Symptoms

以下是 setspn 选项的错误示例： 
svc_cifssupport <NAS_server_name> -sets -add <SPN> -compname <comp_name> -domain <full_domain_name> -admin <admin_name> 
<NAS_server_name> : Enter Password for <admin_name>: Pa!!sword$

-----
SetSpn::getAdminCreds: gss_acquire_cred_ext failed: Miscellaneous failure. Preauthentication failed.
SetSpn::ModifySpn(add): Failed to get Admin creds for user <admin_name>

Error 4020: <NAS_server_name> : failed to complete command
-----

Cause

Unity CLI 不直接接受某些特殊字符。

某些svc_cifssupport命令要求指定域管理员用户的密码。当域帐户密码包含特殊字符时，这些命令将失败，除非执行其他步骤来说明特殊字符。

可能导致失败的选项包括：

-nltest 选项（检查 SMB 服务器上
的网络登录）-setspn 选项（管理给定系统名称的 Windows 安全主体）

Resolution

使用 -nltest 选项时，如果密码括在单引号 （'） 中，并且 $ 等特殊字符使用反斜杠 （\） 进行转义，则命令会成功。 
svc_cifssupport <NAS_server_name> -nltest -nb  <comp_name> -user <user_name> -dom <domain> -usrpwd 'Pa!!sword\$'

使用 -setspn 选项时，使用反斜杠 （\） 转义特殊字符就足够了。无需将密码括在单引号 （'） 中。 
svc_cifssupport <NAS_server_name> -sets -add <SPN> -compname <comp_name> -domain <full_domain_name> -admin <admin_name> 
<NAS_server_name> : Enter Password for <admin_name>: Pa!!sword\$
