Now we deal with SIDs in almost all of winbind (a couple of limited exceptions
remain, but I'm looking into them - they use non-winbind structs ATM).
This has particular benifits in returning out-of-domain SIDs for group
membership (Need to look into this a bit more) as well as general code quality.
This also removes much of the complexity from the idmap interface, which now
only deals with mapping IDs, not with SID->domain translations.
Breifly tested, but needs more. Fixes some valgrind-found bugs from my
previous commit.
Winbind cache chagned to using SID strings in some places, as I could not
follow exactly how to save and restore multiple packed sids properly.

variable hack, the feild on the pipe, and the server-side.
It only controlled some enum operations in any case.
This is to try and have less 'magic' environment variables.

This updates the 'winbind' authentication module and winbind's 'PAM' (actually
netlogon) code to allow smbd to cache connections to the DC.
This is particulary relevent when we need mutex locks already - there is no
parallelism to be gained anyway.
The winbind code authenticates the user, and if successful, passes back the
'info3' struct describing the user. smbd then interprets that in exactly the
same way as an 'ntdomain' logon.
Also, add parinoia to winbind about null termination.

the sid->uid and uid->sid conversions.
Remove some duplicate arguments from these funcitons, and update the
request/response structures for this and the 'winbind domain name' feature.
As such 'winbindd_lookup_name' now takes both a domain and username.
(This used to be commit ce1b4d4c309e4a60bec5a53224585bd504264672)
smbd, and also makes it much cleaner inside winbindd.
It is mostly my code, with a few changes and testing performed by Alexander
Bokovoy <a.bokovoy@sam-solutions.net>. ab has tested it in security=domain and
security=ads, but more testing is always appricatiated.
The idea is that we no longer cart around a 'domain\user' string, we keep them
seperate until the last moment - when we push that string into a pwent on onto
the socket.
This removes the need to be constantly parsing that string - the domain prefix
is almost always already provided, (only a couple of functions actually changed
arguments in all this).
Some consequential changes to the RPC client code, to stop it concatonating the
two strings (it now passes them both back as params).
I havn't changed the cache code, however the usernames will no longer have a
double domain prefix in the key string. The actual structures are unchanged
- but the meaning of 'username' in the 'rid' will have changed. (The cache is
invalidated at startup, so on-disk formats are not an issue here).

<a.bokovoy@sam-solutions.net>.
The idea is the domain\username is rather harsh for unix systems - people don't
expect to have to FTP, SSH and (in particular) e-mail with a username like
that.
This 'corrects' that - but is not without its own problems.
As you can see from the changes to files like username.c and wb_client.c (smbd's
winbind client code) a lot of assumptions are made in a lot of places about
lp_winbind_seperator determining a users's status as a domain or local user.
The main change I will shortly be making is to investigate and kill off
winbind_initgroups() - as far as I know it was a workaround for an old bug in
winbind itself (and a bug in RH 5.2) and should no longer be relevent.
I am also going to move to using the 'winbind uid' and 'winbind gid' paramaters
to determine a user/groups's 'local' status, rather than the presence of the
seperator.
As such, this functionality is recommended for servers providing unix services,
but is currently less than optimal for windows clients.
(TODO: remove all references to lp_winbind_seperator() and
lp_winbind_use_default_domain() from smbd)

the list received at startup or we get an out of date list. I thought
there might be some sequence number that is incremented when a trusted
domain is added or removed - perhaps there is but I just haven't found it
yet.
- Renamed get_domain_info() to init_domain_list()
- Made an accessor function to return the list of trusted domains rather
than using a global so we don't have to remember to put a magic init
function
- The getent state can not keep a pointer to a winbind_domain structure as
it may be freed if init_domain_list() is called again so we keep the
domain name instead
(This used to be commit 37216c649a394b449eaaaa6644709eafb3bf37ff)
when they are added or removed on the PDC.
- renamed GETPWNAM_FROM_{UID,USER} constants and functions to GETPW{NAM,UID}
- renamed GETGRNAM_FROM_{GID,GROUP} constants and functions to GETGR{NAM,GID}
- use SIGUSR2 in winbindd for debugging/logging instead of SIGUSR1 in
preparation for moving to smbcontrol type messages (not sure whether to
ditch this altogether or not)
- tidy debugging messages in top level winbind user and group routines
- convert talloc_init() to talloc_init_named()
- make enumerations of the domain list use the same local variable names
(This used to be commit eeb8af9c1a66bfcd80823d7b406acbab79857a16)
this one looks like just another winbind backend, and has the
following properties:
- does -ve and +ve cacheing of all queries
- can be disabled with -n switch to winbindd
- stores all records packed, so even huge domains are not a problem
for a complete cache
- handles the server being down
- uses sequence numbers for all entries
This fixes a lot of problems with winbindd. Serving from cache is now
*very* fast.
(This used to be commit fddb4f4c04473a60a97212c0c8e143d6a4d68380)
now do searches on SID. This allows me to do a true ldap sid_to_name()
function
one one function to go!
(This used to be commit 7d44aa3915bc88fd2b2f8454f190b11677cbb848)
This just splits off the dispinfo call behind a methods structure.
I'll split off a few more functions soon, then we will be ready for
LDAP replacement methods
(This used to be commit 0216b0fca115c903ec31ed21427a83c62077dc95)
be easily added (a one liner) once we know the correct error codes returned
by a W2K DC.
All other winbindd calls should go through a similar transparent caching layer
(and will soon).

(This used to be commit b16bb21d371772816a4331f5011c151be0e083d5)
as one memory leak that has been there for ages!
Changed the way talloc is used in get{pw,gr}nam routines.
(This used to be commit d52cd1854fdff18c223d6dd1eca0e26f1f0bf01b)
per-call basis rather than per-connection.
Had a bit more of a reformatting fest.
Still need to run it through insure and handle downed connections.
(This used to be commit 46fe5a8fb96974e1323bc3e5d94fda74edbeb852)
- implemented some of the sam related connection manager routines
- fill in group id and gecos fields for getpwnam/getpwuid routines
- convert querydispinfo to cm
- getent passwd now works
Now for the group related routines...
(This used to be commit 4f8ea877876e91d4762f22e78aeb1bce4c65f011)
I've wrapped up all the decisions about managing, making and closing
connections into a connection manager in nsswitch/winbindd_cm.c.
It's rather incomplete at the moment - only querying basic user info works
at the moment (i.e finger -m DOMAIN/user) and everything else is broken.
Jeremy, please take a look and I'll start moving across the rest of
winbindd to this new system.
(This used to be commit c369cf5af787ed9c642778d21f162716fbf0620e)
many possible mem leaks, and segfaults fixed.
someone should port this fix to 2.2 also.
(This used to be commit fa8e55b8b465114ce209344965c1ca0333b84db9)
so all the glue functions are prefixed with wb_ to avoid conflicts with
the old rpc_client stuff which is still a dependency of smbd/nmbd.
