Bug Alert for April CU and Migrating Users
Just heard about a nasty little bug in the April CU from my friend Syed. He was using the SPWebApplication.MigrateUsers method to migrate accounts from one claim value to another (i.e. like if you were migrating from Windows claims to SAML claims, or in his case, changing identity claim values). Turns...

Today's topic is one for which I deserve zero credit, I'm just putting out info that one of our crack engineers, Chad Ray, managed to dig up. I wanted to publish it here because I've worked with and talked to so many folks in the past who have struggled with getting a truly complete signout...

Desktop SharePoint Apps for SAML Secured SharePoint Sites

An Updated ClaimsTokenHelper for SharePoint 2013 High Trust Apps and SAML
When Visual Studio 2013 came out, it introduced a new class and simplified methods for obtaining a ClientContext to use with the Client Side Object Model (CSOM) to access SharePoint 2013 sites. A new SharePointContext class was added to simplify the programming model, but internally it still called the...

You Start Getting a 401 Unauthorized Error When Using the SharePoint Hybrid Features After Applying April 2014 CU or Later
This sounds scarily like a KB article, which I don't do, so we'll just jump straight to the facts. I noticed that after I applied the April 2014 CU to my farm that hybrid inbound search no longer worked. I subsequently confirmed with some other folks that they were seeing the same issue as well...

Access Denied Error with App Only Access Token When Reading Profile Info
This is yet another rather strange error that I ran across and couldn't find any info out on the interwebs about it so I though I would document it here.

Remote SharePoint Index, Hybrid, and SAML
Today's post combines a few different topics, that dare I say, started as a dare (I think).
