我无法在python脚本中获取WinRM会话.

环境

ad-dns.test.com    - Windows 2012 AD and DNS Server
box88.test.com     - CentOS 7.2 : Kerberos, Python (Not joined to domain)
box62.test.com     - Windows 2012 R2 Standard (Joined to domain)
box63.test.com     - Windows 10 (Joined to domain)

配置

我通过ConfigureRemotingForAnsible.ps1 PowerShell脚本在Windows 10和2012服务器上启用了WinRM.这些是WinRM配置.

PS C:\Windows\system32> winrm get winrm/config

我已经准备好了CentOS盒子如下

# yum -y install python-pip python-devel krb5-devel krb5-libs krb5-workstation
# pip install --upgrade pip
# pip install  "pywinrm>=0.1.1" kerberos pykerberos requests-kerberos isodate xmltodict

# cat /etc/krb5.conf

 default_realm = TEST.COM

[realms]
 TEST.COM = {
  kdc = ad-dns.test.com
  admin_server   = ad-dns.test.com
  kpasswd_server = ad-dns.test.com
  default_domain = test.com
 }

[domain_realm]
 .test.com = TEST.COM
 test.com = TEST.COM
#

问题

到现在为止,一切都很顺利.当我尝试使用此kerberos票证使用以下脚本验证Windows服务器时,会出现此问题.

#!/usr/bin/env python

import winrm

s = winrm.Session('box63.test.com', auth=('vkumar@TEST.COM', 'IamUsingKerbTicket'), transport='kerberos')
r = s.run_cmd('ipconfig', ['/all'])
print r.status_code
print r.std_out
print r.std_err


# ./winrm_ipconfig.py
Traceback (most recent call last):
  File "./winrm_ipconfig.py", line 6, in <module>
    r = s.run_cmd('ipconfig', ['/all'])
  File "/usr/lib/python2.7/site-packages/winrm/__init__.py", line 37, in run_cmd
    shell_id = self.protocol.open_shell()
  File "/usr/lib/python2.7/site-packages/winrm/protocol.py", line 132, in open_shell
    res = self.send_message(xmltodict.unparse(req))
  File "/usr/lib/python2.7/site-packages/winrm/protocol.py", line 207, in send_message
    return self.transport.send_message(message)
  File "/usr/lib/python2.7/site-packages/winrm/transport.py", line 179, in send_message
    raise InvalidCredentialsError("the specified credentials were rejected by the server")
winrm.exceptions.InvalidCredentialsError: the specified credentials were rejected by the server
#

不确定,为什么我在Windows服务器上的事件日志显示成功时看到此错误.显然,我看到同时发生了三次登录和注销.

不知道我在这里缺少什么.在CentOS和&amp ;;上停止/禁用防火墙Windows机器和时间也同步.

解决方法:

最后解决了它,这是一个权限问题,而不是日志中指出的无效凭据.这个问题有两种解决方案

>将域用户添加到Domain Admins Group
>在Windows服务器上执行winrm configSDDL默认值,并检查读取和执行权限,如下所示
