2001-11-26challange -> challengeTim Potter1-3/+3

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 The following parameters have changed: - use rhosts = This has been replaced by the 'rhosts' authentication method, and can be specified like 'auth methods = guest rhosts' - hosts equiv = This needs both this parameter and an 'auth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