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 The following parameters have changed: - use rhosts = This has been replaced by the 'rhosts' authentication method, and can be specified like 'auth methods = guest rhosts' - hosts equiv = This needs both this parameter and an 'auth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.

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.

2001-11-04Fix up authenticated pipes in line with vuser changes. This ensures that globalAndrew Bartlett1-1/+4
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. Both vuid logins and authenticated pipes need to use the same code for this in future. Can sombody with the correct facilties check this please?\ Thanks, Andrew Bartlett (This used to be commit caae69fcd096f20aa4c6879b95ec2c275afea041)

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.

they can have general effect. Fixed up workstaion support in the rest of samba, so that we can do these checks. Pass through the workstation for cli_net_logon(), if supplied. (This used to be commit 7f04a139b2ee34b4c282590509cdf21395815a7a)
2001-09-12Some patches to authentication:Tim Potter1-1/+1
- 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)

2001-08-03This is my 'Authentication Rewrite' version 1.01, mostly as submitted toAndrew Bartlett1-5/+13
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)

We were reading the endainness in the RPC header and then never propagating it to the internal parse_structs used to parse the data.

2000-11-13Large commit which restructures the local password storage API.Gerald Carter1-16/+17
Currently the only backend which works is smbpasswd (tdb, LDAP, and NIS+) are broken, but they were somewhat broken before. :) The following functions implement the storage manipulation interface /*The following definitions come from passdb/pdb_smbpasswd.c */ BOOL pdb_setsampwent (BOOL update); void pdb_endsampwent (void); SAM_ACCOUNT* pdb_getsampwent (void); SAM_ACCOUNT* pdb_getsampwnam (char *username); SAM_ACCOUNT* pdb_getsampwuid (uid_t uid); SAM_ACCOUNT* pdb_getsampwrid (uint32 rid); BOOL pdb_add_sam_account (SAM_ACCOUNT *sampass); BOOL pdb_update_sam_account (SAM_ACCOUNT *sampass, BOOL override); BOOL pdb_delete_sam_account (char* username); There is also a host of pdb_set..() and pdb_get..() functions for manipulating SAM_ACCOUNT struct members. Note that the struct passdb_ops {} has gone away. Also notice that struct smb_passwd (formally in smb.h) has been moved to passdb/pdb_smbpasswd.c and is not accessed outisde of static internal functions in this file. All local password searches should make use of the the SAM_ACCOUNT struct and the previously mentioned functions. I'll write some documentation for this later. The next step is to fix the TDB passdb backend, then work on spliting the backends out into share libraries, and finally get the LDAP backend going. What works and may not: o domain logons from Win9x works o domain logons from WinNT 4 works o user and group enumeration as implemented by Tim works o file and print access works o changing password from Win9x & NT ummm...i'll fix this tonight :) If I broke anything else, just yell and I'll fix it. I think it should be fairly quite. -- jerry (This used to be commit 0b92d0838ebdbe24f34f17e313ecbf61a0301389)

2000-07-27Ok - this is a *BIG* change - but it fixes the problems with static stringsJeremy Allison1-7/+23
in the RPC code. This change was prompted by trying to save a long (>256) character comment in the printer properties page. The new system associates a TALLOC_CTX with the pipe struct, and frees the pool on return of a complete PDU. A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx code, and is freed in the main loop. This code works with insure, and seems to be free of memory leaks and crashes (so far) but there are probably the occasional problem with code that uses UNISTRxx structs on the stack and expects them to contain storage without doing a init_unistrXX(). This means that rpcclient will probably be horribly broken. A TALLOC_CTX also needed associating with the struct cli_state also, to make the prs_xx code there work. The main interface change is the addition of a TALLOC_CTX to the prs_init calls - used for dynamic allocation in the prs_XXX calls. Now this is in place it should make dynamic allocation of all RPC memory on unmarshall *much* easier to fix. Jeremy. (This used to be commit 0ff2ce543ee54f7364e6d839db6d06e7ef1edcf4)
