The org.myapp.openid.service.CustomUserDetailsService.java

        String id = token.getIdentityUrl();
        CustomUserDetails user = registeredUsers.get(id);

        if (user != null) {
            return user;
        }

        String email = null;
        String firstName = null;
        String lastName = null;
        String fullName = null;

        List attributes = token.getAttributes();

        for (OpenIDAttribute attribute : attributes) {
            if (attribute.getName().equals("email")) {
                email = attribute.getValues().get(0);
            }

            if (attribute.getName().equals("firstname")) {
                firstName = attribute.getValues().get(0);
            }

            if (attribute.getName().equals("lastname")) {
                lastName = attribute.getValues().get(0);
            }

            if (attribute.getName().equals("fullname")) {
                fullName = attribute.getValues().get(0);
            }
        }

        if (fullName == null) {
            StringBuilder fullNameBldr = new StringBuilder();

            if (firstName != null) {
                fullNameBldr.append(firstName);
            }

            if (lastName != null) {
                fullNameBldr.append(" ").append(lastName);
            }
            fullName = fullNameBldr.toString();
        }
        ....
    }
}

when i am debugging, method loadUserByUsername(), there is a Url returned, but the OpenIDAttributes are null (email,firstname and lastname).
I think I must configured the spring-security.xml wrong, please help. Thanks

A: Just make attributes requierd:
`<beans:bean class="org.springframework.security.openid.OpenIDAttribute">
                    <beans:constructor-arg index="0" value="email" />
                    <beans:constructor-arg index="1" value="http://schema.openid.net/contact/email" />
                    <beans:property name="required" value="true"/>
</beans:bean>`
