如果我们需要从ActiveDirectory中获取用户属性(例如名称,sn等),则不能使用Specialized LDAP身份验证提供程序进行配置,该提供程序使用Active Directory配置约定,例如“ springframework.security.ldap.authentication.ad.ActiveDirectoryLdapAuthenticationProvider”

 @Override
    protected void configure(HttpSecurity http) throws Exception {

            http.csrf().disable().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                        .authorizeRequests().antMatchers("/", "logout").permitAll().and().httpBasic();
    }


     @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception { 

            auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider());
        }

     @Bean
        public AuthenticationManager authenticationManager() {

         return new ProviderManager(Arrays.asList(activeDirectoryLdapAuthenticationProvider()));
        }

     @Bean
        public AuthenticationProvider activeDirectoryLdapAuthenticationProvider() {

            ActiveDirectoryLdapAuthenticationProvider adProvider = new ActiveDirectoryLdapAuthenticationProvider(domain, url);
            adProvider.setConvertSubErrorCodesToExceptions(true);
            adProvider.setUseAuthenticationRequestCredentials(true);

            return adProvider;
        }

,然后使用AuthenticationManager,如下所示。

Authentication auth = new UsernamePasswordAuthenticationToken(userName, password);
        Authentication a = authenticationManager.authenticate(auth);

但是,对于正确的用户名和密码,我得到a.isAuthenticated()为true,也为我的用户名得到a.getName()。但是,如何检索sn,dispalyname,name和其他属性。我们是否需要编写一个CustomActiveDirectoryLdapAuthenticationProvider,如此处所述 http://code-addict.pl/active-directory-spring-security/

您没有。 Spring Security带有一个this界面

/**
 * Creates a fully populated UserDetails object for use by the security framework.
 *
 * @param ctx the context object which contains the user information.
 * @param username the user's supplied login name.
 * @param authorities
 * @return the user object.
 */
UserDetails mapUserFromContext(DirContextOperations ctx, String username,
        Collection<? extends GrantedAuthority> authorities);

默认实现UserDetailsContextMapper

当前仅映射搜索返回的组。

// Map the roles
for (int i = 0; (this.roleAttributes != null)
        && (i < this.roleAttributes.length); i++) {
    String[] rolesForAttribute = ctx.getStringAttributes(this.roleAttributes[i]);

    if (rolesForAttribute == null) {
        this.logger.debug("Couldn't read role attribute '"
                + this.roleAttributes[i] + "' for user " + dn);
        continue;
    }
        for (String role : rolesForAttribute) {
        GrantedAuthority authority = createAuthority(role);
            if (authority != null) {
            essence.addAuthority(authority);
        }
    }
}

但是,实现自己的 UserDetailsMapper 可以检索从LDAP返回的所有记录。

您只需确定要获取的属性

Object attribute = ctx.getObjectAttribute("some-ldap-attribute");

这是在身份验证事件期间获取自定义值的方式。

如果您只想查询和搜索LDAP目录中的数据,则可以利用LdapUserDetailsMapper

它旨在模仿 RestTemplate 对于HTTP(对于LDAP)的作用。
