Default Security Principal & Role Mapping

[Aaron Mulder]

If I have a security configuration block like this, is an
unauthenticated user given the Admin role?  Or does role mapping
ignore the default principal?

Thanks,
    Aaron

<security>
  <default-principal>
    <principal class="..." name="bob" />
  </default-principal>
  <role-mappings>
    <role name="Admin">
      <principal class="..." name="bob" />
    </role>
  </role-mappings>
</security>
