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 The following parameters have changed: - use rhosts = This has been replaced by the 'rhosts' authentication method, and can be specified like 'auth methods = guest rhosts' - hosts equiv = This needs both this parameter and an 'auth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

first. Add password expiry and 'must change before first logon' support. - This requires that the passdb be up to the job to supply the info. (This used to be commit 53c1c5091ea4e3ccc294f8b6f132be78c11c431f)

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)

Style, doco and DEBUG() fixes for auth_smbpasswd.c (In particular for the account control call). Andrew Bartlett (This used to be commit 3d91c119420973d7dd1af416a1e26efa113dc626)
2001-08-12This patch does a number of things, mostly smaller than they look :-)Andrew Bartlett1-5/+5
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)
2001-08-03This is my 'Authentication Rewrite' version 1.01, mostly as submitted toAndrew Bartlett1-0/+229
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)
