Java Spring安全自定义ldap身份验证提供程序

我当前的ldap身份验证上下文设置如下：

    <ldap-server url="ldap://host/dn"
        manager-dn="cn=someuser"
        manager-password="somepass" />
    <authentication-manager>
        <ldap-authentication-provider user-search-filter="(samaccountname={0})"/>
    </authentication-manager> 

<bean id="contextSource"
    class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
    <constructor-arg value="ldaps://url/dc=mock,dc=com" />
    <property name="userDn" value="cn=username,ou=People,dc=mock,dc=com" />
    <property name="password" value="password" />
</bean>

<bean id="ldapAuthProvider"
    class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
    <constructor-arg>
        <bean
            class="org.springframework.security.ldap.authentication.BindAuthenticator">
            <constructor-arg ref="contextSource" />
            <property name="userDnPatterns">
                <list>
                    <value>uid={0},ou=People</value>
                </list>
            </property>
        </bean>
    </constructor-arg>
    <constructor-arg>
        <bean
            class="com.mock.MyCustomAuthoritiesPopulator">
        </bean>
    </constructor-arg>
</bean>

):


uid={0}，ou=人

但是，如何在安全上下文中将“ldapAuthProvider”引用到ldap服务器

我也在使用spring security 3，因此“”不存在…
我所做的只是将其添加到安全上下文中：

<authentication-manager>
     <authentication-provider ref='ldapAuthProvider'/>
</authentication-manager>



然后，按如下方式配置“ldapAuthProvider”bean：

    <ldap-server url="ldap://host/dn"
        manager-dn="cn=someuser"
        manager-password="somepass" />
    <authentication-manager>
        <ldap-authentication-provider user-search-filter="(samaccountname={0})"/>
    </authentication-manager> 

<bean id="contextSource"
    class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
    <constructor-arg value="ldaps://url/dc=mock,dc=com" />
    <property name="userDn" value="cn=username,ou=People,dc=mock,dc=com" />
    <property name="password" value="password" />
</bean>

<bean id="ldapAuthProvider"
    class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
    <constructor-arg>
        <bean
            class="org.springframework.security.ldap.authentication.BindAuthenticator">
            <constructor-arg ref="contextSource" />
            <property name="userDnPatterns">
                <list>
                    <value>uid={0},ou=People</value>
                </list>
            </property>
        </bean>
    </constructor-arg>
    <constructor-arg>
        <bean
            class="com.mock.MyCustomAuthoritiesPopulator">
        </bean>
    </constructor-arg>
</bean>


uid={0}，ou=人

MyCustomAuthoritiesPopulator的实现如下：

public class MyCustomAuthoritiesPopulator implements LdapAuthoritiesPopulator {
    public Collection<GrantedAuthority> getGrantedAuthorities(
            DirContextOperations arg0, String arg1) {       
           ArrayList<GrantedAuthority> list = new ArrayList<GrantedAuthority>();
            list.add((new SimpleGrantedAuthority("ROLE_USER"));
        return list;        
    }
}

公共类MyCustomAuthoritiesPopulator实现LdapAuthoritiesPopulator{
获得授权的公共收集机构(
DirContextOperations arg0，字符串arg1）{
ArrayList=新建ArrayList（）；
添加（（新的SimpleGrantedAuthority（“角色用户”））；
退货清单；
}
}
如果使用自定义的
LdapUserDetailsMapper
，则record spring配置更简单，因为
上有一个专用参数
用户上下文映射器ref
，允许您使用短配置样式：

  <authentication-manager>
      <ldap-authentication-provider
         user-search-filter="sAMAccountName={0}" 
         user-search-base="OU=Users"
         group-search-filter="(&amp;(objectclass=group)(member={0}))"
         group-search-base="OU=Groups"  
         user-context-mapper-ref="customUserContextMapper" />
  </authentication-manager>

  <ldap-server url="ldap://url:389/DC=mock,DC=com"
         manager-dn="manager" 
         manager-password="pass" />

如果您想避免难看的bean定义（DefaultSpringSecurityContextSource、LdapAuthenticationProvider、BindAuthenticator、+100）并使用“酷”的xml定义，如

<authentication-manager>
    <ldap-authentication-provider... />
</authentication-manager>

当我看到你的标题问题并阅读下面的信息时，我感到相当困惑。对我来说，身份验证与用户名和密码有关，而据我所知，你的实际问题是授权。下面的答案已经提到了这样的自定义填充器。你可以改为将文本更改为授权填充器吗？：）感谢您提供覆盖getAdditionalRoles的提示。我能够从AD LDAP检索嵌套组。SpringLDAP显然不支持这一点。
<ldap-server id="ldapServer" url="${ldap.url}" manager-dn="${ldap.manager.dn}"  manager-password="${ldap.manager.password}"/>

<authentication-manager>
    <ldap-authentication-provider user-search-filter="${ldap.userSearch.filter}" user-search-base="${ldap.searchBase}" 
        group-search-base="${ldap.groupSearchBase}"/>
</authentication-manager>
