Not prompted for password on Cisco UC520 via SSH

I have a UC520,  I've created users on it via CLI, set the Enabled/Secret passwords etc.. yet when I SSH in I can literally just type in any username for any user that exists on the system and it logs me right in to #.  It doesn't even prompt for a password.   This is obviously a huge security risk and being a bit hesitant to post my config and leave some identifying information in it I'm hoping that someone could point me in a direction.

So if I lower the privilege to say 1 from its current 15 users will be prompted with a password to access privileged commands?

Even with a high privilege shouldn't the user be prompted for their password though?
Login Authentication Using Enable Password

Use the aaa authentication login command with the enable method keyword to specify the enable password as the login authentication method. For example, to specify the enable password as the method of user authentication at login when no other method list has been defined, enter the following command:

aaa authentication login default enable

Before you can use the enable password as the login authentication method, you need to define the enable password. For more information about defining enable passwords, refer to the chapter "Configuring Passwords and Privileges."

The solution was changing the aaa authentication default to enable, it was currently set to none.  Thanks!
