如何使用Spring Ldap身份验证

Question

In my current project, I have to implement LDAP authentication. I am using JSF 2.2, primefaces and Spring 4.0 and spring-ldap-core 1.3.2 and spring-security-ldap-3.2.0. Below are the work till now I have done to achieve:

Spring-Ldap.xml

<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
 <property name="url" value="ldap://mumcXXXXXXX" />
 <property name="base" value="dc=ad,dc=XXX,dc=com"/>
 <property name="userDn" value="XXXX@ad.XXX.com" />
 <property name="password" value="XXXX" />
 </bean>

 <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
    <constructor-arg ref="contextSource" />
</bean>

<bean id="ldapContact"
    class="com.csap.research.LDAPContactDAO">
    <property name="ldapTemplate" ref="ldapTemplate" />
</bean>

My LdapContactDao

public boolean login(String username, String password) {
        AndFilter filter = new AndFilter();
        ldapTemplate.setIgnorePartialResultException(true); 
        filter.and(new EqualsFilter("userPrincipalName", username+"@ad.cXXX.com"));
        return ldapTemplate.authenticate("", filter.toString(), password);
}

Here username and password are coming from Login screen as inputs. My problem is its very hardcoded. I dont want to hardcode username and password in Spring-Ldap.xml , So there was a suggestion to use Spring-security-Ldap here Spring LdapAuthentication and Load roles from local database but I was unable to understand it.

My question was how I can achieve dynamic integration of Ldap with spring and corse JSF i am using as a front-end controller. Any help would be great.

Answer 1

I found these article helpful for setting up login form with spring security, however, they do not use jsf:

http://www.mkyong.com/spring-security/spring-security-hello-world-example/ http://www.mkyong.com/spring-security/spring-security-form-login-example/

and found this article helpful for using ldap as authentication provider, it does not use ldapTemplate, but uses the spring-security configurations (spring-security.xml in the article)

Answer 2

This is how I am using LDAP for authentication:

1. Import Maven dependencies

    <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-ldap</artifactId> <version>4.0.2.RELEASE</version> </dependency> 

2. Write your implementation of WebSecurityConfigurerAdapter :

    @Configuration @EnableWebSecurity public class WebSecurityConfig extends WebSecurityConfigurerAdapter { private static final String SSO_HEADER = "AUTH_USER"; public static final String ADMIN = "ROLE_ADMIN"; public static final String USER = "ROLE_USER"; public static final String ANONYMOUS = "ROLE_ANONYMOUS"; @Autowired Environment env; @Override protected void configure(HttpSecurity http) throws Exception { http.authorizeRequests() .antMatchers("/css/**","/js/**","/images/**","/fonts/**","/api/**","/sendRedirect/**","/test/**").permitAll() .anyRequest().fullyAuthenticated().and().formLogin().loginPage("/login") .failureUrl("/login?error").permitAll() .and() .logout() .deleteCookies("remove") .invalidateHttpSession(true) .logoutUrl("/logout") .logoutSuccessUrl("/login?logout") .and() // Cross-site request forgery is turned off for RESTful API calls with the assumption that // authentication will be sufficient protection .csrf().ignoringAntMatchers("/api/**", "/space/{\\\\d+}/**", "/admin/**"); } @Override public AuthenticationManager authenticationManagerBean() throws Exception { return authenticationManager(); } @Configuration protected static class AuthenticationConfiguration extends GlobalAuthenticationConfigurerAdapter { @Autowired Environment env; @Override public void init(AuthenticationManagerBuilder auth) throws Exception { auth.ldapAuthentication().userDnPatterns("cn={0}") .contextSource(contextSource()); } @Bean public LdapContextSource contextSource() { LdapContextSource contextSource = new LdapContextSource(); contextSource.setUrl(env.getRequiredProperty("ldap.url")); contextSource.setBase(env.getRequiredProperty("ldap.base")); contextSource.setUserDn(env.getRequiredProperty("ldap.username")); contextSource.setPassword(env.getRequiredProperty("ldap.password")); return contextSource; } } }
