iPads unfortunately do not authenticate with an active directory domain, full stop. That's the black and white of it. Yes I know, it sucks.
Incorrect....Lightspeed's bottle rocket device and licensing for iPads allows them to authenticate against an AD Domain as the Bottle Rocket pulls all of the AD users settings from the network and applies those to mobile devices Mobile Learning: Make education safe, mobile, collaborative
Obviously there are apps that support WebDAV, there are apps that support LDAP authentication but these are app specific, not iPad (as in the device itself) specific.
Incorrect...we resell a software solution that connects all of your AD users with WebDav, this in turn allows each user to log in to their home directories using their AD username/password and then upload documents, Photo's and videos, works exactly the same as if they were using a networked computer. Any apps that don't have webDAV support can use the "open in" function to copy the item to the App. Foldr - Remote File Access From Any Device & Workflow Solution For iOS
They also don't support multiple users. One user per device.
Need to set them up with Apples Configurator app which allows deployment of apps and settings as well as enabling restrictions. If you haven't looked at it yet you need to.
Additionally, purchase the apps via Apple's Volume Purchase Programme (VPP), get yourself enrolled.
Need to look at synchronisation as well, unless you want to manually set them up yourself. Griffin do some great cheap static towers, sync trollies get expensive.
There are apps out there that allow AD authentication but don't be fooled into believing that it can be used in any similar way to a windows device.
Still learning new things about them though, but my experience so far is to treat them as luxury additions to your IT equipment, not additions to your domain/network.
If you have any questions don't hesitate to message me, I've setup almost 100 iPads over the last couple weeks, at different schools, all with different intentions on how to use them, I've spoken to Apple, AT, Stone and other resellers. I certainly don't know everything but I'll tell you the things they won't as obviously they all work to the "Apple is the future" religion.
Can save you a lot of headaches, but won't promise to completely save you from them, sleepless nights are also another side effect of those glass/aluminium shiny toys.
