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).

Andrew Bartlett
(This used to be commit 13c9df1d4f)
This merges Samba4 with lorikeet-heimdal, which itself has been
tracking Heimdal CVS for the past couple of weeks.
This is such a big change because Heimdal reorganised it's internal
structures, with the mechglue merge, and because many of our 'wishes' have been granted: we now have DCE_STYLE GSSAPI, send_to_kdc hooks and many other features merged into the mainline code. We have adapted to upstream's choice of API in these cases.
In gensec_gssapi and gensec_krb5, we either expect a valid PAC, or NO
PAC. This matches windows behavour. We also have an option to
require the PAC to be present (which allows us to automate the testing
of this code).
This also includes a restructure of how the kerberos dependencies are
handled, due to the fallout of the merge.

We do need the gsskrb5_get_initiator_subkey() routine. But we should
ensure that we do always get a valid key, to prevent any segfaults.

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.

This extracts a remote windows domain into a keytab, suitable for use
in ethereal for kerberos decryption.
For the moment, like net samdump and net samsync, the 'password

server. eg:
password server = ncacn_np:mypdc

This allows a new password to be written in, and old entries removed
(we keep kvno and kvno-1).

We now put the PAC in the AS-REP, so that the client has it in the
TGT. We then validate it (and re-sign it) on a TGS-REQ, ie when the
client wants a ticket.
This should also allow us to interop with windows KDCs.
If we get an invalid PAC at the TGS stage, we just drop it.
I'm slowly trying to move the application logic out of hdb-ldb.c, and
back in with the rest of Samba's auth system, for consistancy. This
continues that trend.

authentication. This pulls the creating of the keytab back to the
credentials code, and removes the special case of 'use keberos keytab
= yes' for now.
This allows (and requires) the callers to specify the credentials for
the server credentails to GENSEC. This allows kpasswdd (soon to be
added) to use a different set of kerberos credentials.
The 'use kerberos keytab' code will be moved into the credentials
layer, as the layers below now expect a keytab.
We also now allow for the old secret to be stored into the
credentials, allowing service password changes.
Andrew Bartlett
(This used to be commit 205f77c579)
at the Samba4 socket layer.
The intention here is to ensure that other events may be processed while
heimdal is waiting on the KDC. The interface is designed to be
sufficiently flexible, so that the plugin may choose how to time
communication with the KDC (ie multiple outstanding requests, looking
for a functional KDC).
I've hacked the socket layer out of cldap.c to handle this very
specific case of one udp packet and reply. Likewise I also handle
TCP, stolen from the winbind code.
This same plugin system might also be useful for a self-contained
testing mode in Heimdal, in conjunction with libkdc. I would suggest
using socket-wrapper instead however.
Andrew Bartlett
(This used to be commit 3b09f9e8f9)
I still have issues with Win2k3 SP1, and Samba4 doesn't pass it's own
test for the moment, but I'm working on these issues :-)
This required a change to the credentials API, so that the special
case for NTLM logins using a principal was indeed handled as a
special, not general case.
Also don't set the realm from a ccache, as then it overrides --option=realm=.

on the kerberos mailing lists a couple of weeks ago: Don't use DNS at

Andrew Bartlett

ideas I have had.
When I get a full list of things I want to do to a krb5_context I'll
either add gsskrb5_ wrappers, or a way of speicfying the krb5 context
per gssapi context.
(I want to ensure that the only krb5_context variables created while
executing Samba4 are via our wrapper).
Andrew Bartlett
(This used to be commit 8a22d46e70)
about the size of the signature. In particular, this works with AES,
which was previously broken Samba4/Samba4.
Reviewed by metze (and thanks for help with the previous IDL commit).
(This used to be commit 3c8be196cc)
with an aim to make the code simpiler and more correct.
Gone is the old (since the very early Samba 3.0 krb5 days) 'iterate over
all keytypes)' code in gensec_krb5, we now follow the approach used in
gensec_gssapi, and use a keytab.
I have also done a lot of work in the GSSAPI code, to try and reduce
the diff between us and upstream heimdal. It was becoming hard to
track patches in this code, and I also want this patch (the DCE_STYLE
support) to be in a 'manageable' state for when lha considers it for
merging. (metze assures me it still has memory leak problems, but
I've started to address some of that).
This patch also includes a simple update of other code to current
heimdal, as well as changes we need for better PAC verification.
On the PAC side of things we now match windows member servers by
checking the name and authtime on an incoming PAC. Not generating these
right was the cause of the PAC pain, and so now both the main code and
torture test validate this behaviour.
One thing doesn't work with this patch:
- the sealing of RPC pipes with kerberos, Samba -> Samba seems
broken. I'm pretty sure this is related to AES, and the need to break
apart the gss_wrap interface.
Andrew Bartlett
(This used to be commit a3aba57c00)
'MEMORY_WILDCARD' keytab type. (part of this checking is in effect a
merge from lorikeet-heimdal, where I removed this)
This is achieved by correctly using the GSSAPI gsskrb5_acquire_cred()
function, as this allows us to specify the target principal, regardless
of which alias the client may use.
This patch also tries to simplify some principal handling and fixes some
error cases.
Posted to samba-technical, reviewed by metze, and looked over by lha on IRC.
Andrew Bartlett
(This used to be commit 506a7b67ae)
Kerberos CCACHE into the system.
This again allows the use of the system ccache when no username is
specified, and brings more code in common between gensec_krb5 and
gensec_gssapi.
It also has a side-effect that may (or may not) be expected: If there
is a ccache, even if it is not used (perhaps the remote server didn't
want kerberos), it will change the default username.
Andrew Bartlett
(This used to be commit 6202267f6e)
that the logon_time field in the pac must match the authtime field in the ticket we
gave the client in the AS-REP (and thus also the authtime field in the ticket we get
back in the TGS-REQ).
Many thanks to Andrew Bartlett for his patience in showing me the
basic ropes of all this code! This was a joint effort.
(This used to be commit 7bee374b3f)
caused me pain (and covourty warnings).
Simply gensec_gssapi to assume the properties of lorikeet-heimdal,
rather than having #ifdef around critical features. This simplifies
the code rather a lot.
Andrew Bartlett
(This used to be commit 11156f556d)
If we ever get problems with the kerberos code, it should show up as a
different signature in this PAC.
This involved returning more data from the pac functions, so changed
some callers and split up some functions.
Andrew Bartlett
(This used to be commit d514a74912)
now push/pull a sample PAC, and still have the same byte buffer.
(Metze set up the string code, and probably already has a similar
patch).
Unfortunetly win2k3 still doesn't like what we provide, but every step helps.
Also use data_blob_const() when we are just wrapping data for API
reasons.
Andrew Bartlett
(This used to be commit e7c8076fc1)
(I have included the krbtgt key from my test network).
It turns out the krbtgt signature is over the 16 (or whatever,
enc-type dependent) bytes of the signature, not the entire structure.
Also do not even try to use Kerberos or GSSAPI on an IP address, it
will only fail.

(This used to be commit 2286fad27d)
- move to handmodified pull/push code for PAC_BUFFER
to get the _ndr_size field and the subcontext size right
- after looking closely to the sample w2k3 PAC in our torture test (and some more in my archive)
I found out that the first uint32 before the netr_SamInfo3 was also a pointer,
(and we passed a NULL pointer there before, so I think that was the reason why the windows clients doesn't want our PAC)
w2k3 uses this for unique pointers:
ptr = ndr->ptr_count * 4;
ptr |= 0x00020000;
ndr->ptr_count;
- do one more pull/push round with the sample PAC
metze
(This used to be commit 0eee179415)
much closer.
This changes PIDL to allow a subcontext to have a pad8 flag, saying to
pad behind to an 8 byte boundary. This is the only way I can explain
the 4 trainling zeros in the signature struct.
Far more importantly, the PAC code is now under self-test, both in
creating/parsing our own PAC, but also a PAC from my win2k3 server.
This required changing auth_anonymous, because I wanted to reuse the
anonymous 'server_info' generation code.
I'm still having trouble with PIDL, particulary as surrounds value(),
but I'll follow up on the list.
Andrew Bartlett
(This used to be commit 50a54bf4e9)
We now generate the PAC, and can verifiy both our own PAC and the PAC
from Win2k3.
This commit adds the PAC generation code, spits out the code to get
the information we need from the NETLOGON server back into a auth/
helper function, and adds a number of glue functions.
In the process of building the PAC generation code, some hints in the
Microsoft PAC specification shed light on other parts of the code, and
the updates to samr.idl and netlogon.idl come from those hints.
Also in this commit:
The Heimdal build package has been split up, so as to only link the
KDC with smbd, not the client utils.
To enable the PAC to be veified with gensec_krb5 (which isn't quite
dead yet), the keyblock has been passed back to the calling layer.
Andrew Bartlett
(This used to be commit e2015671c2)
the 'PAC', required for interopability with Active Directory.
This is still a cludge, as it doesn't handle different encryption
types, but that should be fairly easy to fix (needs PIDL/IDL changes).
Andrew Bartlett

keys appear at the end of the PAC, which I feel is deliberate (it
makes this much easier).
I still can't make it work, but I'm sure we are closer.

'mock GSSAPI'.

support in Heimdal.
This removes the 'ext_keytab' step from my Samba4/WinXP client howto.
In doing this work, I realised that the replay cache in Heimdal is
currently a no-op, so I have removed the calls to it, and therefore
the mutex calls from passdb/secrets.c.
This patch also includes a replacement 'magic' mechanism detection,
that does not issue extra error messages from deep inside the GSSAPI
code.
Andrew Bartlett
(This used to be commit c19d5706f4)
- if you want kerberos now, you need to unpack a lorikeet heimdal
tree in source/heimdal/. If source/heimdal/ does not exist at
configure time then all kerberos features are disabled. You cannot
use an external kerberos library for now. That may change later.
- moved lib/replace/ config stuff to lib/replace/ and create a
lib/replace/replace.h. That allows the heimdal build to use our
portability layer, and prevenets duplicate definitions of functions
like strlcat()
- if you do enable heimdal, then you will need to do 'make
HEIMDAL_EXTERNAL' before you build Samba. That should be fixed once
I explain the problem to jelmer (the problem is the inability to
set a depend without also dragging in the object list of the
dependency. We need this for building the heimdal asn1 compiler and
et compiler.
- disabled all of the m4 checks for external kerberos libraries. I
left them in place in auth/kerberos/, but disabled it in
configure.in
some of the heimdal_build/ code is still very rough, for example I
don't correctly detect the correct awk, flex, bison replacements for
heimdal_build/build_external.sh. I expect to fix that stuff up over
the next few days.
