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the list received at startup or we get an out of date list.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

smb.conf to get it right.
While wb_client needs its lp_load() for samba dependency reasons, it now uses
the new method both to example and test the new code.
Also add an interface version function, and return the winbind's samba version
string.
In preperation for default domains, its now up to winbindd to reject plaintext
auths that don't have a seperator, but NTLM (CRAP) auths now have two feilds,
hence need parsing.

It adds a 'ping' request, just to check winbind is in fact alive
It also changes winbindd_pam_auth_crap to take usernames and domain seperatly.
(backward incompatible change, needs merge to 2.2, but this is not yet released
code, so no workarounds)
Finally, it adds some debugs and fixes a few memory leaks (uses talloc to do
it).

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 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.

function
one one function to go!

I spent quite a while trying to work out how to make this call
via ldap and failed. I then found that MS servers seem use rpc
for sid_to_name, and it works even when in native mode, I ended
up just implementing it via rpc

also created winbindd_rpc.c which contains the functions that
have been converted to the new structure. There will soon be
a winbindd_ads.c for the ldap backend

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

the currently open connections when winbindd receives a USR1 signal.
Hmm - I've just realised this will conflict with the messaging code
but we don't use that yet.

pam authentication. This allows us to link in less other crap.
Authenticating with a challenge/response doesn't seem to work though - we
always get back NT_STATUS_WRONG_PASSWORD.

Had a bit more of a reformatting fest.
Still need to run it through insure and handle downed connections.

- 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...

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.
