Unix root 用户无法访问 ONTAP 9 中的 NTFS 卷，因为"UNIX 用户 'root' 的名称映射失败"

适用于

问题描述

此问题可以以多种方式表现：

• 当 NFS 客户端尝试以 root (UID 0) 用户身份访问 NTFS 卷时，他们可能会被拒绝访问/权限被拒绝

示例 for secd authentication show-creds

Error: Get user credentials procedure failed [ 0 ms] Determined UNIX id 0 is UNIX user 'root' [ 0] Trying to map 'root' to Windows user 'root' using implicit mapping [ 1] Using a cached connection to domain.local [ 2] Could not find Windows name 'root' **[ 2] FAILURE: Name mapping for UNIX user 'root' failed with transient errors.

示例： 
Error: Get user credentials procedure failed
[  2018] Determined UNIX id 0 is UNIX user 'root'
[  2018] Mapping Successful for Unix-user 'root' to Windows user '<username>' at position 1
[  2750] Hostname found in Name Service Cache
[  2754] Successfully connected to ip <IP>, port 445 using TCP
[  2761] Successfully connected to ip <IP>, port 88 using TCP
[  2770] Successfully authenticated with DC <DC>
[  2793] Could not find Windows name '<AD>\<username>'
[  2793] FAILURE: Name mapping for UNIX user 'root' failed. Explicit Mapping failed and no default mapping found

• Sectrace 确认：

Node Index Filter Details Reason --------------- ----- -------------------------- ------------------------------ LDSNASPA6-01 1 Security Style: NTFS and Access is denied because the NT ACL UNIX user could not be mapped to a valid NT user while reading the user's access rights on an object.

• 如果 SVM 的根卷是 NTFS 并且 NFS 客户端正在访问 SVM 下的 UNIX 卷，则它们可能会被拒绝访问
