Kerberos configuration file

When I install Kerberos to connect MHPCC machine, krb5 configuration needs to be edited. The location of krb5.conf is by default /usr/local/krb5. However, I got an error message like:

kinit(v5): Configuration file does not specify default realm when parsing name ........

This error has been resolved by copying

/usr/local/krb5/krb5.conf

to

/etc/krb5.conf

or
/etc/kerberosV/krb5.conf

Symbolic link did not work.
