A new version 4.7 of Userbooster for iPhone and iPad has just been released and available in App Store https://itunes.apple.com/en/app/userbooster/id587122342?mt=8&ign-mpt=uo%3D2 and https://itunes.apple.com/us/app/userbooster-for-ipad/id647681854?l=de&ls=1&mt=8.
Unlike similar tools for managing directory servers, Userbooster allows you to create, modify and delete objects locally and then commit the changes to a directory server in a mouse click. And you can do this from your Windows desktop, iPhone and iPad. All three products have the same configuration file so you can synchronize the settings between your devices via http/https or email.
You can learn more about the products on the Userbooster website at http://userbooster.de/products/userbooster-for-iphone.aspx and http://userbooster.de/products/userbooster-for-ipad.aspx.
