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)

2001-07-04The big character set handling changeover!Andrew Tridgell1-3/+3
This commit gets rid of all our old codepage handling and replaces it with iconv. All internal strings in Samba are now in "unix" charset, which may be multi-byte. See internals.doc and my posting to samba-technical for a more complete explanation. (This used to be commit debb471267960e56005a741817ebd227ecfc512a)

2001-05-04Big cleanup of passdb and backends.Jean-François Micouleau1-11/+18

2001-03-09Serious (and I *mean* serious) attempt to fix little/bigendian RPC issues.Jeremy Allison1-6/+6
We were reading the endainness in the RPC header and then never propagating it to the internal parse_structs used to parse the data. Also removed the "align" argument to prs_init as it was *always* set to 4, and if needed can be set differently on a case by case basis. Now ready for AS/U testing when Herb gets it set up :-).

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)

2000-08-04Fixed up the user/group contexts when using authenticated pipes.Jeremy Allison1-1/+12
Added a become_root()/unbecome_root() (push/pop security context) around the initgroups() call to ensure it would succeed. Hmmm - I wonder if this call being done as non-root might explain any "group access" bugs we've had in the past.... Jeremy. (This used to be commit 06a65972e872f37d88b84f22ea714feebd38f6c0)

NT_STATUS_XXX). Removed IS_BITS_xxx macros as they were just reproducing "C" syntax in a more obscure way. Jeremy. (This used to be commit c55bcec817f47d6162466b193d533c877194124a)
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)
2000-07-03Some more sec_ctx changes. Modified some fields in the pipe_structTim Potter1-18/+20
structure so authenticated pipe users can have their unix groups set when become_authenticated_pipe_user() is called. (This used to be commit 55c9bf124dc661df43bfe582ef14b1297aeaf0fa)
2000-06-23Removed save directory argument to become_root() calls. Probably most ofTim Potter1-4/+4
this stuff doesn't need to be done as root anyway. (This used to be commit c3cad0ff6482784f95fd54ba51ee5be2354bb95d)
2000-06-16Simplified server pipe implementation by changing arguments passed downTim Potter1-6/+6
through to the individual pipe api calls. Instead of passing two prs_struct pointers, we now pass the pipes_struct pointer which contains the former information as well as other useful stuff like the vuid. (This used to be commit 96addba216bad2189120d78f5531d5caa6f37880)

2000-05-09the beginnings of a new scheme I've working on to allow an easierAndrew Tridgell1-0/+3
head/tng merge. It goes something like this: - headers from tng get copied over one at a time - the old headers get renamed to *_old.h - server side code that used the old headers gets a #define OLD_NTDOMAIN 1 #undef OLD_NTDOMAIN at the start and end of the code - mkproto.awk recognises these special defines and does magic stuff so that each .c file sees the right headers - we start moving the rpc client libraries from tng to head. if this goes OK then, in theory, we should be able to move the client side rpc code from tng to head without disturbing the existing head server side code. Then when that works we can consider merging the server side. it remains to be seen if this scheme will work. So far I've moved rpc_samr.h and don't seem to have broken anything. Note this this is still a very delicate operation, as at every step of the way I want to keep head fully functional. Please don't take part unless you discuss it with me first.

1999-12-12final part of "first" phase converting over to msrpc daemon architecture.Luke Leighton1-26/+4
done a minimal amout of clean-up in the Makefile, removing unnecessary modules from the link stage. this is not complete, yet, and will involve some changes, for example to smbd, to remove dependencies on the password database API that shouldn't be there. for example, smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa API. this first implementation has minor problems with not reinstantiating the same services as the caller. the "homes" service is a good example. (This used to be commit caa50525220b0d0250fa139367593c2de2c12135)
1999-12-12delineation between smb and msrpc more marked. smbd now constructsLuke Leighton1-281/+422
pdus, and then feeds them over either a "local" function call or a "remote" function call to an msrpc service. the "remote" msrpc daemon, on the other side of a unix socket, then calls the same "local" function that smbd would, if the msrpc service were being run from inside smbd. this allows a transition from local msrpc services (inside the same smbd process) to remote (over a unix socket). removed reference to pipes_struct in msrpc services. all msrpc processing functions take rpcsrv_struct which is a structure containing state info for the msrpc functions to decode and create pdus. created become_vuser() which does everything not related to connection_struct that become_user() does. removed, as best i could, connection_struct dependencies from the nt spoolss printing code. todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific info on a per-connection basis, and if the connection dies then so does the info, and that's a fairly serious problem. had to put pretty much everything that is in user_struct into parse_creds.c to feed unix user info over to the msrpc daemons. why? because it's expensive to do unix password/group database lookups, and it's definitely expensive to do nt user profile lookups, not to mention pretty difficult and if you did either of these it would introduce a complication / unnecessary interdependency. so, send uid/gid/num_groups/gid_t* + SID+num_rids+domain_group_rids* + unix username + nt username + nt domain + user session key etc. this is the MINIMUM info identified so far that's actually implemented. missing bits include the called and calling netbios names etc. (basically, anything that can be loaded into standard_sub() and standard_sub_basic()...)

1999-12-08ABOUT TIME!!!!!!!!Luke Leighton1-1/+5
damn, this one is bad. started, at least two days ago, to add an authentication mechanism to the smbd<->msrpc redirector/relay, such that sufficient unix / nt information could be transferred across the unix socket to do a become_user() on the other side of the socket. it is necessary that the msrpc daemon inherit the same unix and nt credentials as the smbd process from which it was spawned, until such time as the msrpc daemon receives an authentication request of its own, whereupon the msrpc daemon is responsible for authenticating the new credentials and doing yet another become_user() etc sequence.

1999-12-06the first independent msrpc daemon - lsarpcd.Luke Leighton1-13/+107
one horrible cut / paste job from smbd, plus a code split of shared components between the two. the job is not _yet_ complete, as i need to be able to do a become_user() call for security reasons. i picked lsarpcd first because you don't _need_ security on it (microsoft botched so badly on this one, it's not real. at least they fixed this in nt5 with restrictanonymous=0x2). fixing this involves sending the current smb and unix credentials down the unix pipe so that the daemon it eventually goes to can pick them up at the other end. i can't believe this all worked!!!
