NAME
krb5_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);
DESCRIPTION
krb5_compare_creds() compares mcreds (usually filled in by the application) to creds (most often from a credentials cache) and return TRUE if they are equal. Unless mcreds-server is NULL, the service of the credentials 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 comparing 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.
