Move our basic password checking code from inside the authentication subsystem into a seperate file - ntlm_check.c. This allows us to call these routines from ntlm_auth. The purpose of this exercise is to allow ntlm_auth (when operating as an NTLMSSP server) to avoid talking to winbind. This should allow for easier debugging. ntlm_auth itself has been reorgainised, so as to share more code between the SPNEGO-wrapped and 'raw' NTLMSSP modes. A new 'client' NTLMSSP mode has been added, for use with a Cyrus-SASL module I am writing (based on vl's work) Andrew Bartlett (This used to be commit 2f196bb31ac83cf7922583063c74a5f679ca5be7)

Refactor our authentication and authentication testing code. The next move will be to remove our password checking code from the SAM authentication backend, and into a file where other parts of samba can use it. The ntlm_auth changes provide for better use of common code. Andrew Bartlett (This used to be commit 0d97b10248347398fbee66767baac0c7adf6889d)

Changes all over the shop, but all towards: - NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... Andrew Bartlett (This used to be commit 57a895aaabacc0c9147344d097d333793b77c947)

2003-01-05Clear up the auth_sam password checking code (the core of our password checkingAndrew Bartlett1-33/+58
routines). In particular, we now better support the NT# in LM feild, and the LMv2 password scheme. (LMv2 is basicly NTLMv2 capped at 24 bytes, slightly more secure, and in the LM feild for compatiblity). Thanks to the Samba-TNG team and Luke Leighton for various descriptions of this algorithm, and to MS for a solution that seems to actually make sense for once :-).

2002-11-15Small auth updates:Andrew Bartlett1-2/+2
- add static remove unnneded prototype - move become_root() to just around pdb calls, so as to make it easier to remove when we kill off this silly idea - Change auth_sam to do 'account before password' rather than 'password before account'. This means that we match Win2k in giving 'account disabled' instead of 'wrong password' if the wrong password to a disabled account is used.

2002-08-20Based orginally by work by Kai, this patch moves our NT_TOKEN generation intoAndrew Bartlett1-3/+3
our authenticaion code - removing some of the duplication from the current code. This also gets us *much* closer to supporting a real SAM backend, becouse the SAM can give us the right info then. This also changes our service.c code, so that we do a VUID (rather than uid) cache on the connection struct, and do full NT ACL/NT_TOKEN checks (or cached equivilant) on every packet, for the same r or rw mode the whole share was open for.

2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-28/+30
The auth_authsupplied_info typedef is now just a plain struct - auth_context, but it has been modified to contain the function pointers to the rest of the auth subsystem's components. (Who needs non-static functions anyway?) In working all this mess out, I fixed a number of memory leaks and moved the entire auth subsystem over to talloc(). Note that the TALLOC_CTX attached to the auth_context can be rather long-lived, it is provided for things that are intended to live as long. (The global_negprot_auth_context lasts the whole life of the smbd). I've also adjusted a few things in auth_domain.c, mainly passing the domain as a paramater to a few functions instead of looking up lp_workgroup(). I'm hopign to make this entire thing a bit more trusted domains (as PDC) freindly in the near future. Other than that, I moved a bit of the code around, hence the rather messy diff.

2002-01-01A farily large commit:Andrew Bartlett1-15/+17
- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c - It hasn't been used by anything else since smbpasswd lost its -j - Add a TALLOC_CTX to the auth subsytem. These are only valid for the length of the calls to the individual modules, if you want a longer context hide it in your private data. Similarly, all returns (like the server_info) should still be malloced. - Move the 'ntdomain' module (security=domain in oldspeak) over to use the new libsmb domain logon code. Also rework much of the code to use some better helper functions for the connection - getting us much better error returns (the new code is NTSTATUS). The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for the LUID feilds is sufficient, or if we should do random LUIDs as per the old code. Similarly, I'll move winbind over to this when I get a chance. This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in rpc_client, at least as far as smbd is concerned. While I've given this a basic rundown, any testing is as always appriciated. Andrew Bartlett (This used to be commit d870edce76ecca259230fbdbdacd0c86793b4837)
2001-11-26A number of things to clean up the auth subsytem a bit...Andrew Bartlett1-1/+36
We now default encrypt passwords = yes We now check plaintext passwords (however aquired) with the 'sam' backend rather than unix, if encrypt passwords = yes. (this kills off the 'local' backed. The sam backend may be renamed in its place) The new 'samstrict' wrapper backend checks that the user's domain is one of our netbios aliases - this ensures that we don't get fallback crazies with security = domain. Similarly, the code in the 'ntdomain' and 'smbserver' backends now checks that the user was not local before contacting the DC. The default ordering has changed, we now check the local stuff first - but becouse of the changes above, we will really only ever contact one auth source.

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-31/+44
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.

2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-75/+153
code. In particular this assists tpot in some of his work, becouse it provides the connection between the authenticaion and the vuid generation. Major Changes: - Fully malloc'ed structures. - Massive rework of the code so that all structures are made and destroyed using malloc and free, rather than hanging around on the stack. - SAM_ACCOUNT unix uids and gids are now pointers to the same, to allow them to be declared 'invalid' without the chance that people might get ROOT by default. - kill off some of the "DOMAIN\user" lookups. These can be readded at a more appropriate place (probably domain_client_validate.c) in the future. They don't belong in session setups. - Massive introduction of DATA_BLOB structures, particularly for passwords. - Use NTLMSSP flags to tell the backend what its getting, rather than magic lenghths. - Fix winbind back up again, but tpot is redoing this soon anyway. - Abstract much of the work in srv_netlog_nt back into auth helper functions. This is a LARGE change, and any assistance is testing it is appriciated. Domain logons are still broken (as far as I can tell) but other functionality seems intact. Needs testing with a wide variety of MS clients. Andrew Bartlett (This used to be commit f70fb819b2f57bd57232b51808345e2319d52f6c)

2001-10-29This commit is number 4 of 4.Andrew Bartlett1-3/+3
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 :-) Andrew Bartlett (This used to be commit c95f5aeb9327347674589ae313b75bee3bf8e317)

2001-09-29Fix up a number of intertwined issues:Andrew Bartlett1-2/+2
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.
