34 * This program is invoked from t_pwhist.py to simulate some conditions
35 * normally only seen in databases created before krb5 1.3. With the "make"
36 * argument, the history key is rolled over to a kvno containing two keys
37 * (since krb5 1.3 we ordinarily ensure that there's only one). With the
38 * "swap" argument, the two history keys are swapped in order; we use this
39 * operation to simulate the case where krb5 1.7 or earlier chose something
40 * other than the first history key to create password history entries.
