OK so it addresses DCs to check some settings or priviliges. I don't 
suppose it just asks 'hey DS, can contoso\johnd access sshd on server1?' 
to which the DC is like 'dude, what the heck is sshd?' :) I now have the 
cygwin service running in domain context so now I would somehow need to 
let the DC know whe is allowed to ssh to my server1. My domain account, 
although in local admins on the server is now failing authentication 
when trying to ssh. Which gets us back to the question what do I need 
for a DC to authenticate me?

Maybe a bug then?

Yeah, sorry for my bad formatting. Working on that. Hope I'm not 
top-posting again.
