Prior to the 1.11 release, there is no config file setting for the
default credential cache.  The only discovery mechanisms are the
KRB5CCNAME environment variable (which is often set by the login system,
if pam_krb5 is in use) and the hardcoded default of /tmp/krb5cc_NNNN.

In the 1.11 release, the default credential cache can be specified in
the [libdefaults] section of /etc/krb5.conf with the default_ccache_name
variable.  The value is subject to parameter expansion as described here:
