This reverts commit 8a2ce5c47c.
Jelmer pointed out that these are also in use by other LDB databases - not only
SAMDB ones.

The issue here is that we have not yet first cast to int32_t explicitly,
before we cast to an signed int to printf() into the %d or cast to a
int64_t before we then cast to a long long to printf into a %lld.
There are *no* unsigned integers in Active Directory LDAP, even the RID
allocations and ms-DS-Secondary-KrbTgt-Number are *signed* quantities.
(See the schema, and the syntax definitions in schema_syntax.c).
The failure has been detected by Matthieu Patou on the buildfarm host "tridge"
due to a malformed "groupType" attribute.
The solution is to use the "%d" specifier. Either to use it directly - or better
(when possible) use the call "samdb_msg_add_uint" (which encapsulates it).
This patch changes such problematic situations.
This can be substituted by "ldb_msg_add_value".

We have ldb_msg_find_attr_as_* calls which do exactly the same. Therefore this
reduces only code redundancies.

The merged I plan in this area require spliting security.h into
two header files, a common header and a session.h for the
remaining source4-specific code.

A new event context is constructed by LDB when required for secrets.ldb
This will be essentially unused, as LDB on TDB will only trigger 'fake'
events, and blocks on transactions and lock operations anyway.
Andrew Bartlett
We intend to see always all objects with the "show_deleted" control specified.
To see also recycled objects (beginning with 2008_R2 function level) we need to
use the new "show_recycled" control.
As far as I see this is only internal code and therefore we don't run into
problems if we do substitute it.

This implements partial attribute set checking on getncchanges. If the
client sends a partial_attribute_set then we only return the specified
attributes.
This also implements access checking on the NC root for the access
right GUIDs for requests with and without reveal secrets

use:
dcesrv:stubs directory = .
to save files like this:
RPC-netlogon-48-pullfail.dat

developer builds
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
the unbind method is only called when the dcesrv_connection_context is
being destroyed (its called from the destructor). That means that priv
is either already free, or is about to be freed, so don't free it
again
These are related, but slightly different concepts. The biggest difference
is that rights are not enumerated as a system-wide list.
This moves the rights to security.idl due to dependencies.
Andrew Bartlett
Now that privileges are no longer given luid values sequentially,
we need another way to look them up for enumeration.

in case we are handling extended operation.
It seems that windows accept both DRSUAPI_EXOP_ERR_SUCCESS
and DRSUAPI_EXOP_ERR_NONE, but Samba is a little bit
more picky on this.
Most of extended operations I know of work like:
1. do extended operation
2. collect a set of objects to return and start replication cycle
3. continue returning object as we have no more to give
This way we ensure we are doing 1. only once
This adds support for DRSUAPI_EXOP_FSMO_REQ_ROLE, DRSUAPI_EXOP_FSMO_RID_REQ_ROLE
and DRSUAPI_EXOP_FSMO_REQ_PDC.
Developed in collaboration with Anatoliy Atanasov <anatoliy.atanasov@postpath.com>
When DRSUAPI_EXOP_FSMO_RID_ALLOC extended op is handled
in DsGetNCChanges() stub, we need to returned a well know set of
object - see: [ms-adts], 3.1.1.5.1.7
With this hack we are going to return just objects modified
during RID allocation procedure - i.e. "RID Manager$", "RID Set" for
computer object and computer object itself.
Which is a close approximation of what we are expected to return.
This makes the structure much more like NT_USER_TOKEN in the source3/
code. (The remaining changes are that privilages still need to be merged)
Andrew Bartlett
when we deny a EXOP_REPL_SECRET call we should set the exop error code
to NONE, and the main return code to WERR_DS_DRA_ACCESS_DENIED (based
on observing windows server behaviour)

The rules for when a RODC can replicate secrets are:
- it can always replicate its own acct
- it can also replicate its krbtgt acct
- it can't replicate other krbtgt accts
- it can't replicate interdomain trust accounts
- it can't replicate users in the denied group list
- it can replicate users in the allowed group list
otherwise it can't replicate

When a RODC uses extended getncchanges operation
DRSUAPI_EXOP_REPL_SECRET it gets an override on the ability to
replicate the secret attributes.
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
The getncchanges call needs to be able to access the sam as the system
user for RODC clients. To do this it needs a sam_ctx connection with
system credentials

Depending on which NC is being replicated, GetNCChanges() returns
either ATTID based on local prefixMap or msDs-IntId value of
the attributeSchema class for the attribute being replicated.
If set, msDs-IntId value is always returned when replicating
object form NC other than Schema NC.
Objects in Schema NC replica always use prefixMap based ATTIDs.
w2k8r2 is setting this bit as a RODC. Instead of refusing the
replication, we now remove the bit from req8, which means other places
in the code that check this bit can stay the same

The flags field of message elements is part of a set of flags. We had
LDB_FLAG_MOD_MASK for extracting the type, but it was only rarely
being used (only 1 call used it correctly). This adds
LDB_FLAG_MOD_MASK() to make it more obvious what is going on.
This will allow us to use some of the other flags bits for internal
markers on elements
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
This also changes the calling convention slightly - we should always
allocate this with talloc_zero() to allow some elements to be
optional. Some elements may only make sense in Samba3, which I hope
will use this common structure.
Andrew Bartlett
this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

Windows gives them in chunks, but I don't know the correct
rule to calculate the chunk size.
For now I'll use 1500 as the max size.
Windows isn't happy when it gets ~ 100000 linked attributes in one
response. It corrupts its directory index and later moves some objects
to the LostAndFound folder.

Obviously the last attempt wasn't enough. Now we do really only read the first
byte in the address buffer which on little endian transmission does always
contain the address family (MS-NRPC 2.2.1.2.4.1).
This should now be working platform-independently.
This should make it clearer by the use of the standardised "sa_family_t" type
and hopefully fixes the problems on platforms other than Linux (NetBSD in the
buildfarm for example).
The biggest change consists in the implementation of the Windows Server
return size formula MIN(*r->out.num_entries, 1+(r->in.max_size/SAMR_ENUM_USERS_MULTIPLIER).
Windows 2000 does strictly request header signing on some requests also if the
server doesn't provide it. But there is a small trick (don't reset the actual
session info) to make these special RPC operations work without a full header
signing implementation.
This fixes for example the list of domain groups in local groups when displayed
sing the local user/group management tool.
And this should finally fix bug #7113.
The patch was inspired by another one by tridge and abartlet: http://gitweb.samba.org/samba.git/?p=tridge/samba.git;a=commitdiff;h=2dc19e2878371264606575d3fc09176776be7729
"size_t" counters aren't really needed here (we don't check data lengths).
And we save the result in a certain "num_sids" variable which is of type
"unsigned".
This is a rewrite of the lookup_rids code, using a query based on the
extended DN for a clearer interface.
By splitting this out, the logic is able to be shared, rather than
copied, into a passdb wrapper.

This is a rewrite of the group membership lookup code, using the
stored extended DNs to avoid doing the lookup into each member to find
the SID
By splitting this out, the logic is able to be shared, rather than

Andrew Bartlett
Adapt the two functions for the restructured "password_hash" module. This
means that basically all checks are now performed in the mentioned module.
An exception consists in the SAMR password change calls since they need very
precise NTSTATUS return codes on wrong constraints ("samr_password.c") file
w2k8r2 returns the local DC information on no inputs for
getDcNameEx2. This is needed for starting dsa.msc (ADUC) on
Win7.
CDLAP on the same call returns an error. This uses a parameter
fill_on_blank_request to distinguish the two cases.
When we aren't a DC we shouldn't have the netlogon pipe available.
[MS-NRPC 1.3] says that we can only have DCs on the server side.

This implementation checks if the domainname is valid for us or a trusted domain.
Then I've also added the PDC location functionality. That means that we should
return "WERR_NO_SUCH_DOMAIN" (MS-NRPC 3.5.5.2.5).

During building an object to send it on a GetNCChanges reply, it checks
the attributes and if any of them is a RODC filtered and the recipient
is a RODC, then such attribute is not sent.

This patch creates the samdb_is_rodc() function, which looks for
the NTDSDSA object for a DC that has a specific invocationId
and if msDS-isRODC is present on such object and it is TRUE, then
consider the DC as a RODC.
The new samdb_rodc() function uses the samdb_is_rodc() function
for the local server.
