There was some confusion over dynamically allocated lists of pointers
(i.e you have to make space for the list of pointers and what they are
pointing too) in the memory buffer passed in from libc.
Valgrind is much happer now and as a bonus there is no segfault.
*) 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())
This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
when looking up the WINS server address.
Please *don't* use lp_wins_server() any more!
The wins_srv_ip() function has the following features:
- If the WINS server was entered as a DNS name then the translation to an
IP address will already have taken place. We used to do this every time
a call to the WINS server was made. Ick.
- The return value of wins_srv_ip() is a struct in_addr. Ready to go.
- When WINS failover is fully implemented, you'll be able to enter a colon-
separated list of WINS servers via the WINS SERVER parameter. Using
lp_wins_server() directly will fail if this syntax is used.

string), the wins_srv module now hands back a struct in_addr when it's
called. It caches the IP address once it has been looked up. The IP
is cleared (and must be looked up again) if the 'wins server' parameter
is reread, or if the node is marked 'dead'. A dead node will not be
re-tried for 10 minutes (per a #define in wins_srv.c).
As it was, the code was reading the WINS server name or IP directly from
lp_wins_server. That's okay, except that if the value was expressed as
a name, then a DNS lookup would be done every time the client wanted to
talk to the server.
I still need to work out the implications of failover regarding the
'unicast subnet' list.
Chris -)-----
*Note: failover doesn't actually work yet!* It's just that the code I'm
adding provides all of the pieces necessary.
I do have one big question. Something that I'll have to ask Jeremy, I'm
thinkin'. In nmbd/nmbd_subnetdb.c the IP of the WINS server is used to
set up the Unicast subnet.
...so what happens if the WINS server changes?
My guess is either:
a) nothing.
b) I'd have to change the unicast subnet entry whenever the WINS server
changes.
Urq.
BTW, the lp_wins_server() function no longer returns the WINS server name
or IP. It returns the list of WINS servers entered in smb.conf. To get
the currently 'live' WINS server, use the wins_srv() function.
Fun, eh?

in a /etc/nsswitch.conf hosts line.
Only tested on RH6.1, but should work on a broad range of Linux
distributions. It could probably be made to work with Solaris pretty
easily.
It does not build by default. Build it with "make nsswitch"
