Patch by emil@disksites.com <Emil Rasamat> to ensure we always always free() each auth method. (We had relied on the use of talloc() only, despite providing the free() callback) Andrew Bartlett (This used to be commit 58c4963a8389dff4d925548217fabed1c9932abd)
2003-11-22(merge from 3.0)Andrew Bartlett1-0/+3
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)

2003-01-13Updates to our NTLMSSP code:Andrew Bartlett1-1/+9
This tries to extract our server-side code out of sessetup.c, and into a more general lib. I hope this is only a temporay resting place - I indend to refactor it again into an auth-subsystem independent lib, using callbacks. Move some of our our NTLMSSP #defines into a new file, and add two that I found in the COMsource docs - we seem to have a double-up, but I've verified from traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real. This code also copes with ASCII clients - not that we will ever see any here, but I hope to use this for HTTP, were we can get them. Win2k authenticates fine under forced ASCII, btw. Tested with Win2k, NTLMv2 and Samba's smbclient. Andrew Bartlett (This used to be commit b6641badcbb2fb3bfec9d00a6466318203ea33e1)
2003-01-02BIG patch...Andrew Bartlett1-2/+2
This patch makes Samba compile cleanly with -Wwrite-strings. - That is, all string literals are marked as 'const'. These strings are always read only, this just marks them as such for passing to other functions. What is most supprising is that I didn't need to change more than a few lines of code (all in 'net', which got a small cleanup of net.h and extern variables). The rest is just adding a lot of 'const'. As far as I can tell, I have not added any new warnings - apart from making all of tdbutil.c's function const (so they warn for adding that const string to struct).

2002-07-31Let everybody enjoy my new toy - make it the default!Andrew Bartlett1-2/+2
Authenticaions will now attempt to use winbind, and only fall back to 'ntdomain' (the old security=domain) code if that fails (for any reason, including wrong password). I'll fix up the authenticaion code to better handle the different types of failures in the near future. Andrew Bartlett (This used to be commit 78f0d4337bd263d26d7b349eaf8148e863c62f69)

2002-03-02Allow Samba to trust NT4 Domains.Andrew Bartlett1-0/+1
This commit builds on the auth subsystem to give Samba support for trusting NT4 domains. It is off by default, but is enabled by adding 'trustdomain' to the 'auth methods' smb.conf paramater. Tested against NT4 only - there are still some issues with the join code for Win2k servers (spnego stuff). The main work TODO involves enumerating the trusted domains (including the RPC calls to match), and getting winbind to run on the PDC correctly. Similarly, work remains on getting NT4 to trust Samba domains. Andrew Bartlett (This used to be commit ac8c24a9a888a3f916e8b40238b936e6ad743ef7)

2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-107/+258
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. Andrew Bartlett (This used to be commit 12f5515f556cf39fea98134fe3e2ac4540501048)
2002-01-01A farily large commit:Andrew Bartlett1-4/+10
- 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)

the method used for checking if a domain is a trusted domain is very crude, we should really call a backend fn of some sort. For now I'm using winbindd to do the dirty work. (This used to be commit adf44a9bd0d997ba4dcfadc564a29149531525af)

2001-11-26A number of things to clean up the auth subsytem a bit...Andrew Bartlett1-1/+1
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. Andrew Bartlett (This used to be commit e89b47f65e7eaf5eb288a3d6ba2d3d115c628e7e)
2001-11-26challange -> challengeTim Potter1-4/+4
(This used to be commit d6318add27f6bca5be00cbedf2226b642341297a)
2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-79/+86
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.

2001-11-08Change to guest logon code.Andrew Bartlett1-24/+43
This changes the way we process guest logons - we now treat them as normal logons, but set the 'guest' flag. In particular this is needed becouse Win2k will do an NTLMSSP login with username "", therefore missing our previous guest connection code - this is getting a pain to do as a special case all over the shop. Tridge: We don't seem to be setting a guest bit for NTLMSSP, in either the anonymous or authenticated case, can you take a look at this? Also some cleanups in the check_password() code that should make some of the debugs clearer. Various other minor cleanups: - change the session code to just take a vuser, rather than having to do a vuid lookup on vuser.vuid - Change some of the global_client_caps linking - Better debug in authorise_login(): show the vuid. Andrew Bartlett (This used to be commit 62f4e4bd0aef9ade653b3f8d575d2864c166ab4d)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-145/+118
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)
2001-10-31Added some extra fields to the auth_serversupplied_info structure.Tim Potter1-1/+13
To obtain the full group membership of a user (i.e nested groups on a win2k native mode server) it is necessary to merge this list of groups with the groups returned by winbindd when creating an nt access token. This breaks winbindd linking while AB and I sync up our changes to the authentication subsystem. (This used to be commit 4eeb7bcd783d7cfb3ac232f1faa035773007401d)

2001-09-29Fix up a number of intertwined issues:Andrew Bartlett1-0/+4
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.
