Windows 到 UNIX 名称映射失败，如果：

Windows 和 UNIX 用户名包含大写字符
没有为 WIN-UNIX 方向定义显式名称映射规则。

在这种情况下，将使用隐式名称映射。当 Windows 到 UNIX 方向使用隐式名称映射时， Windows 用户名将转换为所有小写字符。

如果在 CIFS 选项（如 PCUser ）中定义了默认 UNIX 用户，则在运行 diag secd 身份验证 show-creds 时，映射将显示为 "pcuser" 。如果在 CIFS 选项中未定义任何默认 UNIX 用户，则可能会报告类似以下内容的错误：

Filer::*> diag secd authentication show-creds -node Filer-01 -vserver testsvm -win-name TestUser

Vserver: testsvm (internal ID: 11)
