Normally samba_wdc_get_pac() is used to generate the PAC for a TGT, but

If we decided not to put a PAC into the ticket, mspac would be NULL
here, and the resulting ticket would not contain a PAC. This could
happen if there was a request to omit the PAC or the service did not
require authorization data. Ensure that we always generate a PAC.

Windows ignores PAC_TYPE_ATTRIBUTES_INFO and always issues a PAC when
presented with an RODC-issued TGT. By removing this PAC buffer from
RODC-issued tickets, we ensure that an RODC-issued ticket will still
result in a PAC if it is first renewed or validated by the main DC.

To use memcpy(), we need to specify the number of bytes to copy, rather
than the number of ldb_val structures.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=15008
Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>
Currently, we can crash the server by sending a large number of values
of a specific attribute (such as sAMAccountName) spread across a few
message elements. If val_count is larger than the total number of
elements, we get an access beyond the elements array.
Similarly, we can include unrelated message elements prior to the
message elements of the attribute in question, so that not all of the
attribute's values are copied into the returned elements values array.
This can cause the server to access uninitialised data, likely resulting
in a crash or unexpected behaviour.

This aims to minimise usage of the error-prone pattern of searching for

BUG: https://bugzilla.samba.org/show_bug.cgi?id=15009
Signed-off-by: Joseph Sutton <josephsutton@catalyst.net.nz>
Using the newly added ldb flag, we can now detect when a message has
been shallow-copied so that its elements share their values with the
original message elements. Then when adding values to the copied
message, we now make a copy of the shared values array first.
This should prevent a use-after-free that occurred in LDB modules when
new values were added to a shallow copy of a message by calling
talloc_realloc() on the original values array, invalidating the 'values'
pointer in the original message element. The original values pointer can
later be used in the database audit logging module which logs database
requests, and potentially cause a crash.

authenticate_ldap_simple_bind*() needs to pass the
result of the cracknames operation into the auth stack
as user_info->client.{account,domain}_name, because
user_info->client.{account,domain}_name is also used
when forwarding the request via netrLogonSamLogon*
to a remote server, for exactly that the values are
also used in order to map a AUTH_PASSWORD_PLAIN into
AUTH_PASSWORD_RESPONSE, where the NTLMv2 response
contains the account and domain names passed in the
netr_IdentityInfo value.
Otherwise it would not be possible to forward the
LDAP simple bind authentication request to a remote
DC.
Currently this only applies to an RODC that forwards
the request to an RWDC.
But note that LDAP simple binds (as on Windows) only
work for users in the DCs forest, as the DsCrackNames
need to work and it can't work for users of remote
forests. I tested that in a DC of a forest root domain,
if rejected the LDAP simple bind against a different forest,
but allowed it for a users of a child domain in the
same forest. The NTLMSSP bind worked in both cases.
