This means that we consider the ccache only as reliable as the least
specified of the inputs we used.
This means that we will regenerate the ccache if any of the inputs change.

We need to be able to give sensible error messages when a kerberos
calls fails. This propogates the kerberos error up the stack to the
caller.

For KERBEROS applications the realm should be upcase (function "lp_realm") but
for DNS ones it should be used lowcase (function "lp_dnsdomain"). This patch
implements the use of both in the right way.
It is much easier to do decryption with wireshark when the keytab is
available for every host in the domain. Running 'net export keytab
<keytab name>' will export the current (as pointed to by the supplied
smb.conf) local Samba4 doamin.
(This uses Heimdal's 'hdb' keytab and then the existing hdb-samba4,
and so has a good chance of keeping working in the long term).

This reworks the notes file to be less stream-of-consciousness and more
task for porting, with a very particular focus on a potential port of
Samba4 to use MIT Kerberos.

A number of heimdal functions and constants have changed since we last
imported a tree (for the better, but inconvenient for us).

This is implemented by means of a message to the KDC, to avoid having
to link most of the KDC into netlogon.

This uses Heimdal's PAC parsing code in the:
- LOCAL-PAC test
- gensec_gssapi server
- KDC (where is was already used, the support code refactored from here)
In addition, the service and KDC checksums are recorded in the struct
auth_serversupplied_info, allowing them to be extracted for validation
across NETLOGON.

Rather than require users of Samba4's headers to have krb5-devel
installed (presumably in their system paths), don't expose the minor
functions which require this by default.

(and friends) from SAMBA_3_2, with some minor tweaks:
- avoid including network headers in replace.h unless absolutely required
- autoconf tests for getaddrinfo() in lib/replace
The heimdal-specific code also no longer looks for these functions anymore.

of KDC behaviour. This should allow PKINIT to be turned on and
managed with reasonable sanity.
This also means that the krb5.conf in the same directory as the
smb.conf will always have priority in Samba4, which I think will be
useful.

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 75fddbbc08)
Remove kerberos_verify.c, as we don't need that code any more.
Replace with code for using the new krb5_rd_req_ctx() borrowed from
Heimdal's accecpt_sec_context.c
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.

Recursive dependencies are now forbidden (the build system
will bail out if there are any).
I've split up auth_sam.c into auth_sam.c and sam.c. Andrew,
please rename sam.c / move its contents to whatever/wherever you think suits
best.

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.
Without this code, we get a different session key compared with
Win2k3, and so kerberised smb signing fails.

This avoids issues in replicated setups, as we will replicate the

the moment).

gsskrb5_get_initiator_subkey() routine is bougs. We can indeed use

structure that is more generic than just 'IP/port'.
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' smb.conf option must be set to the binding string for the
server. eg:
password server = ncacn_np:mypdc
Andrew Bartlett
(This used to be commit 272013438f)
This allows a new password to be written in, and old entries removed
(we keep kvno and kvno-1).
Clean up the code a lot, and add comments on what it is doing...

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.
