KRB5_VERIFY_INIT_CRED... BSD Library Functions Manual KRB5_VERIFY_INIT_CRED...

NAME
     krb5_verify_init_creds_opt_init,
     krb5_verify_init_creds_opt_set_ap_req_nofail, krb5_verify_init_creds --
     verifies a	credential cache is correct by using a local keytab

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);

     void
     krb5_verify_init_creds_opt_set_ap_req_nofail(krb5_verify_init_creds_opt *options,
	 int ap_req_nofail);

     krb5_error_code
     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 be-
     havior 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.
