In my last tumblr session I came along a post about Barry Underwood’s pictures. He’s a photographer with a talent for amazing light painted photos.
The pictures you’re seeing haven’t been edited in Photoshop or any other software. Barry Underwood took this photographs with a long exposure camera installation and a bunch of lights.
Since SharePoint 2013 only supports claim based authentication I discovered that updates in SharePoint Active Directory groups do not take effect immediately.
Thanks to Ryan McIntyre there’s a simple fix for that issue.
By adjusting the lifetime of the claims token you can shorten the time it takes to update the Active Directory group changes.
