Some clients (e.g. an exchange server) check operatingSystemVersion
in order to check if a domain controller is new enough.
So we better use a value matching the dc functional level.
While we also fixed operatingSystem[Version] at provision time,
we do it also in dsdb_check_and_update_fl() in order to
handle old provisions and systems joined to an existing domain.

Arrays of SIDs are handled not fully consistently throughout the
codebase. Sometimes SIDs in the first and second positions represent a
user and a primary group respectively; other times they don't mean
anything in particular. Using these index constants in situations of the
former sort can help to clarify our intent.

Group expansion, performed in dsdb_expand_nested_groups(), now

groups receive the SE_GROUP_RESOURCE bit in the attributes which are now
carried alongside each group SID.
Whereas before, in auth_convert_user_info_dc_sambaseinfo() and
auth_convert_user_info_dc_saminfo6(), we invariantly used the flag
combination SE_GROUP_MANDATORY | SE_GROUP_ENABLED_BY_DEFAULT |
SE_GROUP_ENABLED to set attributes in the PAC, we now take the correct

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.
