of the gsskrb5_acquire_cred hack.
Add support for delegated credentials into the auth and credentials
subsystem, and specifically into gensec_gssapi.
Add the CIFS NTVFS handler as a consumer of delegated credentials,
when no user/domain/password is specified.

Also use the API function for getting a client from a ticket, rather
than just digging in the structure.

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).

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.

This will probably break in a few configurations, so please let me
know. I'll also work to have a way to inhibit kerberos/ntlmssp, as
this removes -k.

Samba to use the target principal name supplied in the mechTokenMIC of
an SPNEGO negTokenInit.
This isn't a great idea for security reasons, but is how Samba3 behaves,
and allows kerberos to function more often in some environments. It is
only available for CIFS session setups, due to the ordering of the
exchange.

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 e4f2afc34362953f56a026b66ae1aea81e9db104)
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.

'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.

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

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.

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.

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

(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.

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'.
Many thanks to Luke Howard for the work he has done on Heimdal for
XAD, to provide the right API hooks in GSSAPI.
Next step is to verify the signatures, and to build the PAC for the
KDC end.

(This used to be commit 2e82743c98e563e97c5a215d09efa0121854d0f7)
lifetime constraints, and works with the in-memory keytab.
Move initialize_krb5_error_table() into our kerberos startup code,
rather than in the GSSAPI code explitly. (Hmm, we probably don't need
this at all..)

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.

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 63272794c41231b335b73e7ccf349282f295c4d2)
should allow us to ditch the local static storage for OIDs, as well as
fix the build on non-heimdal platforms.
Andrew Bartlett
(This used to be commit a7e2ecfac9aaacd673e3583b62139e4f4e114429)
Finally remove the distinction between 'krb5' and 'ms_krb5'. We now
don't do kerberos stuff twice on failure. The solution to this is
slightly more general than perhaps was really required (as this is a
special case), but it works, and I'm happy with the cleanup I achived
in the process. All modules have been updated to supply a
NULL-terminated list of OIDs.
In that process, SPNEGO code has been generalised, as I realised that
two of the functions should have been identical in behaviour.
Over in the actual modules, I have worked to remove the 'kinit' code
from gensec_krb5, and placed it in kerberos/kerberos_util.c.
The GSSAPI module has been extended to use this, so no longer requires
a manual kinit at the command line. It will soon loose the
requirement for a on-disk keytab too.
The general kerberos code has also been updated to move from
error_message() to our routine which gets the Heimdal error string
(which may be much more useful) when available.
Andrew Bartlett
(This used to be commit 0101728d8e2ed9419eb31fe95047944a718ba135)
This patch allows a suitably patched Heimdal GSSAPI library (detected
in configure) to supply to us the session keys, and further compleats
the gensec_gssapi module. This is tested for CIFS, but fails for LDAP
at this point (that is what I'll work on next).
We currently fill out the 'session info' from the SAM, like
gensec_krb5 does, but both will need to use the PAC extraction
functions in the near future.

auth/gensec and auth/kerberos.
This also pulls the kerberos configure code out of libads (which is
otherwise dead), and into auth/kerberos/kerberos.m4
