o.s.s.o.provider.endpoint.TokenEndpoint : Handling error: InvalidGrantException, Bad credentials

Question

I am developing Spring Cloud authorization server, I am not getting any error when I start the server, but when I tried to access the http://localhost:9000/services/oauth/token, I get the below error.

Could you please guide what the issue is ? I wonder why its saying invalid grant though grant_type is correct ?

PluralsightSpringcloudM4SecureauthserverApplication

@SpringBootApplication
@EnableAuthorizationServer
@EnableResourceServer
@RestController
public class PluralsightSpringcloudM4SecureauthserverApplication {

    public static void main(String[] args) {
        SpringApplication.run(PluralsightSpringcloudM4SecureauthserverApplication.class, args);
    }

    @RequestMapping("/user")
    public Principal user(Principal user) {
        return user;
    }
}

ServiceConfig

@Configuration
public class ServiceConfig extends GlobalAuthenticationConfigurerAdapter {

    @Override
    public void init(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
        .withUser("agoldberg").password("pass1").roles("USER").and()
        .withUser("bgoldberg").password("pass2").roles("USER", "OPERATOR");
    }
}

Answer 1

I had a similar issue and it was solved by defining an identifier for the password storage format.

.withUser("agoldberg").password("{noop}pass1")

More info in the following link password storage format
