Here we can fetch the right key, and check if the PAC is likely to be signed by a key that
we know. We cannot check the KDC signature on incoming trusts.

thi ensures we are using the header corresponding to the version of
ldb we're linking against. Otherwise we could use the system ldb for
link and the in-tree one for include

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.

The PAC was being regenerated on all normal DCs, because they don't
have a msDS-SecondaryKrbTgtNumber attribute. Instead we need to check
if it's set and not equal to our RODC number, allowing RODCs to trust
the full DCs and itself, but not other RODCs.

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

It is much easier to do decryption with wireshark when the keytab is
available for every host in the domain. Running 'net export keytab
<keytab name>' will export the current (as pointed to by the supplied
smb.conf) local Samba4 doamin.
(This uses Heimdal's 'hdb' keytab and then the existing hdb-samba4,
and so has a good chance of keeping working in the long term).
Andrew Bartlett
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)
Andrew Bartlett
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.
Andrew Bartlett
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.
Andrew Bartlett
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.

This change utilizes the addition of the e_data parameter to the windc_plugin in
the heimdal code to pass extended information back to the client. The extended
information is provided in an e-data block as part of the kerberos error
message, and allows the client to determine which specific error condition
occurred.
(This used to be commit 502466ba950bfd104518b9eb9586896c1e076343)
The enhanced mappings allow the Windows client to determine whether a user's
password needs to be changed (and allows them to change it), or if they cannot
logon at all.
Changes still need to be made to allow additional data to be returned. Windows
uses that additional data to display more detailed dialogs to the user. The
additional information is returned in an e-data struct of type PA-PW-SALT that
contains the more-detailed NTSTATUS error code.
(This used to be commit 6a98e5a7aa0cdbb61358901df50162b5b914ee5c)
There are still a few tidyups of old FSF addresses to come (in both s3
and s4). More commits soon.

This patch updates our build system and glue to support a new snapshot
of lorikeet-heimdal.
We now procude a [SUBSYTEM] in the ans1_deps.pl script, and can depend
on that in the heimdal_build/config.mk. This is much easier than
listing every generated .o file individually.
This required some small changes to the build system, due to the way
the parent directory was handled for the output of scripts. I've also
cleaned up et_deps.pl to handle cleaning up it's generated files on
clean.
The PAC glue in Heimdal has changed significantly: we no longer have a
custom hack in the KDC, instead we have the windc plugin interface.
As such, pac-glue.c is much smaller. In the future, when I'm
confident of the new code, we will also be able to 'downsize'
auth/kerberos/kerberos_pac.c.
(I'll include the updated copy of heimdal in the next chekin, to make
it clearer what's changed in Samba4 itself).
