How to stop ANONYMOUS LOGON ?
I have SSO filter working perfectly fine , but when a non-domain user is presented with Basic authentication pop-up , and if user simply presses "Sign in" button on Chrome (i.e. with empty credentials) , Waffle allows this as  authenticated user

waffle.servlet.NegotiateSecurityFilter - previously authenticated Windows user: NT AUTHORITY\ANONYMOUS LOGON]

How do I stop this ? And it's only happening with Google Chrome ! MS Edge surprisingly doesn't go ahead with blank credentials, but Chrome does !

Here are some other details :

AppServer - Glassfish 4

Browser - Google chrome

Waffle SSO type - Filter based (version 2.3.0)

OS : Windows 10

My mistake ! I wasn't aware about guestLogin being on by default . 

Doing this , solved it :

<filter>

    <filter-name>SecurityFilter</filter-name>

    <filter-class>waffle.servlet.NegotiateSecurityFilter</filter-class>

    <init-param>

        <param-name>allowGuestLogin</param-name>

<param-value>false</param-value>

    </init-param>

</filter>
