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
