2010-08-14s3:auth Make Samba3 use the new common struct auth_usersupplied_infoAndrew Bartlett1-2/+1
This common structure will make it much easier to produce an auth module for s3compat that calls Samba4's auth subsystem. In order the make the link work properly (and not map twice), we mark both that we did try and map the user, as well as if we changed the user during the mapping.

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)

2002-01-20This is another *BIG* change...Andrew Bartlett1-3/+1
Samba now features a pluggable passdb interface, along the same lines as the one in use in the auth subsystem. In this case, only one backend may be active at a time by the 'normal' interface, and only one backend per passdb_context is permitted outside that. This pluggable interface is designed to allow any number of passdb backends to be compiled in, with the selection at runtime. The 'passdb backend' paramater has been created (and documented!) to support this. As such, configure has been modfied to allow (for example) --with-ldap and the old smbpasswd to be selected at the same time. This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua. These two backends accept 'non unix accounts', where the user does *not* exist in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to avoid conflicts in the algroitmic mapping of RIDs, they use the values specified in the 'non unix account range' paramter - in the same way as the winbind ranges are specifed. While I was at it, I cleaned up some of the code in pdb_tdb (code copied directly from smbpasswd and not really considered properly). Most of this was to do with % macro expansion on stored data. It isn't easy to get the macros into the tdb, and the first password change will 'expand' them. tdbsam needs to use a similar system to pdb_ldap in this regard. This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I don't have the test facilities for these. I plan to incoroprate at least pdb_ldap into this scheme after consultation with Jerry. Each (converted) passdb module now no longer has any 'static' variables, and only exports 1 init function outside its .c file. The non-unix-account support in this patch has been proven! It is now possible to join a win2k machine to a Samba PDC without an account in /etc/passwd! Other changes: Minor interface adjustments: pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*. pdb_update_sam_account() no longer takes the 'override' argument that was being ignored so often (every other passdb backend). Extra checks have been added in some places. Minor code changes: smbpasswd no longer attempts to initialise the passdb at startup, this is now done on first use. pdbedit has lost some of its 'machine account' logic, as this behaviour is now controlled by the passdb subsystem directly. The samr subsystem no longer calls 'local password change', but does the pdb interactions directly. This allow the ACB_ flags specifed to be transferred direct to the backend, without interference. Doco: I've updated the doco to reflect some of the changes, and removed some paramters no longer applicable to HEAD. (This used to be commit ff354c99c585068af6dc1ff35a1f109a806b326b)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-1/+1
Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps them around for a long time - often past the next call... This adds a getpwnam_alloc and a getpwuid_alloc to the collection. These function as expected, returning a malloced structure that can be free()ed with passwd_free(&passwd). This patch also cuts down on the number of calls to getpwnam - mostly by taking advantage of the fact that the passdb interface is already case-insensiteve. With this patch most of the recursive cases have been removed (that I know of) and the problems are reduced further by not using the sys_ interface in the new code. This means that pointers to the cache won't be affected. (This is a tempoary HACK, I intend to kill the password cache entirly). The only change I'm a little worried about is the change to rpc_server/srv_samr_nt.c for private groups. In this case we are getting groups from the new group mapping DB. Do we still need to check for private groups? I've toned down the check to a case sensitve match with the new code, but we might be able to kill it entirly. I've also added a make_modifyable_passwd() function, that copies a passwd struct into the form that the old sys_getpw* code provided. As far as I can tell this is only actually used in the pass_check.c crazies, where I moved the final 'special case' for shadow passwords (out of _Get_Pwnam()). The matching case for getpwent() is dealt with already, in lib/util_getent.c Also included in here is a small change to register the [homes] share at vuid creation rather than just in one varient of the session setup. (This picks up the SPNEGO cases). The home directory is now stored on the vuid, and I am hoping this might provide a saner way to do %H substitions. TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change the remaining sys_getpwnam() callers to use getpwnam_alloc() and move Get_Pwnam to return an allocated struct. Andrew Bartlett (This used to be commit 1d86c7f94230bc53daebd4d2cd829da6292e05da)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-4/+6
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 Bartlett1-1/+2
- 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)

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-1/+14
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.

2001-11-01Various post AuthRewrite cleanups, fixups and tidyups.Andrew Bartlett1-2/+4
Zero out some of the plaintext passwords for paranoia Fix up some of the other passdb backends with the change to *uid_t rather than uid_t. Make some of the code in srv_netlog_nt.c clearer, is passing an array around, so pass its lenght in is definition, not as a seperate paramater. Use sizeof() rather than magic numbers, it makes things easier to read. Cope with a PAM authenticated user who is not in /etc/passwd - currently by saying NO_SUCH_USER, but this can change in future. Andrew Bartlett (This used to be commit 514c91b16baca639bb04638042bf9894d881172a)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-6/+11
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 3 of 4.Andrew Bartlett1-1/+1
In particular this commit focuses on: Changing the Get_Pwnam code so that it can work in a const-enforced environment. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes allow for 'const' in 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 used to be commit e7634f81c5116ff4addfb7e495f54b6bb78e8f77)

2001-09-29Fix up a number of intertwined issues:Andrew Bartlett1-8/+24
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.

2001-09-19Remove the ugly hacks to get around the Get_Pwnam() calls in pass_check.c byAndrew Bartlett1-4/+10
simply not doing Get_Pwnam() calls in pass_check.c We now make *one* sys_getpnam() call in cgi.c and we always call PAM no matter what it returns. We also no longer run the password cracker for these logins. The truly parinod will note the slight difference in call paths, in that we only call crypt for valid password structs (if not --with-pam). The truly parinoid don't run SWAT either, so I don't think this is an issue. Andrew Bartlett (This used to be commit 9020d884935243f28c19cedc88f076f0709e12cb)
2001-09-12Some patches to authentication:Tim Potter1-2/+4

2001-08-12This patch does a number of things, mostly smaller than they look :-)Andrew Bartlett1-0/+85
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)
