krb5_verify_init_creds_opt_init, krb5_verify_init_creds_opt_set_ap_req_nofail, krb5_verify_init_creds -- verifies a credential cache is cor-

LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS
#include <krb5.h>
struct krb5_verify_init_creds_opt;
void
krb5_verify_init_creds_opt_init(krb5_verify_init_creds_opt *options);

krb5_verify_init_creds(krb5_context context, krb5_creds *creds, krb5_principal ap_req_server, krb5_ccache *ccache,
krb5_verify_init_creds_opt *options);
DESCRIPTION
The krb5_verify_init_creds function verifies the initial tickets with the local keytab to make sure the response of the KDC was spoof-ed.
krb5_verify_init_creds will use principal ap_req_server from the local keytab, if NULL is passed in, the code will guess the local hostname
and use that to form host/hostname/GUESSED-REALM-FOR-HOSTNAME. creds is the credential that krb5_verify_init_creds should verify. If ccache
is given krb5_verify_init_creds() stores all credentials it fetched from the KDC there, otherwise it will use a memory credential cache that
is destroyed when done.
krb5_verify_init_creds_opt_init() cleans the the structure, must be used before trying to pass it in to krb5_verify_init_creds().
krb5_verify_init_creds_opt_set_ap_req_nofail() controls controls the behavior if ap_req_server doesn't exists in the local keytab or in the
KDC's database, if it's true, the error will be ignored. Note that this use is possible insecure.

Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Does this mean that it will run on any shell ?
