This will allow us to detect from the smb.conf if this is a Samba4 AD
DC which will allow smarter handling of (for example) accidentially
starting smbd rather than samba.
To cope with upgrades from existing Samba4 installs, 'domain
controller' is a synonym of 'active directory domain controller' and
new parameters 'classic primary domain controller' and 'classic backup
domain controller' are added.

This was used in only 2 places, db-glue.c and the lsa server.
In db-glue.c it is awkward though, as it forces to use an unconvenient lsa
structure and conversions from time_t to nt_time only to have nt_times
converted back to time_t for actual use. This is silly.
Also the kdc-policy file was a single funciton library, that's just ridiculous.
The loadparm helper is all we need to keep the values consistent, and if we
ever end up doing something with group policies we will care about it when it's
the time. the code would have to change quite a lot anyway.

kerberos_enctype_to_bitmap is not used anywhere else, so just move it there and
make it static, one less dependency to worry about.

Here we can fetch the right key, and check if the PAC is likely to be signed by a key that
we know. We cannot check the KDC signature on incoming trusts.

This will help users who are used to the kadmin interface, and could
be extended to import existing MIT or Heimdal keys into a Samba4 AD
domain.
To use, add to your krb5.conf
[kdc]
database = {
dbname = samba4:
}
or
[kdc]
database = {
dbname = samba4:/usr/local/samba/etc/smb.conf
}
And copy hdb_samba4.so from PREFIX/modules/hdb to your Heimdal lib directory

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 sorts out the correct handling for the 'kvno=255'
problem. Windows will use the previous trust password for 1 hour after
a password set, and indicates that the previous password is being used
by sending current_kvno-1. That maps to 255 if the trust password has
not actually been changed, so the initial trust password is being
used.

the kdc should not be looking for users in GC partial replicas, as
these users do not have all of the attributes needed for the KDC to
operate
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
windows sometimes sends us a kvno of 255 for inter-domain trusts. We
don't yet know why it does this, but it seems that we need to treat
this as an unspecified kvno
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
the kdc doesn't want to find users who are in partialReplica
partitions, as they won't have the needed secret info for the kdc to
operate. We need to generate referrals instead
Pair-Programmed-With: Andrew Bartlett <abartlet@samba.org>
the exact value doesn't matter, as both Samba and windows check
against the latest password, but the old default of -1 caused ASN.1
parsing errors on windows, which prevented it answering TGS requests
thanks to Hongwei Sun for finding this from a ttt trace

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.

Windows seems to always canonicalize the principal in TGS replies.

As mit_samba_update_pac_data() doesn't support adding
S4U_DELEGATION_INFO to the pac (and I have no clue how to add that)
we should disable S4U2Proxy until this is implemented.

The two error tables need to be combined, but for now seperate the names.
(As the common parts of the tree now use the _common function,
errmap_unix.c must be included in the s3 autoconf build).

The iface_count, iface_n_bcast, and load_interfaces functions
conflicted with functions of the same name in source3, so the source4
functions were renamed. Hopefully we can actually wrap one around the
other in future.

By having kdc_tcp_proxy_send/recv(), which just asks any writeable
dc for a reponse blob, we simplify the interaction between
client-local and local-writeable sockets.
This allows us to make kdc_socket, kdc_process_fn_t, kdc_tcp_call and kdc_tcp_socket
private to kdc.c again.

Bit shifting is non-trivial in C:-)
This
int32_t a = 0x12340000;
uint32_t b = (a >> 16);
results in 0x00001234, but this
int32_t a = 0xEDCB0000;
uint32_t b = (a >> 16);
results in 0xFFFFEDCB, while we expected 0x0000EDCB.

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.

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.
