If we are set to canonicalize, we get back the fixed UPPER
case realm, and the real username (ie matching LDAP
samAccountName)
Otherwise, if we are set to enterprise, we
get back the whole principal as-sent
Finally, if we are not set to canonicalize, we get back the
fixed UPPER case realm, but the as-sent username

Based on a patch by Samuel Cabrero <scabrero@zentyal.com>
This ensures we write the correct (implict, samAccountName) based UPN into
the ticket, rather than the userPrincipalName, which will have a different
realm.

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.

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

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

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

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

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.

We now no longer print tickets with a potentially infinite life, and
we report the same life over LSA as we use in the KDC. We should get
this from group policy, but for now it's parametric smb.conf options.

Thanks to Hongwei Sun for the clear description of the algorithim
involved. Importantly, it isn't possible to remove encryption types
from the list, only to add them over the defaults (DES and
arcfour-hmac-md5, and additional AES for DCs and RODCs).
This changes the behaviour for entries with
msDS-supportedEncryptionTypes: 0, which Angelos Oikonomopoulos
reported finding set by ADUC when attempting to store cleartext
passwords.

The KDC sets different flags for the AS-REQ (this is client-depenent)
and the TGS-REQ to determine if the realm should be forced to the
canonical value. If we do this always, or do this never, we get into
trouble, so it's much better to honour the flags we are given.
Andrew Bartlett
This means that when we are an RODC, and an account does not have the
password attributes, we can now indicate to the kdc code that it
should forward the request to a real DC.
(The proxy code itself is not in this commit).

We should avoid using Kerberos or any other recursive auth mechanism
in ldb backends, but denying Kerberos here won't be enough, so
remove the special case. (Typcially we bind using a different password
space and DIGEST-MD5 or NTLM).
