I've been working recently with some Microsoft Services and their customers who are changing the SharePoint STS token signing certificate. We are doing this as part of the set of steps required to set up the SharePoint Hybrid features for integrating search and BCS between on premises SharePoint farms and Office 365. I've had a…

400 Bad Request Error with ADFS
I spent waaayyyyy too much time trying to resolve this problem so am capturing it here in case any of the rest of you run up against this. I installed a new ADFS 3.0 on Windows Server 2012 R2 machine in my environment, and then configured a new SharePoint SPTrustedIdentityTokenIssuer for it. Every time I…
Uploading File Attachments to Yammer
Working with attachments to message postings in Yammer has been something that I've had a few questions on over time and just recently had a chance to take a look at it. I decided to blog about it only because there appears to be such paucity of information around folks that have actually done this…
Remote SharePoint Index, Hybrid, and SAML
Today's post combines a few different topics, that dare I say, started as a dare (I think). The gauntlet thrown out was whether or not Remote SharePoint Index would work for SAML users as well as Windows users. For those of you not completely familiar with Remote SharePoint Index, I covered it in some detail in my blog…
SAML in a Box – Inviting External Users to Your SharePoint Farm
Those of you who follow the Share-n-Dipity blog know that I don’t really do much in the way of product endorsements. However, you have probably also figured out that I’m a big SAML fan, so when a friend of mine recently released a new product for this market it really caught my eye. If you’ve…
Using Yammer Open Graph in .NET – Part 2
In the first part of this series – http://blogs.technet.com/b/speschka/archive/2014/05/29/using-yammer-open-graph-in-net.aspx – I described how to create a Yammer Open Graph object (OGO). In this posting I'll explain how to create a new post in the newsfeed for the OGO, as well as read all messages that have been posted to that OGO. Just like the previous…
Using Yammer Open Graph in .NET – Part 1
I've already written about using the Yammer APIs from a .NET client application here: http://blogs.technet.com/b/speschka/archive/2013/10/05/using-the-yammer-api-in-a-net-client-application.aspx. This post is the next logical step in that journey, which is working with Yammer Open Graph items from .NET. A little background is probably in order though, like what is this Yammer Open Graph thing and how or why…
SAML Support for SharePoint-Hosted Apps with ADFS 3.0
This is another case where I'm just passing information along here, based on the great work of others. As you probably know, we did not have a good story for SharePoint-hosted apps in web application that uses SAML authentication with ADFS 2.0. However, I have had reports from a couple of different teams now that…
Changes To Know About When Your SharePoint STS Token Signing Certificate Expires – the Impact to Your High Trust Applications
This is a another follow up to my earlier post on changing the token signing certificate for the SharePoint STS as described here: http://blogs.technet.com/b/speschka/archive/2014/05/06/updating-trust-between-onprem-farms-and-acs-for-apps-when-your-sharepoint-sts-token-signing-certificate-expires.aspx. As I mentioned in that post, you will undoubtedly wind up in this situation if you configure your farm to use low trust apps, because as part of creating the trust…
Missing Context Token in Low Trust App with SharePoint 2013 – Part 2
As I noted in my first post on this topic – http://blogs.technet.com/b/speschka/archive/2013/05/28/missing-context-token-in-low-trust-app-with-sharepoint-2013.aspx – you may find yourself in a low trust app without a context token, which basically leaves you up the creek without a paddle. I ran across another scenario where this was happening so thought I would add it to my list of app…
