問題

ACL のアクセスが許可されていない場合でも、 CIFS 共有にアクセスできるユーザ
ユーザには「 setCbPrivilege 」権限があります

::> set diag ::*> diag secd authentication show-creds -node cdot-vsim1-01 -vserver svm -win-name test\user1 UNIX UID: pcuser <> Windows User: TEST\user1 (Windows Domain User) GID: pcuser Supplementary GIDs (partial): pcuser Primary Group SID: TEST\Domain Users (Windows Domain group) Windows Membership: TEST\Domain Users (Windows Domain group) Service asserted identity (Windows Well known group) BUILTIN\Users (Windows Alias) User is also a member of Everyone, Authenticated Users, and Network Users Privileges (0x2088): SeTcbPrivilege

共有の権限には、このユーザのアクセス権も表示されません
