The authentication steps vary somewhat, depending on the network configuration. Listed below are 3 network
configurations and the authentication steps.
Basic Network Configuration: Device and Domain Controller are on the same
Subnet
Authentication Steps:
1) The device broadcasts an authentication request that is answered by the Domain Controller.
2) The Domain Controller responds back to the device whether or not the user was successfully
authenticated.
If (2) is successful, steps 3 – 5 proceed as described in steps 4 – 6 of the Kerberos section.
Device and Domain Controller are on different Subnets, SA defines IP Address of
Domain Controller
Authentication Steps:
1) The device sends an authentication request directly to the Domain Controller through the router using
the IP address of the Domain Controller.

successfully authenticated.
If (2) is successful, steps 3 – 5 proceed as described in 4 - 6 of Kerberos section.
