SYNOPSIS
struct krb5_verify_init_creds_opt; krb5_verify_init_creds_opt *options krb5_verify_init_creds_opt *options int ap_req_nofail 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 its true, the error will be ignored. Note that this use is possible insecure.
