The GET_CHECK_STR macro (now unrolled) did not initialise the trusts->array[n].dns_name
when the value was not set. New tests for our trusted domains code create
domain trusts without a DNS domain name. Found by the autobuild flakey build detector.

This is needed to complete the transition from "samdb_msg_add_string" to
"ldb_msg_add_string".
And this patch yields better NTSTATUS error results than before
(INVALID_PARAMETER rather than OUT_OF_MEMORY).

This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc. This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.
The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.

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.

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).
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).

After looking at the s4 side of the (s)channel :) I found out that it makes
more sense to simply make it use the tdb based code than redo the same changes
done to s3 to simplify the interface.
Ldb is slow, to the point it needs haks to pre-open the db to speed it up, yet
that does not solve the lookup speed, with ldb it is always going to be slower.
Looking through the history it is evident that the schannel database doesn't
really need greate expanadability. And lookups are always done with a single
Key. This seem a perfet fit for tdb while ldb looks unnecessarily complicated.
The schannel database is not really a persistent one. It can be discared during
an upgrade without causing any real issue. all it contains is temproary session
data.
Make the initial schannel check logic more understandable.
Make it easy to define different policies depending on the caller's
security requirements (Integrity/Privacy/Both/None)
This is the same change applied to s3
Simo, I'm not really sure that those checks are valid. I read MS-NRPC section
3.5.4.1 about LOGONSRV_HANDLEs ("server_name" is of this type). There isn't
stated that the server name has necessarily to be in the DNS form and should
also be valid when it's NULL (if DCE server and client are the same - I don't
know if me make use of it in s4).
Actually return trust relationships by searching the appropriate
entries in the SAM database.
Add checks and return the correct flags, type and attributes.
This reverts commit 87b6f2e863.
This was the cause of the breakage of the "LogonGetDomainInfo" testsuite. I
think my behaviour is more correct to Windows Server since the test works
against it (at least release 2003 R2).
One problem I discovered is that freshly joined workstations don't get their
DNS name into the directory. Therefore I think also another part (maybe another
RPC call) is able to do this.
This allows us to reuse a ldb context if it is open twice, instead
of going through the expensive process of a full ldb open. We can
reuse it if all of the parameters are the same.
The change relies on callers using talloc_unlink() or free of a parent
to close a ldb context.
This patch adds a system_session cache, preventing us from having to
recreate it on every ldb open, and allowing us to detect when the same
session is being used in ldb_wrap
For KERBEROS applications the realm should be upcase (function "lp_realm") but
for DNS ones it should be used lowcase (function "lp_dnsdomain"). This patch
implements the use of both in the right way.
Vista and upper version use this value to check wether they should ask the DC
to change the msDS-SupportedEncryptionTypes attribute or not.
Declare the different value as a bitmap in Netlogon idl
This check is specified in Windows Server after release 2003.
The parameter "hostname" should match as prefix of the dns hostname given as
parameter in the "workstation" structure.
- Correctly use samdb_search_string to do a 'base' search
(this needs a NULL, not a "" argument for the format string)
- There is no need (and it caused a security hole) to use
talloc_asprintf() with the only argument being the string to
duplicate.

This addresses bug #4888 and #6596 in SAMBA 4 Bugzilla
- It implements the call in the complete form as specified in the MSPP/WSPP docs
and on the discussion on the "cifs-protocol" list
- Therefore client informations (OS name, OS version, "servicePrincipalName"...)
are now saved in the AD each time the client invokes the call
In the SAMBA 4 DCE/RPC NETLOGON server the SAM context references have generally
the type "void *". But we know that those context objects are based on the "struct
ldb_context" type. We've always to cast for using a SAM/LDB call.
This I didn't find very appealing and so I assigned the right (detailed) type to each "sam_ctx".
Therefore, the casts could disappear.
Also this change is only cosmetic.
Patch for bug #4939
This refactors the NETLOGON code related to this bug:
- Introduces a new "SYNCSTATE" enum required by the "DatabaseSync2" call (acc.
to WSPP)
- Make "DatabaseSync" dependant from "DatabaseSync2" (acc. to WSPP)
- Let "DatabaseSync2" return NT_STATUS_NOT_IMPLEMENTED (I'm not sure if this is
also true when a domain is running in mixed mode)
- Make "LogonControl" and "LogonControl2" dependant form "LogonControl2Ex"
(acc. to WSPP)
- Let "LogonControl2Ex" return WERR_NOT_SUPPORTED for now
A single AD server can only host a single domain, so don't stuff about
with looking up our crossRef record in the cn=Partitions container.
We instead trust that lp_realm() and lp_workgroup() works correctly.

Win7-beta.
The first problem is that we removed the dnsDomain attribute a while
back, so we were returning NULL for two fields. We now return the
realm.
The second problem is that Win7-beta sends the domain in the form the
user typed it, so it may be in either the short or long form. We check
for the short form and convert if needed.
This uses a virtual attribute 'clearTextPassword' (name chosen to
match references in MS-SAMR) that contains the length-limited blob
containing an allegidly UTF16 password. This ensures we do no
validation or filtering of the password before we get a chance to MD4
it. We can then do the required munging into UTF8, and in future
implement the rules Microsoft has provided us with for invalid inputs.
All layers in the process now deal with the strings as length-limited
inputs, incluing the krb5 string2key calls.
This commit also includes a small change to samdb_result_passwords()
to ensure that LM passwords are not returned to the application logic
if LM authentication is disabled.
The objectClass module has been modified to allow the
clearTextPassword attribute to pass down the stack.

In doing so, I realised we still used 'dnsDomain', which is not part
of the standard schema (now removed).
We also set the 'wrong' side of the linked attributes for the
masteredBy on each partition - this is now set in provision_self_join
and backlinks via the linked attributes code.
When we have the schema loaded, we must also have a valid domain SID
loaded, so that the objectclass module works. This required some ejs
glue.

and NT passwords are not required.

This patch changes a lot of the code in ldb_dn.c, and also
removes and add a number of manipulation functions around.
The aim is to avoid validating a dn if not necessary as the
validation code is necessarily slow. This is mainly to speed up
internal operations where input is not user generated and so we
can assume the DNs need no validation. The code is designed to
keep the data as a string if possible.
The code is not yet 100% perfect, but pass all the tests so far.
A memleak is certainly present, I'll work on that next.
Simo.

This commit cleans up a number of aspects of the LSA interface.
Firstly, we do 2 simple searches on opening the LSA policy, to obtain
the basic information we need. This also avoids us searching for
dnsDomain (an invented attribute).
While I was at it, I added and tested new LSA calls, including the
enumTrustedDomainsEx call. I have also merged the identical structures
lsa_DomainInformation and lsa_DomainList.

Andrew Bartlett
(This used to be commit 341a0abeb4)
The new RPC-SCHANNEL test shows that the full credentials state must
be kept in some shared memory, for some length of time. In
particular, clients will reconnect with SCHANNEL (after loosing all
connections) and expect that the credentials chain will remain in the
same place.
To achive this, we do the server-side crypto in a transaction,
including the fetch/store of the shared state.
