- we need this to later:
- to disallow a StartTLS when TLS is already in use
- to place the TLS socket between the raw and sasl socket
when we had a sasl bind before the StartTLS
- and rfc4513 says that the server may allow to remove the TLS from
the tcp connection again and reuse raw tcp
- and also a 2nd sasl bind should replace the old sasl socket

routines to return an NTSTATUS. This should help track down errors.
Use a bit of talloc_steal and talloc_unlink to get the real socket to
be a child of the GENSEC or TLS socket.
Always return a new socket, even for the 'pass-though' case.

contexts from the application layer into the socket layer.
This improves a number of correctness aspects, as we now allow LDAP
packets to cross multiple SASL packets. It should also make it much
easier to write async LDAP tests from windows clients, as they use SASL
by default. It is also vital to allowing OpenLDAP clients to use GSSAPI
against Samba4, as it negotiates a rather small SASL buffer size.
This patch mirrors the earlier work done to move TLS into the socket
layer.
Unusual in this pstch is the extra read callback argument I take. As
SASL is a layer on top of a socket, it is entirely possible for the
SASL layer to drain a socket dry, but for the caller not to have read
all the decrypted data. This would leave the system without an event
to restart the read (as the socket is dry).
As such, I re-invoke the read handler from a timed callback, which
should trigger on the next running of the event loop. I believe that
the TLS code does require a similar callback.
In trying to understand why this is required, imagine a SASL-encrypted
LDAP packet in the following formation:
+-----------------+---------------------+
| SASL Packet #1 | SASL Packet #2 |
----------------------------------------+
| LDAP Packet #1 | LDAP Packet #2 |
----------------------------------------+
In the old code, this was illegal, but it is perfectly standard
SASL-encrypted LDAP. Without the callback, we would read and process
the first LDAP packet, and the SASL code would have read the second SASL
packet (to decrypt enough data for the LDAP packet), and no data would
remain on the socket.
Without data on the socket, read events stop. That is why I add timed
events, until the SASL buffer is drained.
Another approach would be to add a hack to the event system, to have it
pretend there remained data to read off the network (but that is ugly).
In improving the code, to handle more real-world cases, I've been able
to remove almost all the special-cases in the testnonblock code. The
only special case is that we must use a deterministic partial packet
when calling send, rather than a random length. (1 + n/2). This is
needed because of the way the SASL and TLS code works, and the 'resend
on failure' requirements.

Finally acknowledge that ldb is inherently async and does not have a dual personality anymore
Rename all ldb_async_XXX functions to ldb_XXX except for ldb_async_result, it is now ldb_reply
to reflect the real function of this structure.
Simo.

The function pointer was meant to be unused, this patch fixes
partition.c to use ldb_sequence_number(). (No backend provided the
pointer any more).
Set the flags onto the ldb structure, so that all backends opened by
the partitions module inherit the flags.
Set the read-ony flag when accessed as the global catalog
Modify the LDAP server to track that this query is for the global
catalog (by incoming port), and set a opqaue pointer.
Next step is to read that opaque pointer in the partitions module.

This reduces caller complexity, because the TLS code is now called
just like any other socket. (A new socket context is returned by the
tls_init_server and tls_init_client routines).
When TLS is not available, the original socket is returned.

even context again. We need to ensure we don't process packets until
we are finished setting up the connection, have the ldb in place etc.
We may need to do the same in other servers.

By freeing the request you will be sure everything down the path get freed.
this also means you have to steal the results if you want to keep them :)

Applications that use LDB modules will now have to run ldb_global_init()
before they can use LDB.
The next step will be adding support for loading LDB modules from .so
files. This will also allow us to use one LDB without difference between the
standalone and the Samba-specific build

Currently only ldb_ildap is async, the plan
is to first make all backend support the async calls,
and then remove the sync functions from backends and
keep the only in the API.
Modules will need to be transformed along the way.

The problem was that the supportedControls were being stolen into the
result sent to the client, then talloc_free()ed. This caused them to
be invalid on the next rootDSE query.
This also tries to avoid attaching the result to the long-term samdb
context, and avoids an extra loop in the result processing (pointed
out by tridge).

structure that is more generic than just 'IP/port'.
It now passes make test, and has been reviewed and updated by
metze. (Thankyou *very* much).
This passes 'make test' as well as kerberos use (not currently in the
testsuite).
The original purpose of this patch was to have Samba able to pass a
socket address stucture from the BSD layer into the kerberos routines
and back again. It also removes nbt_peer_addr, which was being used
for a similar purpose.
It is a large change, but worthwhile I feel.
