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.

aee896ad98 s4-kdc: don't look at global catalog NCs in the kdc

5717da34b9 s4-kdc: treat a kvno of 255 as unspecified
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

ee7cfcadc6 s4-kdc: default kvno for inter-domain trusts to zero
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

0c78640e67 s4:kdc: fix calculation of the rodc kvno
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.

f681859eb8 s4-lsa Implement kerberos ticket life policy
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.

deed2a935b s4-kdc Rework supported encryption type logic to match Microsoft
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.

d76f11a8bd s4-kdc Fix the realm handling again, this time pay attention to the flags
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.

password attributes, we can now indicate to the kdc code that it
should forward the request to a real DC.

dcb1a0698a s4-kdc Remove special case kerberos restriction in the KDC
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).
