you can't map to a domain account for the initial connection to tssa. you have to map to a local account so the os can be identified as windows. after that, you can use an 'Automation Principal', which can be a domain account, to communicate w/ the agent.
So we can't use domain account for initial connection .Is this a limitation in TSSA?
Customer has some security policies to not to use local account for any purpose. They are requesting to use only domain account.
for the initial connection during registration, you must connect w/ a local account so we can identify it as windows. after that you can use an ap (domain acct)
