I've had a request from the boss :(
I've had a look around my usual places of knowledge seeking but haven't come up with an answer.

Does anyone know if it is possible to force AD passwords on Blackberries?
I know how to set and force passwords through BES but as most of our users have trouble remembering their own name remembering another password is going to be difficult!

Any help or pointers greatfully received.

BlackBerry device passwords cannot be synchronised with AD.

That's just the answer I was looking for, thanks.
