I try to configure user role firewall on MAG 2600 with MAGx600-UAC-SRX license. I am using the Windows Server 2008R2 and UAC 4.4. I want to setup SSO using SPENGO protocol. Can someone explain me the steps how to configure Active Directory? I want to know the exact steps I should perform on AD. How to setup "DNS" and "User and Computers" settings and use of "ktpass" command on AD?
