We check the ACB_PW_EXPIRED bit to determine whether the account is
expired. Since ACB_PW_EXPIRED can’t be represented in a 16‐bit integer,
we must increase the width of acct_flags so as not to lose that bit.

In configurations where vfs_acl_xattr is used with 'ignore system acls'
option we encounter NT_STATUS_ACCESS_DENIED while trying to open an
already existing test_dir in smb2.delete-on-close-perms.READONLY. Due
to missing SEC_STD_DELETE permission from the list of allowed ACEs it
couldn't be removed via previous call to smb2_deltree(). Thus as seen
with other tests we now call set_dir_delete_perms() so that subsequent
attempt to remove it can succeed.

In shares where acl_xattr vfs module is loaded with 'ignore system acls'
set, smb2.delete-on-close-perms.FIND_and_set_DOC fails to open test_dir
due to NT_STATUS_ACCESS_DENIED as it lacks few permissions for owner
when created using create_dir(). Test case aims to set delete-on-close
for which delete permission is necessary in first place. Therefore we
now perform the creation and subsequent opening of directory using
torture_smb2_testdir() so that the open handle comes with SEC_STD_DELETE
permission.

This is a measure to avoid multiple servers rotating the password
but means that the maximum password age really must be set to
twice the TGT lifetime, eg a default of 20 hours. The internet
suggestions of 1 day for this feature should work fine.

This is to gracefully deal with races and to avoid additional password
rollover in situations where the TGT lifetime is longer than the
maximum password lifetime. This is not a sensible combination, so
we just avoid the extra DB write, and update it only once per AS-REQ
in this case.

This ensures that before the KDC starts to process the entry
we check if it is expired and rotate it. As an account with
UF_SMARTCARD_REQUIRED simply can not expire unless
msDS-ExpirePasswordsOnSmartCardOnlyAccounts is set and
the Domain Functional Level is >= 2016 we do not need
to do configuration checks here.

This makes the time during authentication stay consistent in the KDC
and follows the fake time when we are testing gMSA accounts. By having
the account expiry follow exactly the same clock as the password expiry
we can hope for less supprises.
