iPhone using WPA Enterprise with RB751 and MT User Manager

Hi,
I setup the Mikrotik hotspot solution together with the Mikrotik User Manager but would rather use WPA Enterprise instead.

Is there a HOWTO available, that shows how to use an iPhone with username/password (EAP-TLS ?) to logon to a RB751 that uses the Mikrotik User Manager for managing the users/passwords?

Thanks,
