This is one of those questions that I've seen asked a lot but for some reason I've never really seen anyone post an answer to it. I did a quick Bing search before writing this post but didn't really see anything up there so I'm going to go out on a bit of a limb…

Updating Trust Between OnPrem Farms and ACS for Apps When Your SharePoint STS Token Signing Certificate Expires
For those of you who are "in the app way" with SharePoint 2013 (no, not a lot different from being "in the pregnant way", as they say), you'll reach that point sooner or later where the token signing certificate for your SharePoint STS expires if you are using low trust apps on premises. Why is…
Claim Type Exceptions with Custom Claims Providers in SharePoint 2013
This issue applies to SharePoint 2010 as well but…suppose you have created a custom claims provider and one of the things you want to do is to have some custom claim types that you use. What I mean by custom claim types is just that they are not one of the standard out of the…
More Info on an Old Friend – the Custom Claims Provider, Uri Parameters and EntityTypes in SharePoint 2013
Back to oldie but a goodie – the custom claims provider for SharePoint. I believe this applies to SharePoint 2010 as well but honestly I have only tested what I'm about to describe on SharePoint 2013 and don't have the bandwidth to go back and do a 2010 test as well. What I wanted to…
Enhancing the Yammer Search Results and Messages Samples and Deserialization
Just as kind of strange coincidence, I was in working on some Yammer message JSON goo and realized that there were actually a couple of other important data elements that comes down in the JSON payload when you get a collection of messages from REST. That includes both querying for messages directly, as well as…
Integrating Yammer and SharePoint 2013 Search Results
This post is in response to a question I get pretty frequently when talking about Yammer. The question that many folks want to know is "how can I crawl my Yammer content from SharePoint?" Well, unfortunately you can't, and I have no trick up my sleeve to show you otherwise today to say otherwise. However,…
Programmatically Adding A Trusted Identity Token Issuer to a Web Application Zone in SharePoint 2010 and 2013
Seems like I haven't had a chance to write a good SharePoint / SAML claims kind of article in a while. I was happily plugging away on some code this weekend for a scenario I haven't done before so I thought I would go ahead and post it here for the search engines. The whole…
Using Impersonation with the Yammer APIs
One of the things that isn't particularly well known about the Yammer APIs is that its OAuth infrastructure does support a form of impersonation (at least that's how I describe it). This can be extraordinarily useful when you need to access data on behalf of another user and do so within the constraints of the…
Some More Advice When Using the Yammer APIs with .NET
I wrote this post a little while back here: http://blogs.technet.com/b/speschka/archive/2013/10/05/using-the-yammer-api-in-a-net-client-application.aspx, and I think I'm going to have to fall on the sword just a bit because I have some code in there that I think has people kind of turned sideways. I wanted to briefly cover the concept of access tokens, and how you should get…
Update to Guidance for Patching AppFabric on SharePoint 2013 Distributed Cache Servers
For those of you who had the "pleasure" (okay, slight sarcasm there) of watching me in the SharePoint Ignite materials talk about distributed cache, you may recall that our guidance at the time SharePoint 2013 shipped was that you should not patch AppFabric on SharePoint servers independently – meaning that if it needed patching the…
