AutoLogin in Answer File

Question

I am trying to get passed the creation of the account with an answer file when loading an image on another machine.

I have:

<component name="Microsoft-Windows-Shell-Setup" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <AutoLogon>
                <Password>
                    <Value>xxx</Value>
                    <PlainText>false</PlainText>
                </Password>
                <Enabled>true</Enabled>
                <LogonCount>5</LogonCount>
                <Username>AdminUser</Username>
            </AutoLogon>

AdminUser is the admin account I created when I did the configuration of the reference machine. I would like the setup to us this account instead of having to create a new one during the setup process.

Is this possible? What am I missing? What are the requirements for autologin and having the answer file tell the setup to not ask for a user name a password during installation?
