ldb: One-level search was incorrectly falling back to full DB scan

When no search filter is specified, the code falls back to using
'(|(objectClass=*)(distinguishedName=*)'. ltdb_index_dn() then failed
because matching against '*' is not indexed. The error return then
caused the code to fallback to a full-scan of the DB, which could have a
considerable performance hit.

Instead, we want to continue on and do the ltdb_index_filter() over the
indexed results that were returned.

heimdal: lib/krb5: do not fail set_config_files due to parse error

Follow Apple's lead and do not fail krb5_set_config_files() simply
because one of the files in the profile list fails to parse correctly.
Doing so can lead to hard to find failures and could lead to an end
user shooting themselves in the foot and no longer be able to login
to their system to fix it.

Parse as many of the files as we can.  Only fail krb5_set_config_files()
if init_context_from_config_file() fails.

krb5_wrap: fix keep_old_entries logic for older kerberos libraries

MIT kerberos 1.13 and older only stores 8 bits of the KVNO. The change
from commit 35b2fb4ff32 resulted in breakage for these kerberos
versions: 'net ads keytab create' reads a large KVNO from AD, and only
the lower 8 bits are stored. The next check then removed the entry again
as the 8 bit value did not match the currently valid KVNO.

Fix this by limiting the check to only 8 bits.

auth/ntlmssp: fix handling of GENSEC_FEATURE_LDAP_STYLE as a server

This fixes "NTLMSSP NTLM2 packet check failed due to invalid signature!"
error messages, which were generated if the client only sends
NTLMSSP_NEGOTIATE_SIGN without NTLMSSP_NEGOTIATE_SEAL on an LDAP
connection.

This fixes a regession in the combination of commits
77adac8c3cd2f7419894d18db735782c9646a202 and
3a0b835408a6efa339e8b34333906bfe3aacd6e3.

We need to evaluate GENSEC_FEATURE_LDAP_STYLE at the end
of the authentication (as a server, while we already
do so at the beginning as a client).

As a reminder I introduced GENSEC_FEATURE_LDAP_STYLE
(as an internal flag) in order to let us work as a
Windows using NTLMSSP for LDAP. Even if only signing is
negotiated during the authentication the following PDUs
will still be encrypted if NTLMSSP is used. This is exactly the
same as if the client would have negotiated NTLMSSP_NEGOTIATE_SEAL.
I guess it's a bug in Windows, but we have to reimplement that
bug. Note this only applies to NTLMSSP and only to LDAP!
Signing only works fine for LDAP with Kerberos
or DCERPC and NTLMSSP.

The reason for the TALLOC_FREE(state) was to cleanup the possible

s3:cleanupd: use MSG_SMB_BRL_VALIDATE to signal cleanupd unclean process shutdown

Since 6423ca4bf293cac5e2f84b1a37bb29b06b5c05ed messaging_send_all()
broadcasts messages in a cluster, so cleanupd receives those broadcasts

storm.

Note that MSG_SMB_BRL_VALIDATE was unused only in the sense that noone
*listened* to it, but we were still *sending* the message in
smbd_parent_ctdb_reconfigured(). de6fe2a1dd6ab03b1c369b61da17fded72305b2d

s3: smbd. Generic fix for incorrect reporting of stream dos attributes on a directory

According to MS-FSA a stream name does not have
separate DOS attribute metadata, so we must return
the DOS attribute from the base filename. With one caveat,
a non-default stream name can never be a directory.

As this is common to all streams data stores, we handle
it here instead of inside all stream VFS modules.

Otherwise identical logic would have to be added to
all streams modules in their [f]get_dos_attribute_fn()
VFS calls.
