How to get Spring Boot and OAuth2 example to use password grant credentials other than the default

As I'm still on 2.0.3, I tried a few more things and this appears to be working:

@Configuration@EnableWebSecurity@EnableGlobalMethodSecurity(prePostEnabled = true)protected static class WebSecurityConfig extends WebSecurityConfigurerAdapter {    @Override    protected void configure(AuthenticationManagerBuilder authManagerBuilder) throws Exception {        authManagerBuilder            .inMemoryAuthentication()                .withUser("user1").password("password1").roles("USER").and()                .withUser("admin1").password("password1").roles("ADMIN");    }    @Bean    @Override    public AuthenticationManager authenticationManager() throws Exception {        return super.authenticationManager();    }}

By explicitly defining the authenticationManager bean, the built-in user authentication went away and it started relying on my own inMemoryAuthentication. When 2.0.4 is released, I'll re-evaluate the solution that Dave posted above as it looks like it will be more elegant.

@Configurationprotected static class AuthenticationManagerConfiguration extends GlobalAuthenticationConfigurerAdapter {        @Override        public void init(AuthenticationManagerBuilder auth) throws Exception {            auth.inMemoryAuthentication().withUser("min").password("min").roles("USER");        }    }
