e7634f81c5 This commit is number 3 of 4.
In particular this commit focuses on:

Changing the Get_Pwnam code so that it can work in a const-enforced
environment.

While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.

----

These changes allow for 'const' in the Samba tree.

There are a number of good reasons to do this:

	- I want to allow the SAM_ACCOUNT structure to move from wasteful
	pstrings and fstrings to  allocated strings.  We can't do that if
	people are modifying these outputs, as they may well make
	assumptions about getting pstrings and fstrings

	- I want --with-pam_smbpass to compile with a slightly sane
	volume of warnings, currently its  pretty bad, even in 2.2
	where is compiles at all.

	- Tridge assures me that he no longer opposes 'const religion'
	based on the ability to  #define const the problem away.

	- Changed Get_Pwnam(x,y) into two variants (so that the const
	parameter can work correctly): - Get_Pwnam(const x) and
	Get_Pwnam_Modify(x).

	- Reworked smbd/chgpasswd.c to work with these mods, passing
	around a 'struct passwd' rather  than the modified username

762c8758a7 Fix up a number of intertwined issues:
The big one is a global change to allow us to NULLify the free'ed pointer to a
former passdb object.  This was done to allow idra's SAFE_FREE() macro to do
its magic, and to satisfy the input test in pdb_init_sam() for a NULL pointer
to start with.

This NULL pointer test was what was breaking the adding of accounts up until
now, and this code has been reworked to avoid duplicating work - I hope this
will avoid a similar mess-up in future.

Finally, I fixed a few nasty bugs where the pdb_ fuctions's return codes were
being ignored.  Some of these functions malloc() and are permitted to fail.
Also, this caught a nasty bug where pdb_set_lanman_password(sam, NULL) acheived
precisely didilly-squat, just returning False.  Now that we check the returns
this bug was spotted.  This could allow different LM and NT passwords.

 - the pdbedit code needs to start checking these too, but I havn't had a
chance to fix it.

I have also fixed up where some of the password changing code was using the
pdb_set functions to store *internal* data.  I assume this is from a previous
lot of mass conversion work...

Most likally (and going on past experience) I have missed somthing, probably in
the LanMan password change code which I havn't yet been able to test, but this
lot is in much better shape than it was before.

If all this is too much to swallow (particularly for 2.2.2) then just adding a
sam_pass = NULL to the particular line of passdb.c should do the trick for the
ovbious bug.

2c2317c56e Move pass_check.c over to NTSTATUS, allowing full NTSTATUS from PAM to wire!
Add the ability for swat to run in non-root-mode (ie non-root from inetd).
 - we still need some of the am_root() calls fixed however.

9020d88493 Remove the ugly hacks to get around the Get_Pwnam() calls in pass_check.c by
simply not doing Get_Pwnam() calls in pass_check.c

We now make *one* sys_getpnam() call in cgi.c and we always call PAM no matter
what it returns.  We also no longer run the password cracker for these logins.

The truly parinod will note the slight difference in call paths, in that we only
call crypt for valid password structs (if not --with-pam).  The truly parinoid
don't run SWAT either, so I don't think this is an issue.

d34fd8ec07 Some patches to authentication:
- the usersupplied_info now contains a smb_username (as it comes across on
   the wire) and a unix_username (after being passed through mapping
   functions)

 - when doing security={server,domain} use the smb_username, otherwise use
   the unix_username

dcd6e735f7 the next stage in the NTSTATUS/WERROR change. smbd and nmbd now compile, but the client code still needs some work -

ea1c547ac8 This patch does a number of things, mostly smaller than they look :-)
In particuar, it moves the domain_client_validate stuff out of
auth_domain.c to somwhere where they (I hope) they can be shared
with winbind better.  (This may need some work)

The main purpose of this patch was however to improve some of the
internal documentation and to correctly place become_root()/unbecome_root()
calls within the code.

Finally this patch moves some more of auth.c into other files, auth_unix.c
in this case.
