KRB5_COMPARE_CREDS(3) BSD Library Functions Manual KRB5_COMPARE_CREDS(3)NAMEkrb5_compare_creds — compare Kerberos 5 credentials
LIBRARY
Kerberos 5 Library (libkrb5, -lkrb5)
SYNOPSIS
#include <krb5.h>
krb5_boolean
krb5_compare_creds(krb5_context context, krb5_flags whichfields,
const krb5_creds *mcreds, const krb5_creds *creds);
DESCRIPTIONkrb5_compare_creds() compares mcreds (usually filled in by the applica‐
tion) to creds (most often from a credentials cache) and return TRUE if
they are equal. Unless mcreds->server is NULL, the service of the cre‐
dentials are always compared. If the client name in mcreds is present,
the client names are also compared. This function is normally only called
indirectly via krb5_cc_retrieve_cred(3).
The following flags, set in whichfields, affects the comparison:
KRB5_TC_MATCH_SRV_NAMEONLY Consider all realms equal when compar‐
ing the service principal.
KRB5_TC_MATCH_KEYTYPE Compare enctypes.
KRB5_TC_MATCH_FLAGS_EXACT Make sure that the ticket flags are
identical.
KRB5_TC_MATCH_FLAGS Make sure that all ticket flags set in
mcreds are also present in creds.
KRB5_TC_MATCH_TIMES_EXACT Compares the ticket times exactly.
KRB5_TC_MATCH_TIMES Compares only the expiration times of
the creds.
KRB5_TC_MATCH_AUTHDATA Compares the authdata fields.
KRB5_TC_MATCH_2ND_TKT Compares the second tickets (used by
user-to-user authentication).
KRB5_TC_MATCH_IS_SKEY Compares the existance of the second
ticket.
