ADFS : ADFS 3.0 and OAuth2

This is for Server 2012 R2.

There are a lot of blogs about this but very little useful information.

So I thought about creating a client that shows this.

And then I thought about Authorization Server.

You can get this working if you want - just hook up to AS to ADFS as a normal ASP.NET RP for authentication.

But that's not what this post is about - I wanted to use the sample code to access ADFS.

Under "samples/Flows/Clients/OAuth2 CodeFlow you'll find the sample.

First you have to configure ADFS and you have to use PowerShell to do this - there's no wizard support.

You use the AdfsClient commands as per AD FS Cmdlets in Windows PowerShell.

Vittorio has blogged on this: Securing a Web API with Windows Server 2012 R2 ADFS and Katana.

Of interest is setting up the RP (worth repeating that it is neither WS-Fed nor SAML so don't tick any boxes) and the Add-AdfsClient command.  

My RP then looks like:

So running Get-AdfsClient on my box:

RedirectUri : {https://xxx/CodeFlow/callback}
Name        : AMCodeFlowClient
Description : AM Code Flow Client
ClientId    : codeclient
BuiltIn     : False
Enabled     : True
ClientType  : Public 

ToDo: Code changes to the sample.

Enjoy!

 

DOS : long file names

There are times when long file names are a pain.

I had a batch file that called a file inside a directory and the directory had spaces in the name e.g.

c:\a long name\another long name\program.exe

And it wouldn't damn well find it. Kept getting error messages like "File x ...".

I used "" and everything else I could think of.

Then from a long-distant past, I remembered DOS and the command

dir /x

This displays the short names generated for non-8dot3 file names.

So e.g. C:\Program Files\Resource Kit becomes C:\PROGRA~1\RESOUR~1

Putting the short name in the batch file solved the problem.

Go figure.

Visual Studio : Missing dll

So there I am - back to work in 2015 and rebuilding a MVC project which I haven't touched for a while and bang - error after error after ...

WTF - Happy New Year!

A long conversation with Mr. Google and:

Errors like:

Could not load file or assembly 'file:///C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Web Tools\Publish\Microsoft.VisualStudio.Web.Publish.dll' or one of its dependencies. The system cannot find the file specified.

and

Could not load file or assembly 'file:///C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Web Tools\Scaffolding\Microsoft.AspNet.Scaffolding.VSExtension.12.0.dll' or one of its dependencies. The system cannot find the file specified.

and

Could not load file or assembly 'file:///C:\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\Extensions\Microsoft\Web Tools\Languages\Microsoft.VisualStudio.JavaScript.Web.Extensions.dll' or one of its dependencies. The system cannot find the file specified.

etc.

This is related to VS 2013 Update 4 with ancillary suspects the Azure SDK 2.5 and O365 API Tools.

The solution is to repair VS 2013 Update 4.

I have Windows 7 so:

Control Panel - Programs and Features - Installed Updates - Visual Studio 2013 Update 4 (KB2829760) - Repair.

Just take a looong break while it's running.

Enjoy!
