Spring Security Active Directory LDAP Authentication without full name

Question

Using Spring Security 3.2 I have configured ActiveDirectoryLdapAuthenticationProvider. I am able to authenticate using full name example [email protected] but when I try to authenticate with just username 'sharon' I get the below error

   2015-12-21_17:07:00.752 DEBUG o.s.s.l.a.a.ActiveDirectoryLdapAuthenticationProvider - authenticate - Processing authentication request for user: sharon
    2015-12-21_17:07:00.793 DEBUG o.s.s.l.SpringSecurityLdapTemplate - searchForSingleEntryInternal - Searching for entry under DN '', base = 'dc=mydomain,dc=com', filter = '(&(objectClass=user)(userPrincipalName={0}))'

As per spring security document :

A user named "Sharon", for example, would then be able to authenticate by entering either the username sharon or the full Active Directory userPrincipalName, namely [email protected]

my configuration

@Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider());
        auth.eraseCredentials(false);
        auth.ldapAuthentication().userDnPatterns("cn={0},CN=Users,DC=mydomain,DC=com");
    }

    @Bean
    public ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
        ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(env.getProperty("mydomain.com"),
                env.getProperty("ldap://hmidir01.mydomain.com:389/"));
        provider.setConvertSubErrorCodesToExceptions(true);
        provider.setUseAuthenticationRequestCredentials(true);
        provider.setUserDetailsContextMapper(userDetailsContextMapper);
        return provider;
    }

What is the mistake in my configuration.

You can implement in given ways :

1) Without persisting data into our database

WebSecurityConfig .java

@Configuration
@EnableWebMvcSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter  {

    @Bean
    public ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
        ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(<ldap-domain>,<ldap-url>);
            provider.setConvertSubErrorCodesToExceptions(true);
            provider.setUseAuthenticationRequestCredentials(true);
        return provider;
    }

    @Bean
    public LoggerListener loggerListener() {
        return new LoggerListener();
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
        .authorizeRequests()
            .antMatchers("/admin/**").hasAnyAuthority("ADMIN")
            .antMatchers("/user/**").hasAnyAuthority("ADMIN", "USER")
            .antMatchers("/rest/**", "/css/**", "/fonts/**", "/images/**", "/js/**").permitAll()
            .anyRequest().authenticated()
        .and()
            .formLogin()
            .loginPage("/").failureUrl("/?error").successHandler("/home").permitAll()
            .usernameParameter("emailId").passwordParameter("password")
        .and()
            .logout()
            .logoutUrl("/logout").logoutSuccessUrl("/").permitAll()
        .and()
            .exceptionHandling().accessDeniedPage("/home")
        .and()
            .csrf()
        .and()
            .httpBasic();    
    }
}

2) With persisting data into our database

WebSecurityConfig.java

@Configuration

            .antMatchers("/user/**").hasAnyAuthority("ADMIN", "USER")
            .antMatchers("/rest/**", "/css/**", "/fonts/**", "/images/**", "/js/**").permitAll()
            .anyRequest().authenticated()
        .and()
            .formLogin()
            .loginPage("/").failureUrl("/?error").successHandler("/home").permitAll()
            .usernameParameter("emailId").passwordParameter("password")
        .and()
            .logout()
            .logoutUrl("/logout").logoutSuccessUrl("/").permitAll()
        .and()
            .exceptionHandling().accessDeniedPage("/home")
        .and()
            .csrf()
        .and()
            .httpBasic();
    }

        return provider;
    }

    @Bean
