.Sh DESCRIPTION
|
|
The
|
|
.Nm krb5_verify_init_creds
|
|
function verifies the initial tickets with the local keytab to make
|
|
sure the response of the KDC was spoof-ed.
|
|
.Pp
|
|
.Nm krb5_verify_init_creds
|
|
will use principal
|
|
.Fa ap_req_server
|
|
from the local keytab, if
|
|
.Dv NULL
|
|
is passed in, the code will guess the local hostname and use that to
|
|
form host/hostname/GUESSED-REALM-FOR-HOSTNAME.
|
|
.Fa creds
|
|
is the credential that
|
|
.Nm krb5_verify_init_creds
|
|
should verify.
|
|
If
|
|
.Fa ccache
|
|
is given
|
|
.Fn 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.
|
|
.Pp
|
|
.Fn krb5_verify_init_creds_opt_init
|
|
cleans the the structure, must be used before trying to pass it in to
|
|
.Fn krb5_verify_init_creds .
|
|
.Pp
|
|
.Fn krb5_verify_init_creds_opt_set_ap_req_nofail
|
|
controls controls the behavior if
|
|
.Fa 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.
