Gwenael already pointed out the KRB5CCNAME environment variable. In
addition, MIT krb5 1.11 adds the default_ccache_name krb5.conf variable
with parameter expansion and the DEFCCNAME configure parameter. These
two new variables support parameter expansion as documented here:
http://web.mit.edu/kerberos/krb5-latest/doc/admin/conf_files/krb5_conf.html#parameter-expansion
So for example, you could put in krb5.conf:
[libdefaults]
default_ccache_name = FILE:/var/tmp/krb5cc_%{euid}
or at build time:
./configure DEFCCNAME='DIR:/var/krb5/%{username}'
