NFS Access Control Lists support

The AIX® NFS version 4 implementation supports two ACL types: NFS4 and AIXC.

The authoritative source for access checking lies in the underlying file system exported by the NFS server. The file system takes into consideration the file's access controls (ACLs or permission bits), the caller's credentials, and other local system restrictions that might apply. Applications and users should not assume that examination of UNIX mode bits or ACLs alone can be used to conclusively predict access.

The aclget, aclput, and acledit commands can be used on the client to manipulate either NFS or AIX ACLs. For more information, see Access Control Lists in Security.
