Spring Security Basic Auth Prompt Appearing

Why would I get the basic auth prompt when I go to /preregistered/* ? I thought the below configuration would only make basic auth apply when /services/** url path was matched. I'm using spring-security 3.1.0.M1

Are you trying to reach an .xhtml under /preregistered ?

If you try to reach http://yoururl.com/preregistered/something.xhtml.

Your intercept-url definition:

<intercept-url
        pattern="/**/*.xhtml"
        access="ROLE_NONE_GETS_ACCESS" />

will intercept it.
