2007-10-10r15475: Ugly and disgusting patch to fix the username map problem I created byVolker Lendecke1-0/+2
changing the token generation. I *hate* this code! Jerry, you have been looking at this as well, can you double-check that I did not screw it up? Thanks, Volker (This used to be commit 2765c4ff8d44c970db3e075b0a2412662f1936c6)
2007-10-10r13576: This is the beginnings of moving the SAM_ACCOUNT data structureGerald Carter1-1/+1
to make full use of the new talloc() interface. Discussed with Volker and Jeremy. * remove the internal mem_ctx and simply use the talloc() structure as the context. * replace the internal free_fn() with a talloc_destructor() function * remove the unnecessary private nested structure * rename SAM_ACCOUNT to 'struct samu' to indicate the current an upcoming changes. Groups will most likely be replaced with a 'struct samg' in the future. Note that there are now passbd API changes. And for the most part, the wrapper functions remain the same. While this code has been tested on tdb and ldap based Samba PDC's as well as Samba member servers, there are probably still some bugs. The code also needs more testing under valgrind to ensure it's not leaking memory. But it's a start...... (This used to be commit 19b7593972480540283c5bf02c02e5ecd8d2c3f0)

2007-10-10r11573: Adding Andrew Bartlett's patch to make machine accountJeremy Allison1-10/+8
logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes the auth module interface to 2 (from 1). The effect of this is that clients can access resources as a machine account if they set these flags. This is the same as Windows (think of a VPN where the vpn client authenticates itself to a VPN server using machine account credentials - the vpn server checks that the machine password was valid by performing a machine account check with the PDC in the same was as it would a user account check. I may add in a restriction (parameter) to allow this behaviour to be turned off (as it was previously). That may be on by default. Andrew Bartlett please review this change carefully. Jeremy.

2004-04-03Fix most of bug #169.Andrew Bartlett1-22/+2
For a (very) long time, we have had a bug in Samba were an NTLMv2-only PDC would fail, because it converted the password into NTLM format for checking. This patch performs the direct comparison required for interactive logons to function in this situation. It also removes the 'auth flags', which simply where not ever used. Natrually, this plays with the size of structures, so rebuild, rebuild rebuild... Andrew Bartlett (This used to be commit 9598593bcf2d877b1d08cd6a7323ee0bc160d4ba)
2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-3/+4
- 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... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)
2003-07-03This patch takes the work the jerry did for beta2, and generalises it:Andrew Bartlett1-0/+2
- The 'not implmented' checks are now done by all auth modules - the ntdomain/trustdomain/winbind modules are more presise as to what domain names they can and cannot handle - The become_root() calls are now around the winbind pipe opening only, not the entire auth call - The unix username is kept seperate from the NT username, removing the need for 'clean off the domain\' in parse_net.c - All sid->uid translations are now validated with getpwuid() to put a very basic stop to logins with 'half deleted' accounts. Andrew Bartlett (This used to be commit 85f88191b9927cc434645ef4c1eaf5ec0e8af2ec)
2003-05-12And finally IDMAP in 3_0Simo Sorce1-0/+3
We really need idmap_ldap to have a good solution with ldapsam, porting it from the prvious code is beeing made, the code is really simple to do so I am confident it is not a problem to commit this code in. Not committing it would have been worst. I really would have been able to finish also the group code, maybe we can put it into a followin release after 3.0.0 even if it may be an upgrade problem. The code has been tested and seem to work right, more testing is needed for corner cases. Currently winbind pdc (working only for users and not for groups) is disabled as I was not able to make a complete group code replacement that works somewhat in a week (I have a complete patch, but there are bugs) Simo.

2003-01-28Merge from HEAD:Andrew Bartlett1-0/+9
- NTLMSSP over SPENGO (sesssion-setup-and-x) cleanup and code refactor. - also consequential changes to the NTLMSSP and SPNEGO parsing functions - and the client code that uses the same functions - Add ntlm_auth, a NTLMSSP authentication interface for use by applications like Squid and Apache. - also consquential changes to use common code for base64 encode/decode. - Winbind changes to support ntlm_auth (I don't want this program to need to read smb.conf, instead getting all it's details over the pipe). - nmbd changes for fstrcat() instead of fstrcpy().

2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-1/+1
This time its the pdb_getsampwuid() function - which was only being used by the SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is actually generated at login time, and the other changes here simply move that data around. This also means that (when I check some details) we will be able to use the user session key, even when we are not actually the DC, becouse its one of the components of the info3 struct returned on logon. Andrew Bartlett (This used to be commit 799ac01fe08a338e4e94289f5d6767ebf905c1fa)
2002-01-11Back out the crazy notion that the NTLMSSP flags actually mean anything...Andrew Bartlett1-1/+7
Replace this with some flags that *we* define. We can do a mapping later if we actually get some more reliable info about what passwords are actually valid. Andrew Bartlett (This used to be commit 7f7a42c3e4d5798ac87ea16a42e4976c3778a76b)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-13/+21
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 Bartlett1-2/+5
- 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)
2001-11-26challange -> challengeTim Potter1-3/+3
(This used to be commit d6318add27f6bca5be00cbedf2226b642341297a)
2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-6/+48
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.

2001-11-03Added NT_USER_TOKEN into server_info to fix extra groups problem.Jeremy Allison1-3/+2
Got "medieval on our ass" about const warnings (as many as I could :-). Jeremy. (This used to be commit ee5e7ca547eff016818ba5c43b8ea0c9fa69b808)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-31/+22
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 Potter1-0/+5
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)
2001-09-12Some patches to authentication:Tim Potter1-2/+2
- 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 (This used to be commit d34fd8ec0716127c7a68eeb8e77d1ae8cc07b547)
2001-08-12This patch does a number of things, mostly smaller than they look :-)Andrew Bartlett1-2/+2
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. Andrew Bartlett (This used to be commit ea1c547ac880def29f150de2172c95213509350e)
2001-08-03Added include guards...Jeremy Allison1-0/+3
We may need to rename this file smbauth.h, as auth.h is so generic it will probably conflict with system header files on some systems. Jeremy. (This used to be commit dd4a6edd497053f4e393216884d356975efef799)
2001-08-03This is my 'Authentication Rewrite' version 1.01, mostly as submitted toAndrew Bartlett1-0/+95
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 used to be commit b30b6202f31d339b48d51c0d38174cafd1cfcd42)
