Unable to find the ssh user to ssh in.
the install of the AMI was smooth, and the odoo application was able to be installed.
However, when I tried to ssh to the server, I found that the regular ids ( ubuntu, root, ec2-user, etc ) don't work. i also tried to guess about some users like openerp and odoo, but no luck there too.
This is not documented, and has led to many hours of frustration.
