5a6f3fcf81 auth4: Fix map_user_info_cracknames for domain==NULL
DsCrackNameOneName directly fails for DRSUAPI_DS_NAME_FORMAT_NT4_ACCOUNT
if the name passed in does not contain a \. The only caller of
map_user_info_cracknames (auth_check_password_send) passes in
lpcfg_workgroup(), which does not contain a \. Add in the \ also for
the default_domain case.

795f4729ca auth: keep track of lastLogon and lastLogonTimestamp
lastLogon is supposed to be updated for every interactive or kerberos
login, and (according to testing against Windows2012r2) when the bad
password count is non-zero but the lockout time is zero. It is not
replicated.

lastLogonTimestamp is updated if the old value is more than 14 -
random.choice([0, 1, 2, 3, 4, 5]) days old, and it is replicated. The
14 in this calculation is the default, stored as
"msDS-LogonTimeSyncInterval", which we offer no interface for
changing.

The authsam_zero_bad_pwd_count() function is a convenient place to
update these values, as it is called upon a successful logon however
that logon is performed. That makes the function's name inaccurate, so
we rename it authsam_logon_success_accounting(). It also needs to be
told whet5her the login is interactive.

The password_lockout tests are extended to test lastLogon and
lasLogonTimestamp.

eba8799514 auth: Remove .get_challenge (only used for security=server)
With NTLMSSP, for NTLM2 we need to be able to set the effective challenge,
so if we ever did use a module that needed this functionlity, we would
downgrade to just NTLM.

Now that security=server has been removed, we have no such module.

This will make it easier to make the auth subsystem async, as we will
not need to consider making .get_challenge async.
