This fixes up connections to Windows 2003, because the previous import

- Shadowed variables
- "const" related warnings
- Parameter names which shadow function declarations
- Non-void functions which have no return value
(patch also ported upstream)
This removes some of the portability changes made to code under
heimdal/
If these are still required, then we will re-add them with code under
heimdal_build/ (so that we can simply 'drop in' future heimdal
releases).
Andrew Bartlett
This also adds a new hdb-glue.c file, to cope with Heimdal's
uncondtional enabling of SQLITE.
(Very reasonable, but not required for Samba4's use).
Andrew Bartlett
This extends the PKINIT code in Heimdal to ask the HDB layer if the
User Principal Name name in the certificate is an alias (perhaps just
by case change) of the name given in the AS-REQ. (This was a TODO in
the Heimdal KDC)
The testsuite is extended to test this behaviour, and the other PKINIT
certficate (using the standard method to specify a principal name in a
certificate) is updated to use a Administrator (not administrator).
(This fixes the kinit test).
Andrew Bartlett
This extends the hdb_keytab code to allow enumeration of all the keys.
The plan is to allow ktutil's copy command to copy from Samba4's
hdb_samba4 into a file-based keytab used in wireshark.
One day, with a few more hacks, we might even make this a loadable
module that can be used directly...
Andrew Bartlett
This includes in particular changes to the KDC to resolve bug 6272,
originally by Matthieu Patou <mat+Informatique.Samba@matws.net>. We
need to sort the AuthorizationData elements to put the PAC first, or
else WinXP breaks when browsed from Win2k8.
Andrew Bartlett
We had previously assumed it was unconditional. Samba3 didn't mind
very much, but Samba4's samba3-like client did, and the behaviour
differed to Win2008 behaviour.
Andrew Bartlett
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).
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
Also including the supporting changes required to pass make test
A number of heimdal functions and constants have changed since we last
imported a tree (for the better, but inconvenient for us).
Andrew Bartlett
Patch from Timur I. Bakeyev sent to samba-technical:
Heimdal requires openpty() presence. FreeBSD has in in standard libc, so
autodetection works, but compilation fails, as declaration of this function is
missing.
This patch adds proper header detection and inclusion for openpty().
smaba4kpasswd will be used to test the kpasswdd componet of the KDC
(which is up until now untested), and rkpty is an expect-like wrapper
we can use to blackbox that utility.
Andrew Bartlett
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.
Andrew Bartlett
This reverts commit 6a8b07c395.
This isn't strictly needed and will come back in the next merge
from heimdal's trunk.

These changes add a krb5_data parameter named e_data to the windc_plugin to
allow the samba KDC to return extended error information in addition to the
standard KRB5KDC_ERR_* codes. Windows uses the extended information to provide
detailed information in user dialogs (e.g. account disabled, logon hours
restriction, must change password, etc.).

(This used to be commit 0a52e11a9c)
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.
Andrew Bartlett
(This used to be commit 4826f17351)
These principals do not need to be in the same realm as the rest of

caused the RPC-SECRETS test to crash smbd in an inlined version of
this memcmp() call. This patch should have absolutely no effect at
all, but in fact it prevents the crash.
Disassembling at the point of the crash, it shows that gcc is inlining
the memcmp(). I don't know enough MIPS assembler to actually spot the
bug. In case anyone reading this does know MIPS assembler, here is the
gcc generated code that crashes:

This is better than just ignoring the checksum, if it isn't the GSSAPI
checksum. (Samba4 clients in Samba3 mode use more than just the MD5
checksum, and will use a signed AES checksum if available. Actual
samba3 may well do the same in future, against a suitable KDC).
Also a change for easier debugging of checksum issues.
Andrew Bartlett
(This used to be commit 120374f5f9)
This includes many useful upstream changes, many of which should
reduce warnings in our compile.
It also includes a change to the HDB interface, which removes the need

We do need the gsskrb5_get_initiator_subkey() routine. But we should

Andrew Bartlett
(This used to be commit 849500d1aa)
gsskrb5_get_initiator_subkey() routine is bougs. We can indeed use
gss_krb5_get_subkey().
This is fortunate, as there was a segfault bug in 'initiator' version.
Andrew Bartlett
(This used to be commit ec11870ca1)
This merges Samba4 up to current lorikeet-heimdal, which includes a
replacement for some Samba-specific hacks.
In particular, the credentials system now supplies GSS client and
server credentials. These are imported into GSS with
gss_krb5_import_creds(). Unfortunetly this can't take an MEMORY
keytab, so we now create a FILE based keytab as provision and join
time.
Because the keytab is now created in advance, we don't spend .4s at
negprot doing sha1 s2k calls. Also, because the keytab is read in
real time, any change in the server key will be correctly picked up by
the the krb5 code.
To mark entries in the secrets which should be exported to a keytab,
there is a new kerberosSecret objectClass. The new routine
cli_credentials_update_all_keytabs() searches for these, and updates
the keytabs.
This is called in the provision.js via the ejs wrapper
credentials_update_all_keytabs().
We can now (in theory) use a system-provided /etc/krb5.keytab, if
krb5Keytab: FILE:/etc/krb5.keytab
is added to the secrets.ldb record. By default the attribute
privateKeytab: secrets.keytab
is set, pointing to allow the whole private directory to be moved
without breaking the internal links.
(This used to be commit 6b75573df4)
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.
Andrew Bartlett
(This used to be commit 328fa186f2)
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.

credentials to will not have other interfaces, unassoicated with their

DCE_STYLE modified version, and add parametric options to control

It turns out the only remaining issue is sending delegated credentials
to a windows server, probably due to the bug lha mentions in his blog
(using the wrong key).
If I turn delgation on in smbclient, but off in smbd, I can proxy a
cifs session.
I can't wait till Heimdal 0.8, so I'll see if I can figure out the fix
myself :-)

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

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)
data to be signed/sealed. We can use this to split the data from the
signature portion of the resultant wrapped packet.
This required merging the gsskrb5_wrap_size patch from
lorikeet-heimdal, and fixes AES encrption issues on DCE/RPC (we no
longer use a static 45 byte value).
This fixes one of the krb5 issues in my list.
Andrew Bartlett
(This used to be commit e4f2afc343)
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.
