This overloads the 'name' part of the keytab name to supply a context
pointer, and so avoids 3 global variables!
To do this, we had to stop putting the entry for kpasswd into the
secrets.ldb. (I don't consider this a big loss, and any entry left
there by an upgrade will be harmless).

This removes the last use of the prefix hdb_ldb and makes it clear
that we pass in 3 global variables to get state information into
hdb_samba4 when used as a keytab. (And that they belong to
hdb_samba4, not to the KDC)

To do this properly, we must use the PAC, but for now this is enough
to check that we are delegating to another name on the same host
(which must be safe).
(Windows 7 does this a lot, also noted in bug 6273)

Each attribute we request from LDB comes with a small cost, so don't
lookup any more than we must for the (very) frequent krbtgt lookup
case. Similarly, we don't need to build a PAC for a server (as a
target), so don't ask for the PAC attributes here either.

The LDB_ prefix is misleading, and stomps on the LDB namespace. This
is a Samba4 hdb module, and not something generic.

Soon we will add implementations for these.

The previous code only allowed an KRB5_NT_ENTERPRISE name (an e-mail
list user principal name) in an AS-REQ. Evidence from the wild
(Win2k8 reportadely) indicates that this is instead valid for all
types of requests.
While this is now handled in heimdal/kdc/misc.c, a flag is now defined
in Heimdal's hdb so that we can take over this handling in future (once we start
using a system Heimdal, and if we find out there is more to be done
here).

The function LDB_lookup_principal() has been eliminated, and it's
contents spread back to it's callers. Removing the abstraction makes
the code clearer.
Also ensure we never pass unescaped user input to a LDB search
function.

This requires a rework on Heimdal's windc plugin layer, as we want
full control over what tickets Heimdal will issue. (In particular, in
case our requirements become more complex in future).
The original problem was that Heimdal's check would permit the ticket,
but Samba would then deny it, not knowing it was for kadmin/changepw
Also (in hdb-samba4) be a bit more careful on what entries we will
make the 'change_pw' service mark that this depends on.

A number of heimdal functions and constants have changed since we last
imported a tree (for the better, but inconvenient for us).

Logs showed that every SAM authentication was causing a non-indexed
ldb search for member=XXX. This was previously indexed in Samba4, but
since we switched to using the indexes from the full AD schema it now
isn't.
The fix is to use the extended DN operations to allow us to ask the
server for the memberOf attribute instead, with with the SIDs attached
to the result. This also means one less search on every
authentication.
The patch is made more complex by the fact that some common routines
use the result of these user searches, so we had to update all
searches that uses user_attrs and those common routines to make sure
they all returned a ldb_message with a memberOf filled in and the SIDs
attached.

It turns out (seen in MS-SAMR 3.1.1.7.1 for example) that the primary
way the krbtgt account is recognised as special is that RID. This
should fix issues such as 'password expired' on the kpasswd service.

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.

When starting GENSEC on the server, the auth subsystem context must be
passed in, which now includes function pointers to the key elements.
This should (when the other dependencies are fixed up) allow GENSEC to
exist as a client or server library without bundling in too much of
our server code.

We supply this to krb5 as a plugin, so we must keep it around as long

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.

This avoids one more custom patch to the Heimdal code, and provides a
more standard way to produce hdb plugins in future.
I've renamed from hdb_ldb to hdb_samba4 as it really is not generic
ldb.

The previous ldb_search() interface made it way too easy to leak results,

This uses Heimdal's PAC parsing code in the:
- LOCAL-PAC test
- gensec_gssapi server
- KDC (where is was already used, the support code refactored from here)
In addition, the service and KDC checksums are recorded in the struct
auth_serversupplied_info, allowing them to be extracted for validation
across NETLOGON.
