This commit is number 4 of 4.
In particular this commit focuses on:
Actually adding the 'const' to the passdb interface, and the flow-on changes.
Also kill off the 'disp_info' stuff, as its no longer used.
While these changes have been mildly tested, and are pretty small, any
assistance in this is appreciated.
----
These changes introduces a large dose of 'const' to 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
---
This finishes this line of commits off, your tree should now compile again :-)

This is another *BIG* change...
Samba now features a pluggable passdb interface, along the same lines as the
one in use in the auth subsystem. In this case, only one backend may be active
at a time by the 'normal' interface, and only one backend per passdb_context is
permitted outside that.
This pluggable interface is designed to allow any number of passdb backends to
be compiled in, with the selection at runtime. The 'passdb backend' paramater
has been created (and documented!) to support this.
As such, configure has been modfied to allow (for example) --with-ldap and the
old smbpasswd to be selected at the same time.
This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua.
These two backends accept 'non unix accounts', where the user does *not* exist
in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to
avoid conflicts in the algroitmic mapping of RIDs, they use the values
specified in the 'non unix account range' paramter - in the same way as the
winbind ranges are specifed.
While I was at it, I cleaned up some of the code in pdb_tdb (code copied
directly from smbpasswd and not really considered properly). Most of this was
to do with % macro expansion on stored data. It isn't easy to get the macros
into the tdb, and the first password change will 'expand' them. tdbsam needs
to use a similar system to pdb_ldap in this regard.
This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I
don't have the test facilities for these. I plan to incoroprate at least
pdb_ldap into this scheme after consultation with Jerry.
Each (converted) passdb module now no longer has any 'static' variables, and
only exports 1 init function outside its .c file.
The non-unix-account support in this patch has been proven! It is now possible
to join a win2k machine to a Samba PDC without an account in /etc/passwd!
Other changes:
Minor interface adjustments:
pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*.
pdb_update_sam_account() no longer takes the 'override' argument that was being
ignored so often (every other passdb backend). Extra checks have been added in
some places.
Minor code changes:
smbpasswd no longer attempts to initialise the passdb at startup, this is
now done on first use.
pdbedit has lost some of its 'machine account' logic, as this behaviour is now
controlled by the passdb subsystem directly.
The samr subsystem no longer calls 'local password change', but does the pdb
interactions directly. This allow the ACB_ flags specifed to be transferred
direct to the backend, without interference.
Doco:
I've updated the doco to reflect some of the changes, and removed some paramters
no longer applicable to HEAD.

This is my 'Authentication Rewrite' version 1.01, mostly as submitted to
samba-technical a few weeks ago.
The idea here is to standardize the checking of user names and passwords,
thereby ensuring that all authtentications pass the same standards. The
interface currently implemented in as
nt_status = check_password(user_info, server_info)
where user_info contains (mostly) the authentication data, and server_info
contains things like the user-id they got, and their resolved user name.
The current ugliness with the way the structures are created will be killed
the next revision, when they will be created and malloced by creator functions.
This patch also includes the first implementation of NTLMv2 in HEAD, but which
needs some more testing. We also add a hack to allow plaintext passwords to be
compared with smbpasswd, not the system password database.
Finally, this patch probably reintroduces the PAM accounts bug we had in
2.2.0, I'll fix that once this hits the tree. (I've just finished testing
it on a wide variety of platforms, so I want to get this patch in).

This is another rather major change to the samba authenticaion
subystem.
The particular aim is to modularized the interface - so that we
can have arbitrary password back-ends.
This code adds one such back-end, a 'winbind' module to authenticate
against the winbind_auth_crap functionality. While fully-functional
this code is mainly useful as a demonstration, because we don't get
back the info3 as we would for direct ntdomain authentication.
This commit introduced the new 'auth methods' parameter, in the
spirit of the 'auth order' discussed on the lists. It is renamed
because not all the methods may be consulted, even if previous
methods fail - they may not have a suitable challenge for example.
Also, we have a 'local' authentication method, for old-style
'unix if plaintext, sam if encrypted' authentication and a
'guest' module to handle guest logins in a single place.
While this current design is not ideal, I feel that it does
provide a better infrastructure than the current design, and can
be built upon.
The following parameters have changed:
- use rhosts =
This has been replaced by the 'rhosts' authentication method,
and can be specified like 'auth methods = guest rhosts'
- hosts equiv =
This needs both this parameter and an 'auth methods' entry
to be effective. (auth methods = guest hostsequiv ....)
- plaintext to smbpasswd =
This is replaced by specifying 'sam' rather than 'local'
in the auth methods.
The security = parameter is unchanged, and now provides defaults
for the 'auth methods' parameter.
The available auth methods are:
guest
rhosts
hostsequiv
sam (passdb direct hash access)
unix (PAM, crypt() etc)
local (the combination of the above, based on encryption)
smbserver (old security=server)
ntdomain (old security=domain)
winbind (use winbind to cache DC connections)
Assistance in testing, or the production of new and interesting
authentication modules is always appreciated.

This is my 'Authentication Rewrite' version 1.01, mostly as submitted to
samba-technical a few weeks ago.
The idea here is to standardize the checking of user names and passwords,
thereby ensuring that all authtentications pass the same standards. The
interface currently implemented in as
nt_status = check_password(user_info, server_info)
where user_info contains (mostly) the authentication data, and server_info
contains things like the user-id they got, and their resolved user name.
The current ugliness with the way the structures are created will be killed
the next revision, when they will be created and malloced by creator functions.
This patch also includes the first implementation of NTLMv2 in HEAD, but which
needs some more testing. We also add a hack to allow plaintext passwords to be
compared with smbpasswd, not the system password database.
Finally, this patch probably reintroduces the PAM accounts bug we had in
2.2.0, I'll fix that once this hits the tree. (I've just finished testing
it on a wide variety of platforms, so I want to get this patch in).
