7.6 no (except when the agent is on a domain controller because there are no local accounts). I believe this is coming in 8.x.
you can do it with 8.0 using this thing called an Automation Principal
do you have any additional information on that topic.
We are implementing 8.0 right now.
What especially is meant with "Automation Principal"
automation principal (look in the admin pdf) will let you map a role to 1 domain user. we do not do 1 to 1 mapping of blade users to ad users yet.
