I've got a new corporate laptop and started running into this problem that I've never seen before. I am using AWS Session Manager plugin to connect to an AWS EC2 Windows instance, although none of that is relevant. The problem is that my username is being updated after I try to connect.
For example, I'll log in as "Administrator" but once I connect and it queries me for the password, it then fails and shows that I am logging in as "Administrator@xyz.com" Since this is an AWS instance, it won't accept the username with my domain appended onto it. How do I stop this?
