Assistance Needed with Azure AD OAuth2 Integration in Vaadin CRM Application

[RainioLO]

I am currently working on integrating Azure Active Directory (Azure AD) OAuth2 login functionality into a Vaadin CRM application I'm developing for practice, based on a tutorial setup. I have followed the instructions to register the application on the Azure portal and configured the application's settings accordingly.

Issue Description
Despite setting up everything as per the guidelines, I am encountering a persistent issue where the application fails to redirect to Azure for authentication. Instead, it redirects back to the local /login page. Here are the details of my current setup:

Registered App on Azure Portal
Redirect URI Configured: http://localhost:8090/login/oauth2/code/aad
Application.yml Configuration: I have configured the .yml file as per the Azure setup instructions.

@EnableWebSecurity
@configuration
public class SecurityConfig extends VaadinWebSecurity {

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeHttpRequests(auth ->
            auth.requestMatchers(
                    AntPathRequestMatcher.antMatcher(HttpMethod.GET, "/images/*.png")).permitAll());
    super.configure(http);
    setLoginView(http, LoginView.class); // link http and the LoginView
}

@Bean
public UserDetailsService users() {
    UserDetails user = User.builder()
            .username("user")
            .password("{bcrypt}$2a$10$GRLdNijSQMUvl/au9ofL.eDwmoohzzS7.rmNSJZ.0FxO/BTk76klW")
            .roles("USER")
            .build();
    UserDetails admin = User.builder()
            .username("admin")
            .password("{bcrypt}$2a$10$GRLdNijSQMUvl/au9ofL.eDwmoohzzS7.rmNSJZ.0FxO/BTk76klW")
            .roles("USER", "ADMIN")
            .build();
    return new InMemoryUserDetailsManager(user, admin);
}

}

Request
I would appreciate it if you could review my configuration or provide any insights into what might be causing this redirection issue. If there is a common pitfall or additional configuration step that I might be missing, your guidance would be highly valuable.

Thank you for your time and assistance.
