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:

So for example, you could put in krb5.conf:

    default_ccache_name = FILE:/var/tmp/krb5cc_%{euid}

or at build time:

    ./configure DEFCCNAME='DIR:/var/krb5/%{username}'
