We detect this function at configure time, but it currently fails to
operate the way we need - that is, when the principal is not
specified, it gives this error. When the principal is specified we
get 'wrong principal in request' in the GSS acceptor, so for now the
best option is to fall back to the alternate approach.

We may not be able to obtain the full error string, so print what we can get.
This is required when the error is the the GSSAPI layer, not the mechanism.

All the callers allocate ->info3 as a talloc child already.
As regardes the TALLOC_ZERO(), I added this originally out of parinoia
many years ago. We do not consistantly zero session keys in memory,
and for NTLMv2 and Kerberos they are random for each sesssion, so
breaking into smbd far enough to read an old session key isn't a
particularly interesting attack, compared with (say) reading the
keytab or the password database. (NTLM and LM session keys are fixed
derivitives of the passwords however).

Instead, we base our guest calculations on the presence or absense of the
authenticated users group in the token, ensuring that we have only
one canonical source of this important piece of authorization data

These additional measures should help ensure we do not accidentily upgrade
a guest to an authenticated user in the future.

This verifies that for NTLM authenticated connections, named pipe
forwarding works as expected, including the session keys.

Eventually we will have just one end point mapper, but for now we need
to use the source4 one for the AD tests.

This will allow the source3 auth code to call this without needing to
double-parse the SIDs

This is not required any more now that they are the same structure,
and shows the value in having a common structure across the codebase.
In particular, now any additional state that needs to be added to the
auth_session_info will be transparently available across the named
pipe proxy, without a need to modify the mapping layer.

This patch finally has the same structure being used to describe the
authorization data of a user across the whole codebase.
This will allow of our session handling to be accomplished with common code.

This makes auth3_session_info identical to auth_session_info
The logic to convert the info3 to a struct auth_user_info is
essentially moved up the stack from the named pipe proxy in
source3/rpc_server to create_local_token().
Andrew Bartlett
Signed-off-by: Andrew Tridgell <tridge@samba.org>
This ensures that the exact same token is used on both sides of the
pipe, when a full token is passed (ie, source3 to source3, but not yet
source4 to to source3 as the unix info isn't calculated there yet).
If we do not have unix_token, we fall back to the old behaviour and go
via create_local_token(). (However, in this case the security_token
is now overwritten, as it is better to have it match the rest of the
session_info create_local_token() builds).

We need to use this, and not utf8string because we need to
transport NULL pointers correctly.

This allows us not the put all of these elements into the auth3_session_info
if they are only used as inputs to these functions.
Andrew Bartlett
Signed-off-by: Andrew Tridgell <tridge@samba.org>
The long term authorization state needs only the final, negotiated
session key, and not the original LM key that may possibly have been
an input.
The special case of the guest account simply needs both values filled
back in with the zeros to avoid changing behaviour in the cached
server_info.

This will allow a transformation of auth3_session_info into
auth_session_info by substitution.
Andrew Bartlett

This brings this structure one step closer to the struct auth_session_info.
A few SMB_ASSERT calls are added in some key places to ensure that
this pointer is initialised, to make tracing any bugs here easier in
future.
NOTE: Many of the users of this structure should be reviewed, as unix
and NT access checks are mixed in a way that should just be done using
the NT ACL. This patch has not changed this behaviour however.

This seperation between the structure used inside the auth modules and
in the wider codebase allows for a gradual migration from struct
auth_serversupplied_info -> struct auth_session_info (from auth.idl)
The idea here is that we keep a clear seperation between the structure
before and after the local groups, local user lookup and the session
key modifications have been processed, as the lack of this seperation
has caused issues in the past.

This will allow a gradual conversion of the required elements from the
current struct auth_serversupplied_info.
This commit adds the structure definition and some helper functions to
copy between the two structures.
At this stage these structures and functions are IDENTICAL to the
existing code, and so show the past history of that code. The plan is
to slowly modify them over the course of the patch series, so that the
changes being made a clear.
By using a seperate structure to auth_serversupplied_info we can
remove elements that are not needed after the authentication, and we
can choose a layout that best reflects the needs of runtime users,
rather than the internals of the authentication subsystem.
By eventually using the auth_session_info from auth.idl, we will gain
a single session authorization structure across the whole codebase,
allowing more code to be shared, and a much more transparent process
for forwarding authorization credentials over the named pipe proxy.
