (Roles.Family admin is a string)

[PrincipalPermission(SecurityAction.Demand, Name = Roles.FamilyAdmin)]
public VoidResult<SuccessEnum> UpdateFamily(Family family)
{

}

so there are 2 questions …
1) what have I done wrong?
2) How can I get into WCF to figure out exactly what is going wrong?

Cheers

The stack trace for the error in the logs is as follows
Note the permission in there is a different to the one I used above (Namley ‘authorised’ instead of ‘FamilyAdmin’. However In the real thing those values match and the user has the correct permissions.

EDIT: Based on the answer below I added a few lines of code into the constructor – which whilst they don’t achieve anything encouraged me to interrogate the thread static class.

EDIT: given a question about logs updated log to show that it is indeed from the log – or I am confused 😉

The TennisRoleProvider is referenced by it in its non public members – moreover when I overrode Name to make it return something I would recognise this was returned by it.

Answer 1

The problem was that I am using security across assemblies / app domains.

I need to make everything trusted and signed for it to work.
