适用场景

  • ONTAP 9.12.1及更高版本
  • NFS
  • CIFS 本地用户和组

问题描述

  • 升级到ONTAP 9.12.1及更高版本后、挂载或访问 先前可访问的目录时、用户将被拒绝访问
  • 安全跟踪表示:

Access is denied because the UNIX user could not be mapped to a valid NT user while reading the user's access rights on an object.

  • 目标卷路径中的一个卷采用NTFS安全模式、其中可能包括根卷

::> vol show -vserver svm1 -volume svm1_root -fields security-style
vserver     volume        security-style
------------- ------------------ --------------
svm1          svm1_root          ntfs

使用该服务

  • 被拒绝访问的Unix帐户会显式映射到本地Windows帐户

::> vserver name-mapping show -vserver svm1 -direction unix-win
Vserver:   svm1
Direction: unix-win
Position Hostname      IP Address/Mask
-------- ---------------- ----------------
1     -          -           Pattern: root
                      Replacement: SVM1\\Administrator

  • 本地帐户 已禁用、这是预配置的CIFS本地用户"Administrator (管理员)"的默认帐户

    ::> local-user show -fields is-account-disabled
      (vserver cifs users-and-groups local-user show)
    vserver       user-name           is-account-disabled
    ------------- ------------------- -------------------
    svm1          SVM1\Administrator true
