Allows access to the mounted directories using only the security flavors listed. Security methods supported are as follows:
UNIX-style security, which is based on UIDs and GIDs.
Kerberos Version 5 authentication, which verifies the identity of the users accessing the storage system on all accesses and also verifies to the client that the responses are from the storage system.
Kerberos Version 5 integrity, which provides a strong assurance that the messages have not been tampered with.
Kerberos Version 5 privacy, which ensures that messages intercepted on the wire cannot be read by any other party.
The integrity and privacy services both include authentication.
