2003-11-22(merge from 3.0)Andrew Bartlett1-3/+9
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)
2003-10-30First round of merging various UUID structures.Jim McDonough1-2/+2
This eliminates RPC_UUID. It creates the following struct: struct uuid { uint32 time_low; uint16 time_mid; uint16 time_hi_and_version; uint8 clock_seq[2]; uint8 node[6]; }; which replaces RPC_UUID and various random struct uuid definitions and a flat version: #define UUID_FLAT_SIZE 16 typedef struct uuid_flat { uint8 info[UUID_FLAT_SIZE]; } UUID_FLAT; which pretty much looks like GUID (which I will start eliminating). I want us to use the FLAT one only on the wire (perhaps in files, too?), and I want it to be obvious to the coder that it is the FLAT version. This leaves a couple of compiler warnings, where GUID isn't completely replaced by FLAT_UUID yet...I'll get to those soon. (This used to be commit 1532b5d2e3c61df232b16394acedf6eac387588b)

2003-01-02BIG patch...Andrew Bartlett1-3/+3
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).

2002-08-20Based orginally by work by Kai, this patch moves our NT_TOKEN generation intoAndrew Bartlett1-16/+19
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.

2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-0/+2
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)
2002-01-09Better explanation message for dmalloc.Martin Pool1-1/+1
Also more insertion of parenthesis to handle struct members called 'free'. You can now get useful dmalloc output, as long as it is compatible with your C library. On RH7.1 it looks like you have to rebuild dmalloc to allow free(0) by default, because something in libcrypt does that. (sigh) (This used to be commit 391cbb690196537c8b6292b42c2e27408cc7e249)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-4/+4
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.

members (such as uid and gid). This way we will be able to keep ourselves from writing out default smb.conf settings when the admin doesn't want to, That part is not done yet. Tested compiles with ldap/tdb/smbpasswd. Tested connection with smbpasswd backend. oh...and smbpasswd doesn'y automatically expire accounts after 21 days from the last password change either now.

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-2/+6
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. Andrew Bartlett (This used to be commit 8d31eae52a9757739711dbb82035a4dfe6b40c99)
2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-13/+5
per-share. I beleive that almost all the things that this could have done on a per-share basis can be done with other tools, like 'force user'. Almost all the user's of this paramater used it as a global anyway... While this is one step at a time, I hope it will allow me to considerably simplfy the make_connection() code, particularly for the user-level security case. This already removes an absolute truckload of extra attempted password lookups on the guest account. Andrew Bartlett (This used to be commit 8e708332eded210c1d1fe0cebca3c9c19f054b71)
2001-11-08Change to guest logon code.Andrew Bartlett1-29/+22
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.

groups obtained via a domain logon are respected in the attached NT_USER_TOKEN. This functionality is only available in HEAD, becosue of the way authenticaion has been abstracted.

2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-41/+35
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 Bartlett1-1/+1
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 Bartlett1-3/+3
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.
