This moves the evaluation of the SASL mechansim list to display in the
rootDSE to the ldap server.

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.

will not use it anyway as we plan to support
partitions in ldb directly like with rootdse
Merge ldap_simple_ldb into ldap_backend, it is
not simple anymore and makes no sense to have
it separated now that ldap partitions are gone
Initial attempt at working to some limit to avoid DOSs
for the ldap server.
Simo.

fact that INIT_OBJ_FILES include smb_build.h will be sufficient to
have recompiles at the right time.

The partitioning logic is still there, but we only have one
partition. If we need partitioning in the future it might be better to
remove this partitioning code and use a partitioning module instead

authenticated session down into LDB. This associates a session info
structure with the open LDB, allowing a future ldb_ntacl module to
allow/deny operations on that basis.
Along the way, I cleaned up a few things, and added new helper functions
to assist. In particular the LSA pipe uses simpler queries for some of
the setup.
In ldap_server, I have removed the 'ldasrv:hacked' module, which hasn't
been worked on (other than making it continue to compile) since January,
and I think the features of this module are being put into ldb anyway.
I have also changed the partitions in ldap_server to be initialised
after the connection, with the private pointer used to associate the ldb
with the incoming session.

w2k3 dc join working
I just commit that to not lose it if my home box would crash...
you need a hacked.ldb with some stuff in it, I'll explain later
and you need --option="ldapsrv:hacked=yes"
so what is left now is KRB5 support for DCERPC in the server
as the EVENT LOG of w2k3 says...
