Thank you. I was wondering about how I had coded that. I changed to
code to use the function you recommended to get the krb5_keytab
handle:
krb5_keytab keytab;
retval = krb5_kt_resolve(context, "FILE:/usr/lib/postgresql/8.2/etc/
krb5.keytab", &keytab);
if (retval != 0){
return (1);
}
krb5_get_in_tkt_with_keytab(context,
KRB5_DEFAULT_OPTIONS,
(krb5_address **) 0,
(krb5_enctype *) 0,
(krb5_preauthtype *) 0,
keytab,
(krb5_ccache) 0,
creds, &kdc_rep);
Unfortunately, I am still getting the "Failed to read a valid file
image from memory" error. I will look through krb.h to see if there
may be any other preparatory functions that I am missing. In the
meantime, if anyone has any ideas about where my code is going wrong,
I'd be happy to hear them.
SIncerely,
Angus
