An Isilon administrator is receiving “permission denied” while accessing a file on a cluster that an end-user created through an SMB share. The end-user is unable to access the share from their UNIX server.
The end-user “mydomain.com\win_user1” as the login name to access the Microsoft Windows share and then used an LDAP account name of “ux_user1” to access the UNIX mount.

• A.Usermapping rule is not present.
• B.RFC2307 is not configured on the Active Directory.
• C.On-disk identity is set as “Native”.
• D.Fake UID generation in the cluster is disabled.
