How to join the Politecnico Active Directory

Joining your machine to the Politecnico Active Directory authentication infrastructure allows you to authenticate on your machine with your institutional credentials (, and be able to configure easily many network services, e.g. network printers and file shares.

Provided that you requested to join the AD domain when submitting the ip address request form, you will be able to join on your own your device to the '' authentication domain, authenticating with your institutional credentials. Note that joining a domain (on your own or assisted) is supported by the DET IT team only for Windows operating systems.
