尽管已有多个问题,例如
Linux on Windows AD Domain我想知道如何使用开放源代码将Debian 6.0 Squeeze与AD集成,或者仅限商业用途工具免费使用
编辑：只有通过apt提供(安全)更新的工具才可以接受.
到目前为止,我已经能够通过kerberos获得实际的用户身份验证工作,例如日志显示用户名/密码检查成功,但用户无法登录,请参阅下面的日志摘录;
编辑：使用pam debug更新日志：

我的ldap.conf看起来像这样：

nsswitch.conf的：
# /etc/nsswitch.conf # # Example configuration of GNU Name Service Switch functionality. # If you have the `glibc-doc-reference' and `info' packages installed,try: # `info libc "Name Service Switch"' for information about this file. passwd: compat group: compat shadow: compat hosts: files dns ldap networks: files ldap protocols: db files services: db files ethers: db files rpc: db files netgroup: nis ldap passwd_compat: files ldap group_compat: files ldap shadow_compat: files ldap
所有/etc/pam.d都是由pam-auth-update创建的,所有三种(Kerberos,Unix和LDAP)身份验证方法都已选中.
我可以从数据包捕获中确认LDAP搜索结果是否正确用户信息,与下面显示的手动ldapsearch结果相同：

AD正在运行Windows 2k8(r2)服务器,所有debian软件包都是你从apt获得的.
任何想法都非常受欢迎.

如下所示,我尝试使用类似结果的sssd,现在要求密码两次,日志显示：

解决方法
我建议使用sssd.这是Debian挤压的标准包,让生活更轻松.安装sssd时,应该询问应该使用哪些身份验证方法.在那里进行选择,nsswitch.conf和pam.d脚本将自动更新.您需要掌握有关AD域的一些详细信息,但是,无论如何,您应该知道它们(例如,使用哪个DC以及kerberos域名是什么,等等).
相信我,我已经研究了很多(这个网站上的一些问题来自我),sssd就是答案.它甚至适用于笔记本电脑,因为凭据被缓存,您可以确定缓存的特征.
这是我们的sssd.conf文件,其中包含一些注释：
# SSSD configuration generated using /usr/lib/sssd/generate-config [sssd] config_file_version = 2 reconnection_retries = 3 sbus_timeout = 30 services = nss,pam domains = your.domain [nss] filter_groups = root filter_users = root reconnection_retries = 3 debug_level = 8 [pam] reconnection_retries = 3 debug_level = 8 [domain/<your.domain>] ; Using enumerate = true leads to high load and slow response enumerate = false cache_credentials = true #entry_cache_timeout = 60 id_provider = ldap auth_provider = krb5 chpass_provider = krb5 #access_provider = ldap ldap_uri = ldap://you.domain.controller ldap_search_base = CN=Users,DC=your,DC=domain ldap_tls_reqcert = demand ldap_tls_cacert = /etc/ssl/certs/ca-certificates.crt ldap_default_bind_dn = cn=LDAPsearch,CN=Users,dc=your,dc=domain ldap_default_authtok_type = password ldap_default_authtok = <password for LDAPsearch> ldap_pwd_policy = none ldap_user_object_class = user ldap_group_object_class = group ldap_user_home_directory = unixHomeDirectory krb5_kdcip = your.domain.controller krb5_realm = <kerberos realm name> krb5_changepw_principle = kadmin/changepw krb5_auth_timeout = 15
这是基于在Windows Server 2008中使用UNIX服务(现在它是其中不可或缺的一部分,曾经是2k3及更早版本中的加载项).
与其他LDAP系统不同,AD需要经过身份验证的会话才能检索到任何数据.我们已经创建了一个名为LDAPsearch的特殊用户来实现这一目标,但也可以使用实际的域用户来完成.
