我正在尝试使用 Samba 和 Winbind 设置具有 Active Directory 身份验证的文件服务器。
域控制器是 Windows 2000 SP4（不作判断）。
文件服务器是 Debian 7.7（最新稳定版）。这是全新安装，仅安装了一些指南库和依赖项推荐的程序。Samba 是从源代码构建的，具有以下参数：
./configure --with-acl-support --with-ads --with-shared-modules=idmap_ad --disable-cups --disable-iprint
root@this-server:~# samba --version
Version 4.1.13
root@this-server:~# winbindd --version
Version 3.6.6
root@this-server:~# klist -V
Kerberos 5 version 1.10.1
kinit 管理员、net ads join -k、net ads testjoin、getent passwd、getent group、wbinfo -u、wbinfo -g、id DomainUser、chown DomainUser:DomainGroup、chgrp DomainUser:DomainGroup - 全部正常，无错误。
我可以使用域凭据通过 ssh 登录。
smbclient -k -L any-other-host - 也有效。
然而...
root@this-server:~# smbclient -k -L this-server -d 3
