A user accesses a file via NFS and is denied access, even though the file's permissions appear to grant access to the user's UID. The administrator checks the file's ACL and sees that the ACL contains a SID, not a UID. What is the most likely reason for the access denial?

The ID mapping is not configured to translate the SID in the ACL to a UID for NFS access.

The NFS client is not configured to use Kerberos, so it cannot resolve the SID.

The file's permissions are set to 600, which denies access to all users except the owner.

The user's UID is not in the NFS client's local passwd file.

In PowerScale, where are ID mapping rules applied to control how identifiers are translated?

To individual files and directories

An administrator is setting up a new PowerScale cluster that will be used exclusively by Unix clients via NFS. There is no Active Directory or LDAP in the environment. What is the simplest and most appropriate ID mapping configuration?

Use the default mapping, which passes through the UID directly without translation.

Configure UID-to-SID mapping, even though there are no Windows clients.

Configure SID-to-UID mapping, even though there are no Windows clients.

Disable ID mapping entirely, as it is only needed for mixed-protocol environments.
