is
.Dv NULL ,
the service of the credentials are always compared. If the client
name in
.Fa mcreds
is present, the client names are also compared. This function is
normally only called indirectly via
.Xr krb5_cc_retrieve_cred 3 .

.It KRB5_TC_MATCH_KEYTYPE
Compare enctypes.
.It KRB5_TC_MATCH_FLAGS_EXACT
Make sure that the ticket flags are identical.
.It KRB5_TC_MATCH_FLAGS
