Unfortunately these functions are not available in MIT and there is no easy
workaround or compat funciton I can see at this stage. Will fix properly once
MIT gets the necessary functions or if another workaround can be found.
Make it clearly a gensec_krb5 accessory file.
This function should never be used anywhere else.
This function was copied out from the Heimdal tree and is kept in a separate
file for clarity and to keep the original license boilerplate.
This makes it simpler to slowly integrate MIT support and also amkes it
somewhat clearer what operation is really requested.
The 24u2 part is really only used by the cifs proxy code so we can temporarily
disable it in the MIT build w/o major consequences.
With waf build include directories are defined by dependencies specified to subsystems.
Without proper dependency <gssapi/gssapi.h> cannot be found for embedded Heimdal builds
when there are no system-wide gssapi/gssapi.h available.
Split out GSSAPI header includes in a separate replacement header and use that explicitly
where needed.

This avoids casting to and from the struct auth_user_info_dc *user_info_dc
to to this, the
if (user_info_dc->info->authenticated)
is moved into auth_generate_session_info_wrapper(), which is the
function that gensec_security->auth_context->generate_session_info
points to.
Andrew Bartlett
gensec_ntlmssp does not need to know the internal form of the
struct user_info_dc or auth_serversupplied_info. This will allow the
calling logic to be put in common.
Andrew Bartlett
These are optional to supply - some callers only provide an auth_context for the
other plugin functions, and so we need to deal with this cleanly.

This makes the dependencies simpler, as this code path is no longer
required. (That is, it makes no sense to have an NTLM login without
an auth context, and the gensec_gssapi and gensec_krb5 modules call
the PAC blob function below instead).
Andrew Bartlett
This demonstrates how a different function pointer can be supplied
to handle the PAC blob, without depending on the provisioned samdb etc.
Andrew Bartlett
This uses a single callback to handle the PAC from the DATA_BLOB
format until it becomes a struct auth_session_info.
This allows a seperation between the GSS acceptor code and the PAC
interpretation code based on the supplied auth context.

This library was tiny - containing just two public functions than were
themselves trivial. The amount of overhead this causes isn't really worth the
benefits of sharing the code with other projects like OpenChange. In addition, this code
isn't really generically useful anyway, as it can only load from the module path
set for Samba at configure time.
Adding a new library was breaking the API/ABI anyway, so OpenChange had to be
updated to cope with the new situation one way or another. I've added a simpler
(compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.

This patch makes sure we start NTLMSSP with the given MechToken,

first. As that would fail the authentication with an error

This will allow gensec_start.c to move to the top level. This does not change
what code uses the cli_credentials code, but allows the gensec code to be
more broadly.
Andrew Bartlett
This is done so that the lpcfg_ functions are available across the whole
build, either with the struct loadparm_context loaded from an smb.conf directly
or as a wrapper around the source3 param code.
This is not the final, merged loadparm, but simply one step to make
it easier to solve other problems while we make our slow progress
on this difficult problem.
Andrew Bartlett
to properly support multi-domain forests we need to determine if an
incoming username is part of a known forest domain or not. To do this
for all possible SPN forms, we need to use CrackNames.
This changes map_user_info() to use CrackNames if a SAM context is
available, and asks the CrackNames services to parse the incoming
username and domain into a NT4 form, which can then be used in the
SAM.

This is slightly less efficient, because we no longer keep a cache on
the gensec structures, but much clearer in terms of memory ownership.
Both gensec_session_info() and gensec_session_key() now take a mem_ctx
and put the result only on that context.
Some duplication of memory in the callers (who were rightly uncertain
about who was the rightful owner of the returned memory) has been
removed to compensate for the internal copy.

It's important that we don't store the tgt for the machine account
in the same krb5_ccache as the ticket for the impersonated principal.
We may pass it to some krb5/gssapi functions and they may use them
in the wrong way, which would grant machine account privileges to
the client.

In a long-lived credentials cache situation, we may need to refetch
the ticket after (say) 10 hours. This code should help that happen,
by checking the lifetime before returning any credentials cache or
GSSAPI credentials.
Andrew Bartlett
This means that we will leave a slew of file based credentials caches
in /tmp, which should give some clues to the administrator or
developer via klist as to what has gone wrong.
Andrew Bartlett
This changes auth_methods_from_lp to no longer use the parametric
options, and to cope with ROLE_DOMAIN_BDC and ROLE_DOMAIN_PDC. This
will assist in calling the source4 auth subsystem with a source3
derived lp_ctx.
Andrew Bartlett
Now that we don't allow the smb.conf to change the modules dir, many
functions that simply load modules or initialise a subsytem that may
load modules no longer need an lp_ctx.
Andrew Bartlett
This also adds a cli_credentials_get_self_service() helper function.
In order to support S4U2Proxy we need to be able to set

This function is problematic because a string may expand in size when

s4 implementation.

This uses the source3 PAC code (originally from Samba4) with some
small changes to restore functionality needed by the torture tests,
and to have a common API.
Andrew Bartlett
This requires a small rework of the build system to ensure that the
correct #define statements are made in both the s3 and top level
builds. We now define the various HAVE_ macros in config.h at all
times, using heimdal_build/wscript_configure when that is in use.

This changes auth_session_info_transport to just be a wrapper, rather

this prevents conflicts with the s3 auth modules. The auth modules in
samba3 may appear in production smb.conf files, so it is preferable to
rename the s4 modules for minimal disruption.

This changes auth_serversupplied_info into the IDL-defined struct
auth_user_info_dc. This then in turn contains a struct
auth_user_info, which is the only part of the structure that is
mainted into the struct session_info.
The idea here is to avoid keeping the incomplete results of the
authentication (such as session keys, lists of SID memberships etc) in
a namespace where it may be confused for the finalised results.

This makes everything reference a server_info->sids list, which is now
a struct dom_sid *, not a struct dom_sid **. This is in keeping with

In the process, I also tidy up the talloc tree (move more structures
under their logical parents) and check for some possible overflows in
situations with a pathological number of sids.
