how to set default TGT file path

[Peng Hu PH Pei]

Put in krb5.conf and run kinit, the TGT is still in /tmp/:

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

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}'
