DES transition
The Data Encryption Standard (DES) is widely recognized as weak. The
krb5-1.7 release contains measures to encourage sites to migrate away
from using single-DES cryptosystems. Among these is a configuration
variable that enables "weak" enctypes, which defaults to "false"
beginning with krb5-1.8.
