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 avoids keeping the event context around on a the gensec_security
context structure long term.
In the Samba3 server, the event context we either supply is a NULL
pointer as no server-side modules currently use the event context.

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.

The startup and runtime functions that have no dependencies are moved
into the top level.

This allows us to print much more debugging in this critical situation.

thi ensures we are using the header corresponding to the version of
ldb we're linking against. Otherwise we could use the system ldb for
link and the in-tree one for include

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.

I've examined the code paths involved, and it appears an alternative
fix has been made in the ldap_server/ldap_bind.c code, and there is no
code path that uses this behaviour.
Andrew Bartlett
The practice of returning only NT_STATUS_INVALID_PARAMETER hasn't
helped our users to debug problems effectivly, and so we now return
more errors and try and give a more useful debug message when then
happen.

By setting the event context to use for this operation (only) onto
the krb5_context just before we call that operation, we can try
and emulate the specification of an event context to the actual send_to_kdc()
This eliminates the specification of an event context to many other
cli_credentials calls, and the last use of event_context_find()
Special care is taken to restore the event context in the event of
nesting in the send_to_kdc function.

The spengo code won't set this unless it is allowed to by this
same option, but other callers may need it.

Fixed a bug that affected mismatched negotiation between the GSSAPI
layer and the SASL SSF subsequent negotiation. This caused some ldap
clients to hang when trying to authentication with a Samba LDAP
server. The client thought the connection should be signed, the server
thought it should be in plain text

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

This creates a new interface to the auth subsystem, to allow an
auth_context to be created from the ldb, and then tokenGroups to be
calculated in the same way that the auth subsystem would.
Andrew Bartlett
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.
Andrew Bartlett
The auth context was in the past only for NTLM authentication, but we
need a SAM, an event context and and loadparm context for calculating
the local groups too, so re-use that infrustructure we already have in
place.
However, to avoid problems where we may not have an auth_context (in
torture tests, for example), allow a simpler 'session_info' to be
generated, by passing this via an indirection in gensec and an
generate_session_info() function pointer in the struct auth_context.
In the smb_server (for old-style session setups) we need to change the
async context to a new 'struct sesssetup_context'. This allows us to
use the auth_context in processing the authentication reply .

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.

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

This means it must be accessed via the supplied auth_context in the
GENSEC server, and should remove the hard depenceny of GENSEC on the
auth subsystem and ldb (allowing LDB not to rely on LDB is considered
a good thing, apparently)
Andrew Bartlett
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.
