eeb14fcc94 r20296: If we're going to overwrite krb5.conf
only do it for our primary domain.

61a38bd4b8 r19651: Fix interesting bug with the automatic site coverage in Active Directory:
When having DC-less sites, AD assigns DCs from other sites to that site
that does not have it's own DC. The most reliable way for us to identify
the nearest DC - in that and all other cases - is the closest_dc flag in
the CLDAP reply.

37be6913fe r19249: Attempt to fix a site lookup bug found by Guenther.
- "The problem is, with a fresh system, we don't know our sitename,
therefor we do a stupid DNS query for all DCs. The reply we get is a
round-robin list of all 21 DCs, we just pick the first, contact that
and safe that INET.COM#1C query in the name cache for later use...
What we need to do if we don't yet know our sitename, is to contact to
any DC, get the CLDAP reply to tell us in which site we are, then flush
the namecache and requery DNS including the sitename"

Implement the flushing of the #1C entries for a given NetBIOS name/realm
when looking up the site value.

the ugly krb5 hack when they do.

6fada7a82a r17943: The horror, the horror. Add KDC site support by
writing out a custom krb5.conf file containing
the KDC I need. This may suck.... Needs some
testing :-).

the code to redo the CLDAP query to restrict DC
DNS lookups to the sitename. Jerry, please check
to stop me going insane :-).

c52b3fb89f r17881: Another microstep towards better error reporting: Make get_sorted_dc_list
return NTSTATUS.

If we want to differentiate different name resolution problems we might want
to introduce yet another error class for Samba-internal errors. Things like no
route to host to the WINS server, a DNS server explicitly said host not found
etc might be worth passing up.

Because we can not stash everything into the existing NT_STATUS codes, what
about a Samba-specific error class like NT_STATUS_DOS and NT_STATUS_LDAP?

a7f8c26d24 Change our Domain controller lookup routines to more carefully seperate
DNS names (realms) from NetBIOS domain names.

Until now, we would experience delays as we broadcast lookups for DNS names
onto the local network segments.

Now if DNS comes back negative, we fall straight back to looking up the
short name.

bb0598faf5 Put strcasecmp/strncasecmp on the banned list (except for needed calls
in iconv.c and nsswitch/). Using them means you're not thinking about multibyte at
all and I really want to discourage that.

4b5257b5b0 fix 2 bugs:
1)  don't ask trusted DC's for a list of trusted domains.  This causes
      us to treat non-transitive ones as if they were transitive.  Not
      needed anyways

  2)  Fix dc lookup bug where we would always try to use DNS to resolve
      the DC's for a domain (even if it was a trusted NT4 domain).

ce72beb2b5 Removed strupper/strlower macros that automatically map to strupper_m/strlower_m.
I really want people to think about when they're using multibyte strings.

e359dbcedb * cleanup more DC name resolution issues in check_*domain_security()
* is_trusted_domain() is broken without winbind.  Still working on this.
* get_global_sam_name() should return the workgroup name unless we
  are a standalone server (verified by volker)
* Get_Pwnam() should always fall back to the username (minus domain name)
  even if it is not our workgroup so that TRUSTEDOMAIN\user can logon
  if 'user' exists in the local list of accounts (on domain members w/o
  winbind)

Tested using Samba PDC with trusts (running winbindd) and a Samba 3.0
domain member not running winbindd.

notes: make_user_info_map() is slightly broken now due to the
fact that is_trusted_domain() only works with winbindd.  disabled
checks temporarily until I can sort this out.

f51d769dd3 large change:
*)  consolidates the dc location routines again (dns
    and netbios)  get_dc_list() or get_sorted_dc_list()
    is the authoritative means of locating DC's again.

    (also inludes a flag to get_dc_list() to define
     if this should be a DNS only lookup or not)

    (however, if you set "name resolve order = hosts wins"
     you could still get DNS queries for domain name IFF
     ldap_domain2hostlist() fails.  The answer?  Fix your DNS
     setup)

*)  enabled DOMAIN<0x1c> lookups to be funneled through
    resolve_hosts resulting in a call to ldap_domain2hostlist()
    if lp_security() == SEC_ADS

*)  enables name cache for winbind ADS backend

*)  enable the negative connection cache for winbind
    ADS backend

*)  removes some old dead code

*)  consolidates some duplicate code

*)  moves the internal_name_resolve() to use an IP/port pair
    to deal with SRV RR dns replies.  The namecache code
    also supports the IP:port syntax now as well.

*)  removes 'ads server' and moves the functionality back
    into 'password server' (which can support "hostname:port"
    syntax now but works fine with defaults depending on
    the value of lp_security())

f36c96d59c * s/get_dc_name/rpc_dc_name/g (revert a previous change)
* move back to qsort() for sorting IP address in get_dc_list()

* remove dc_name_cache in cm_get_dc_name() since it slowed
  things down more than it helped.  I've made a note of where
  to add in the negative connection cache in the ads code.
  Will come back to that.

* fix rpcclient to use PRINTER_ALL_ACCESS for set printer (instead
  of MAX_ALLOWED)

* only enumerate domain local groups in our domain

* simplify ldap search for seqnum in winbindd's rpc backend

in 3.0 but this is what we have for the moment.
