Azure Access Control - ACS50000: There was an error issuing a token.

 

I have been playing with the Azure Access control solution and how to put an application into the Azure Marketplace SaaS offering. The first issue I ran into was getting ACS to work. I had developed a solution with Microsoft’s Active Directory Federation services 2.0 before some the concept was familiar to me. Even through the topic was familiar to me federation errors are often still a pain to resolve.

The first thing you have to do is understand if the error is coming from the provider or client. In this case even though ACS is throwing the error the error is actually coming from the client as it is rejecting the token. It can be rejecting the token for a few reasons.

1) The certificate thumbprint the website is looking to validate against does not match. Check the sites web.config trusted issuers section and make sure the thumbprint matches what ACS has.

 <issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
    <trustedIssuers>
        <add thumbprint="[yourthumbprint]" name="[yournamespace]" />
    </trustedIssuers>
</issuerNameRegistry>

Here is where you get the thumbprint from in the Azure ACS

If that does not work your wreply URL back to your website is not correct.

2) Check that the URL the token is being issued for (based on the wreply url) matches the audience URI configured in your application.

In my case I was in my development environment and therefore using odd port numbers. Once I updated the return URL so it had the port number of 444 and the audience URI in my web config to match it worked.

MVVM light and Model Validation

I have been using the MVVM light toolkit for a project recently. It is a great toolkit but is missing a couple things and Laurent Bugnion does a good job trying to cover those holes. One of the things the toolkit does not support is Validation. The good news is there is a great CodePlex project out there call Fluent Validation that makes this pretty easy to add and really powerful. My objective was to add validation to my model so I could call “IsValid” on the model itself (similar to the MVC attribute approach). Fluent Validation has you create a new class file that holds you validation rules for a given model. This is the approach I took to enable each model to have an “IsValid” property and a “Errors” property that returns the validation errors.First I setup my ValidationFactory:publicclass ValidatorFactory : FluentValidation.ValidatorFactoryBase{publicoverride FluentValidation.IValidator CreateInstance(Type validatorType) {return SimpleIoc.Default.GetInstance(validatorType) as …

Experience Profile Anonymous, Unknown and Known contacts

When you first get started with Sitecore's experience profile the reporting for contacts can cause a little confusion. There are 3 terms that are thrown around, 1) Anonymous 2) Unknown 3) Known. When you read the docs they can bleed into each other a little.

First, have a read through the Sitecore tracking documentation to get a feel for what Sitecore is trying to do.

There are a couple key things here to first understand:

Unless you call "IdentifyAs()" for request the contact is always anonymous. Tracking of anonymous contacts is off by default. Even if you call "IdentifyAs()" if you don't set facet values for the contact (like first name and email) the contact will still show up in your experience profile as "unknown" (because it has no facet data to display).  Enabled Anonymous contacts


Notice in the picture I have two contacts marked in a red box. Those are my "known" contacts that I called "IdentifyAs" on. I know they say &…

Excel XIRR and C#

I have spend that last couple days trying to figure out how to run and Excel XIRR function in a C# application. This process has been more painful that I thought it would have been when started. To save others (or myself the pain in the future if I have to do it again) I thought I would right a post about this (as post about XIRR in C# have been hard to come by). Lets start with the easy part first. In order to make this call you need to use the Microsoft.Office.Interop.Excel dll. When you use this dll take note of what version of the dll you are using. If you are using a version less then 12 (at the time of this writing 12 was the highest version) you will not have an XIRR function call. This does not mean you cannot still do XIRR though. As of version 12 (a.k.a Office 2007) the XIRR function is a built in function to Excel. Prior version need an add-in to use this function. Even if you have version 12 of the interop though it does not mean you will be able to use the function. The a…

WPF Localization - RESX Option

About a year ago I was building a WPF project in .Net 3.0 and Visual Studio 2005. I wanted to revisit this subject and see what has changed in .Net 3.5 and Visual Studio 2008. I will make a few of these posts to try and cover all the different options (RESX option, LocBaml option, Resource Dictionary Option). In this blog I will focus on using a resx file to localize an application. To show how the resx option is done I created a WPF form with three labels on it. The first label has is text set inline in XAML, the second has it text set via code behind from the resx file and the third has its text set via XAML accessing the resx file. The first thing that needs to happen to setup a project for localization is a small change to the project file. To make this change you will need to open the project file in notepad (or some other generic editor). In the first PropertyGroup section you need to add the follow XML node <UICulture>en-US</UICulture>. So the project file node woul…

Uniting Testing Expression Predicate with Moq

I recently was setting up a repository in a project with an interface on all repositories that took a predicate. As part of this I needed to mock out this call so I could unit test my code. The vast majority of samples out there for mocking an expression predicate just is It.IsAny<> which is not very helpful as it does not test anything other then verify it got a predicate. What if you actually want to test that you got a certain predicate though? It is actually pretty easy to do but not very straight forward.Here is what you do for the It.IsAny<> approach in case someone is looking for that. this.bindingRepository.Setup(c => c.Get(It.IsAny<Expression<Func<UserBinding, bool>>>())) .Returns(new List<UserBinding>() { defaultBinding }.AsQueryable()); This example just says to always return a collection of UserBindings that contain “defaultBinding” (which is an object I setup previously). Here is what it looks like when you want to pass in an expressi…
