Allow ticket requests with only a netbios name to be considered 'null'
addresses, and therefore allowed by default.
Use the netbios address as the workstation name for the allowed
workstations check with krb5.

how to test this, can you have a look and see if it works for you? Is
there some hidden switch to kinit to use tcp?
(This used to be commit 0a797712fb)
This patch changes the way lsb_search is called and the meaning of the returned integer.
The last argument of ldb_search is changed from struct ldb_message to struct ldb_result
which contains a pointer to a struct ldb_message list and a count of the number of messages.
The return is not the count of messages anymore but instead it is an ldb error value.
I tryed to keep the patch as tiny as possible bu as you can guess I had to change a good
amount of places. I also tried to double check all my changes being sure that the calling
functions would still behave as before. But this patch is big enough that I fear some bug
may have been introduced anyway even if it passes the test suite. So if you are currently
working on any file being touched please give it a deep look and blame me for any error.
Simo.
(This used to be commit 22c8c97e6f)
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.
Andrew Bartlett
(This used to be commit 36973b1eef)
the code in auth/auth_sam.c for consistancy. This will also allow us
to have one place for a backend directory hook.
I will use a very similar hook to add the PAC.
Andrew Bartlett
(This used to be commit 4315836cd8)
kdc/hdb-ldb.c to share the routines used for auth/
This will require keeping the attribute list in sync, but I think it
is worth it for the next steps (sharing the server_info generation).
Andrew Bartlett
(This used to be commit da38bcefa7)
The aim here is to restructure the queries to match the queries we do
in auth, then to share the code that does the actual query (at least
for user logins).
Then we can generate the PAC from that shared query, rather than a
seperate query.
Andrew Bartlett
(This used to be commit 4395d087e1)
I'm sure this will not be the final resting place, but it will do for
now.
Use the cracknames code in auth/ for creating a server_info given a
principal name only (should avoid assumtions about spliting a
user@realm principal).
Andrew Bartlett
(This used to be commit c9d5d8e45d)
Add the kpasswd server to our KDC, implementing the 'original' and
Microsoft versions of the protocol.
This works with the Heimdal kpasswd client, but not with MIT, I think
due to ordering issues. It may not be worth the pain to have this
code go via GENSEC, as it is very, very tied to krb5.
This gets us one step closer to joins from Apple, Samba3 and other
similar implementations.
Andrew Bartlett
(This used to be commit ab5dbbe10a)
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.
Andrew Bartlett
(This used to be commit fd7203789a)
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)
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)
Add ldb_dn_string_compose so that you can build a dn starting from a
struct ldb_dn base and a set of parameters to be composed in a format
string with the same syntax of printf
(This used to be commit 31c69d0655)
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)
S390. This is an attempt to avoid the panic we're seeing in the
automatic builds.
The main fixes are:
- assumptions that sizeof(size_t) == sizeof(int), mostly in printf formats
- use of NULL format statements to perform dn searches.
- assumption that sizeof() returns an int
(This used to be commit a58ea6b385)
into krbtgt/DNS.DOMAIN.REALM too
with this a windows client asks for the correct ticket when you try to login
(but it's still not working correct, as some how we mess up the dns host name of the
client and it asks for the wrong service principal)
- fix some compiler wranings
- fix some debug messages

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.

I missed one spot in moving from hdb_ent_type to the
internal-to-hdb-ldb hdb_ldb_ent_type, which results in a
Kerberos: Server has invalid flag set -- krbtgt/....@....
on kinit.
Andrew Bartlett
(This used to be commit 2358e0c0e4)
- 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.
(This used to be commit d4648249b2)
- Remove (some) excess logging
- use samdb_connect() to hook into the right handling for multiple tdb handles
- move the connect to the server startup, rather than per-packet.
- Fix config.mk dependency
Tested with a WinXP domain join.

samba4 build system. It assumes we have source/heimdal/ with a current
lorikeet heimdal tree.
I haven't enabled this, its just an example of one possible approach
to heimdal integration.
(This used to be commit 0835d6a0d9)
fill in the function pointers to handle the logging, and catch all the
kerberos warnings. (Currently at level 3).
To avoid a memory leak, this requries a new function: krb5_freelog(),
which I've added to lorikeet/heimdal.
This also required a revamp to how we handle the krb5_context, so as
to make it easier to handle with talloc destructors.
Andrew Bartlett
(This used to be commit 63272794c4)
Using current lorikeet/heimdal, and with the KDC module enabled (it is
disabled by default), I almost get the KDC to link.
(To enable the KDC for testing, comment out the only line in
smbd/config.m4, and add 'kdc' to the 'server services' line in
smb.conf).
