8557c692f6 s4-kdc: Improve grammer and clarity of password change failure messages.
This can still be improved further, but avoid mentioning reasons that
clearly do not apply in this case.

b8815dc23d lib/param: Create a seperate server role for "active directory domain controller"
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.

4b29cf5f66 Move kdc_get_policy helper in the lsa server where it belongs.
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.

12ce07e53b s4-kdc: Add hdb plugin for samba4, to allow kadmin to work
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

e7d5f0a357 gensec: move event context from gensec_*_init() to gensec_update()

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.

0ef8dca9fb s4-kdc: fixed handling of previous vs current trust password
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.

35b309fa0c gensec: clarify memory ownership for gensec_session_info() and gensec_session_key()
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.
