This is also an option that may be enabled on the device, and is used in conjunction with scan to network
and scan to email features. 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.
2) The Domain Controller responds back to the device through the router whether or not the user
was successfully authenticated.
If (2) is successful, steps 3 – 5 proceed as described in 4 - 6 of Kerberos section.
