带有多个Active Directory服务器的Grails Spring Security LDAP插件

Question

我有Grails Spring Security插件连接到一个Active Directory服务器没有问题.但是,我需要连接到多个服务器.我们在一台AD服务器上有一些用户,在另一台服务器上有其他用户,因此我们需要尝试在两个位置查找用户.

例如,在Java中,我的工作如下:

<authentication-manager>
    <authentication-provider ref="provider1"/>
    <authentication-provider ref="provider2"/>
...
</authentication-manager>

<ldap-server id="provider1"
             url="ldap://LDAPSERVER1.mycompany.intranet"
             manager-dn="OU=std_users,OU=users,DC=mycompany,DC=intranet"
             manager-password="blah"/>

<ldap-server id="provider2"
             url="ldap://DIFFERENT_LDAPSERVER.mycompany.intranet"
             manager-dn="OU=std_users,OU=external_users,DC=mycompany,DC=intranet"
             manager-password="blah"/>

在Grails中,我可以配置一个AD服务器,但无法确定如何配置多个:

// LDAP config
grails.plugin.springsecurity.ldap.context.managerDn = 'CN=blah,OU=std_users,OU=users,DC=mycompany,DC=intranet'
grails.plugin.springsecurity.ldap.context.managerPassword = 'the_password'
grails.plugin.springsecurity.ldap.context.server = 'ldap://theserver.mycompany.intranet'

grails.plugin.springsecurity.ldap.authorities.ignorePartialResultException = true // typically needed for Active Directory
grails.plugin.springsecurity.ldap.search.base = 'OU=std_users,OU=users,DC=mycompany,DC=intranet'
grails.plugin.springsecurity.ldap.search.filter="sAMAccountName={0}" // for Active Directory you need this
grails.plugin.springsecurity.ldap.search.searchSubtree = true
grails.plugin.springsecurity.ldap.auth.hideUserNotFoundExceptions = false

我知道你可以创建一个以空格分隔的服务器列表,但是这对我来说不起作用,因为它只有一个连接后才会尝试其中一个服务器,而我需要它来尝试在两者中寻找用户.

我想我可能需要陷入resources.groovy文件,但不知道从哪里开始 - 有没有人配置多个AD位置？

我唯一的另一个想法是创建一个虚拟目录,将一个目录中的所有用户聚集在一起.有谁能建议这样做的好方法？我一直在看http://myvd.sourceforge.net/usecases.html

任何帮助,将不胜感激.一直在谷歌搜索,我没有更接近解决方案.

安德鲁的回答指出了我正确的方向,我现在有这个工作.

使用ActiveDirectoryLdapAuthenticationProvider可以更轻松地完成这项工作.这样做如下:

在resources.groovy:

// Domain 1
ldapAuthProvider1(ActiveDirectoryLdapAuthenticationProvider,
        "mydomain.com",
        "ldap://mydomain.com/"
)

// Domain 2
ldapAuthProvider2(ActiveDirectoryLdapAuthenticationProvider,
        "mydomain2.com",
        "ldap://mydomain2.com/"
)

在Config.groovy中:

grails.plugin.springsecurity.providerNames = ['ldapAuthProvider1', 'ldapAuthProvider2']

这是您需要的所有代码.您几乎可以删除Config.groovy中的所有其他grails.plugin.springsecurity.ldap.*设置,因为它们不适用于此AD设置.

有关文档,请参阅:http: //docs.spring.io/spring-security/site/docs/3.1.x/reference/springsecurity-single.html#ldap-active-directory

如果您不使用AD并且想要"纯LDAP"版本:

在resources.groovy:

// Create another ldap authentication provider
ldapAuthProvider2(org.springframework.security.ldap.authentication.LdapAuthenticationProvider,
        ref("ldapAuthenticator2"),
        ref("ldapAuthoritiesPopulator") // Use default
) {
    // Can set other auth provider settings here
}

ldapAuthenticator2(org.springframework.security.ldap.authentication.BindAuthenticator, ref("contextSource2")) {
    userSearch = ref("ldapUserSearch2")
}

// Set up the manager to read LDAP
contextSource2(DefaultSpringSecurityContextSource, grailsApplication.config.grails.plugin.springsecurity.ldap.context.server2) {
    userDn = grailsApplication.config.grails.plugin.springsecurity.ldap.context.managerDn2 // Manager DN
    password = grailsApplication.config.grails.plugin.springsecurity.ldap.context.managerPassword2
}

// Configuration for searching for user
ldapUserSearch2(FilterBasedLdapUserSearch, grailsApplication.config.grails.plugin.springsecurity.ldap.search.base2, grailsApplication.config.grails.plugin.springsecurity.ldap.search.filter2, ref('contextSource2')) {
}

然后在Config.groovy中:

// Config for second LDAP AuthenticationProvider - used in resources.groovy
grails.plugin.springsecurity.ldap.context.managerDn2 = 'CN=MANAGER_USER,OU=Users,DC=mycompany,DC=com'
grails.plugin.springsecurity.ldap.context.managerPassword2 = 'manager_password'
grails.plugin.springsecurity.ldap.context.server2 = "ldap://the-ldap-server.com"

grails.plugin.springsecurity.ldap.search.base2 = 'OU=Users,DC=mycompany,DC=com'
grails.plugin.springsecurity.ldap.search.filter2 = "sAMAccountName={0}" // for Active Directory you need this

// Add the AuthenticationProvider to the list
grails.plugin.springsecurity.providerNames = ['ldapAuthProvider', 'ldapAuthProvider2']
