30	  Secure RPC calls with Kerberos require an auxiliary user-space

40	default n
41	help
42	  Choose Y here to disable the use of deprecated encryption types
43	  with the Kerberos version 5 GSS-API mechanism (RFC 1964). The
44	  deprecated encryption types include DES-CBC-MD5, DES-CBC-CRC,
45	  and DES-CBC-MD4. These types were deprecated by RFC 6649 because
46	  they were found to be insecure.
47
48	  N is the default because many sites have deployed KDCs and
49	  keytabs that contain only these deprecated encryption types.
50	  Choosing Y prevents the use of known-insecure encryption types
51	  but might result in compatibility problems.
