If the security style is UNIX, CIFS client file access is determined by which of the following?

If the security style is UNIX, CIFS client file access is determined by which of the following?

• A. NT ACLs
• B. the last client to set permissions
• C. the mapped UNIX UID/GID of the CIFS client and the UNIX file permissions
• D. This is not allowed: A CIFS client cannot access files in a path set to a security style of UNIX

Answer: (C)

On a UNIX security style volume, CIFS access is governed by UNIX-style permissions and the CIFS client's mapped UNIX identity. NetApp maps the Windows user to a UNIX UID and GID, and then checks the file’s UNIX permissions (owner, group, others) along with the user’s identity and group memberships. If the UID/GID mapping and the permission bits allow access, the client is granted it; if not, access is denied. NT ACLs aren’t used for access decisions under UNIX security style, and it’s possible for a CIFS client to access a file if the UNIX permissions permit it.
