Kerberos 加入 Active Directory 域失败 (uBuntu)答案

【问题标题】：Kerberos Join Active Directory Domain Failure (uBuntu)Kerberos 加入 Active Directory 域失败 (uBuntu)

【问题描述】：

我尝试在 Ubuntu 12.04.05 中加入 Active Directory 和 Samba 4。
当我运行host -t SRV _kerberos._udp.test.sg 时出现错误：

Host _kerberos._udp.test.sg not found: 3(NXDOMAIN)

同时

$# host -t SRV _ldap._tcp.test.sg 
_ldap._tcp.test.sg has SRV record 0 0 389 4ecapsvsg6.test.sg.
$# host -t A 4ECAPSVSG6.test.sg
4ECAPSVSG6.test.sg has address 10.153.64.5

我的/etc/samba/smb.conf：

# Global parameters
[global]
   workgroup = TEST
   realm = TEST.SG
   netbios name = 4ECAPSVSG6
   server role = active directory domain controller
   dns forwarder = 10.153.64.5
   security = ads
   use kerberos keytab = true
   password server = 4ecapsvsg6.test.sg
   allow dns updates = nonsecure and secure
   bind interfaces only = no
   server services = +smb -s3fs
   dcerpc endpoint servers = +winreg +srvsvc
   passdb backend = samba4
   server services = smb, rpc, nbt, wrepl, ldap, cldap, kdc, drepl, winbind, ntp_signd, kcc, dnsupdate, dns

我的/etc/krb5.conf：

[libdefaults]
    default_realm = TEST.SG
    krb4_config = /etc/krb.conf
    krb4_realms = /etc/krb.realms
    kdc_timesync = 1
    ccache_type = 4
    forwardable = true
    proxiable = true
[realms]
     4ECAP.SG = {
          kdc = 4ecapsvsg6.test.sg:88
          admin_server = 4ecapsvsg6.test.sg:749
          default_domain = test.sg
    }
[domain_realm]
    .test.sg = TEST.SG
    test.sg = TEST.SG
[login]
    krb4_convert = true
    krb4_get_tickets = false

我的/etc/hosts：

  127.0.0.1       localhost
  127.0.1.1       4ecapsvsg6
  # The following lines are desirable for IPv6 capable hosts
  ::1     ip6-localhost ip6-loopback
  fe00::0 ip6-localnet
  ff00::0 ip6-mcastprefix
  ff02::1 ip6-allnodes
  ff02::2 ip6-allrouters
  10.153.64.5     4ecapsvsg6.test.sg     4ecapsvsg6

解决办法是什么？没有它，我无法使用命令运行加入域：

sudo net ads join

出现类似的错误

Failed to join domain: failed to lookup DC info for domain 'TEST' over rpc: Logon failure

我做了kinit administrator和klist，结果：

   Ticket cache: FILE:/tmp/krb5cc_0
   Default principal: administrator@TEST.SG
    Valid starting       Expires              Service principal
    26/03/2015 14:29:04  27/03/2015 00:29:04  krbtgt/TEST.SG@TEST.SG
    renew until 27/03/2015 14:29:00

同时我包括我的/etc/resolv.conf

   # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
   #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

   nameserver 10.153.64.5
   search test.sg
   domain test.sg

【解决方案1】：

上周我在谷歌上搜索后，很幸运我找到了这个网站http://edoceo.com/howto/samba4

恰好是我需要编辑我的 dnsmasq (/etc/dnsmasq.conf) 添加这一行：

srv-host=_kerberos._tcp.test.sg,4ecapsvsg6.test.sg,88 srv-host=_kerberos._tcp.dc._msdcs.test.sg,4ecapsvsg6.test.sg,88 srv-host=_kerberos._udp.test.sg,4ecapsvsg6.test.sg,88

srv-host=_kpasswd._tcp.test.sg,4ecapsvsg6.test.sg,464 srv-host=_kpasswd._udp.test.sg,4ecapsvsg6.test.sg,464

并禁用 Bind9（默认与 Samba4 一起安装）

现在问题消失了 :)

只剩下一个问题，如何连接到 AD（我将为此打开另一个线程）
