0ed55bfe08 sync machine password to keytab: handle FreeIPA use case
FreeIPA uses own procedure to retrieve keytabs and during the setup of
Samba on FreeIPA client the keytab is already present, only machine
account needs to be set in the secrets database.

'sync machine password to keytab' option handling broke this use case by
always attempting to contact a domain controller and failing to do so
(Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=2309199).

The original synchronizing machine account password to keytab feature
did not have a mechanism to disable its logic at all.

d2a473a7b7 dsdb: Allow password history and password changes without an NT hash
We now allow this to be via the ENCTYPE_AES256_CTS_HMAC_SHA1_96 hash instead
which allows us to decouple Samba from the unsalted NT hash for
organisations that are willing to take this step (for user accounts).

(History checking is limited to the last three passwords only, as
ntPwdHistory is limited to NT hash values, and the PrimaryKerberosCtr4
package only stores three sets of keys.)

Since we don't store a salt per-key, but only a single salt, the check
will fail for a previous password if the account was renamed prior to a
newer password being set.

If the full DC does not support NTLMv2 authentication this forwarded password

plaintext, but we can not change the MS Windows behaviour, so we document this.
