* krb_get_lrealm takes a pointer to a string, and a number, n. It fills
* in the string, r, with the name of the nth realm specified on the
* first line of the kerberos config file (KRB_CONF, defined in "krb.h").
* It returns 0 (KSUCCESS) on success, and KFAILURE on failure. If the
* config file does not exist, and if n=1, a successful return will occur
* with r = KRB_REALM (also defined in "krb.h").
*
* NOTE: for archaic & compatibility reasons, this routine will only return
* valid results when n = 1.
*
* For the format of the KRB_CONF file, see comments describing the routine
* krb_get_krbhst().
