SharePoint serendipity is the effect by which one accidentally discovers something fortunate, especially while looking for something else entirely. In this case, it is the occassional musings, observations, and Ouija board readings about the phabulously

OAuth, o365 APIs and Azure Service Management APIs – Using Them All Together
I’ve been spending some time lately fooling around the o365 API’s. Frankly, it has been a hugely frustrating experience; I’ve never seen so many documentation gaps and examples and sample code that didn’t work, to flat out wouldn’t compile in a long time. So, once I finally...

Another Apps for SharePoint Tip with the Error "The issuer of the token is not a trusted issuer"
I was working on a build of SharePoint that is post beta 2 today, and found that one of my custom high trust apps I had built would no longer work. In looking at the ULS logs I was getting the dreaded "The issuer of the token is not a trusted issuer" error message. I think this is the equivalent of ...

Using SharePoint Apps with SAML and FBA Sites in SharePoint 2013
Hopefully by now everyone has heard about the new app model in SharePoint 2013. There’s a lot of documentation out there about it so I won’t go into exactly what it is. What you should know is that it’s the preferred model for developing applications going forward. If you’ve done...

How To Control App Token Lifetimes in SharePoint 2013
Today's post is the first selection from the little twitter contest I announced on the Share-n-Dipity blog a few days ago: http://blogs.technet.com/b/speschka/archive/2013/09/04/use-social-tools-to-tell-me-what-you-want-to-see-here-next.aspx . Shariq wanted to know more about the lifetime for high trust...

Missing Context Token in Low Trust App with SharePoint 2013
Should you decide that you want to write low trust apps for an on-premises SharePoint 2013 farm, there are a number of hoops you should expect to jump through (NOTE: this assumes the SPNs for your web apps are already configured in the MsolServicePrincipal for your o365 tenant): Create a new app...

Finally A USEFUL Way to Federate With Windows Live and SharePoint 2010 Using OAuth and SAML
Lots of folks have talked to me in the past about federating SharePoint with Windows Live. On the surface it seems like a pretty good idea – Windows Live has millions of users, everyone logs in with their email address, which is something we use a lot as an identity claim, it’s a big scalable...

Setting Up an oAuth Trust Between Farms in SharePoint 2013
One of the things you’re likely to hear a lot about in SharePoint 2013, and I may end up writing a lot about, is oAuth. In SharePoint 2013 oAuth is used to establish a trust between two applications for purposes of establishing the identity of a principal (user or application). In SharePoint you...

More TroubleShooting Tips for High Trust Apps on SharePoint 2013
Hey, I'm an app guy, I like doing dev, but honestly - I may go hoarse screaming at my computer if I have to track down one more "The issuer of the token is not a trusted issuer" problem with my new SharePoint apps. To try and help you save your own voice (and sanity) I'm going to start a list here of...

Facebook DataView WebPart Code from SharePoint Conference
For those of you who attended my SPC 351 session at SharePoint Conference today (Hitting the Ground Running with Claims Authentication), there was a request for some source code. As promised, I'm attaching a zip file with the source to the Facebook DataView WebPart I demonstrated. It's based on using...

OAuth and the Rehydrated User in SharePoint 2013 – How’d They do That and What do I Need to Know
First let me say that one of the things I like about blogging about random SharePoint mystery meat is the fact that I can use completely colloquial language like my blog title. Something that’s nearly impossible to get away with, unless, say, you are creating a new version of SharePoint. Anyone...
