61bd609574 r12060: Work towards allowing the credentials system to allow/deny certain
GENSEC mechansims.  This will allow a machine join to an NT4 domain to
avoid even trying kerberos, or a sensitive operation to require it.

2817ef9f53 r11219: Now that we have the credentials hooked in here, we have a much more

b0fe5e6ade r11196: Clean up memory leaks (pointed out by vl), and handle the case where
the client doesn't guess correctly on the mech to use.  It must back
off and try the mech the server selected from the list.

I'm not particularly attached to our SPNEGO parser, so while I can't
easily use the SPNEGO application logic in Heimdal, I'm going to look
closely at using the asn1 routines to avoid some pain here.

f281d77824 r10291: The patch optionally (off by default, not available in all cases) allows
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.

5edbeca141 r10153: This patch adds a new parameter to gensec_sig_size(), the size of the
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.

7e36c7e607 r9416: Cleanups inspired by jra's work to migrate Samba4's NTLMSSP code back
into Samba3.

The NTLMSSP sign/seal code now assumes that GENSEC has already checked
to see if SIGN or SEAL should be permitted.  This simplfies the code
ensures that no matter what the mech, the correct code paths have been
set in place.

Also remove duplication caused by the NTLMv2 code's history, and
document why some of the things a bit funny.

In SPNEGO, create a new routine to handle the negTokenInit creation.
We no longer send an OID for a mech we can't start (like kerberos on
the server without a valid trust account).

8a68f96f8c r7827: Add in-memory keytab to Samba4, using the new MEMORY_WILDCARD keytab
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.

5c6dd5e800 r6800: A big GENSEC update:
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.

7cabdeb7ec r6113: Move GENSEC and the kerberos code out of libcli/auth, and into
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
