Choose Y here to enable Secure RPC using the Kerberos version 5
|
|
GSS-API mechanism (RFC 1964).
|
|
|
|
Secure RPC calls with Kerberos require an auxiliary user-space
|
|
daemon which may be found in the Linux nfs-utils package
|
|
available from http://linux-nfs.org/. In addition, user-space
|
|
Kerberos support should be installed.

|

If unsure, say Y.

Choose Y to enable the use of deprecated Kerberos 5

encryption types that utilize Data Encryption Standard

(DES) based ciphers. These include des-cbc-md5,

des-cbc-crc, and des-cbc-md4, which were deprecated by

RFC 6649, and des3-cbc-sha1, which was deprecated by RFC

These encryption types are known to be insecure, therefore

the default setting of this option is N. Support for these

encryption types is available only for compatibility with

legacy NFS client and server implementations.
|

Removal of support is planned for a subsequent kernel

release.
