如果Windows用户具有大写字符、则隐式Windows到UNIX名称映射将失败

适用场景

ONTAP 9

问题描述

在以下情况下、Windows到UNIX名称映射将失败：

• 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、使用隐式名称映射。如果在Windows到UNIX方向上使用隐式名称映射、则Windows用户名将转换为所有小写字符。

如果在CIFS选项(例如pcuser)中定义了默认UNIX用户、则在运行diag secd authentication show-creds时、映射将显示为"pcuser"。如果CIFS选项中未定义默认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)
