2004-03-27Merge from HEAD the SMB signing patch that I developed a couple of weeksAndrew Bartlett1-1/+1
ago. This patch re-adds support for 'optional' SMB signing. It also ensures that we are much more careful about when we enable signing, particularly with on-the-fly smb.conf reloads. The client code will now attempt to use smb signing by default, and disable it if the server doesn't correctly support it.

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-4/+19
- NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

2003-05-12And finally IDMAP in 3_0Simo Sorce1-9/+2
We really need idmap_ldap to have a good solution with ldapsam, porting it from the prvious code is beeing made, the code is really simple to do so I am confident it is not a problem to commit this code in. Not committing it would have been worst. I really would have been able to finish also the group code, maybe we can put it into a followin release after 3.0.0 even if it may be an upgrade problem. The code has been tested and seem to work right, more testing is needed for corner cases. Currently winbind pdc (working only for users and not for groups) is disabled as I was not able to make a complete group code replacement that works somewhat in a week (I have a complete patch, but there are bugs) Simo.

a pstrcpy/fstrcpy or at most a safe_strcpy(). These have the advantage of being compiler-verifiable. Get these out of the way, along with a rewrite of 'get_short_archi' in the spoolss client and server. (This pushes around const string pointers, rather than copied strings).

2003-02-24Merge of server-side authentication changes to 3.0:Andrew Bartlett1-19/+40
- user_ok() and user_in_group() now take a list of groups, instead of looking for the user in the members of all groups. - The 'server_info' returned from the authentication is now kept around - in future we won't copy the sesion key, username etc, we will just referece them directly. - rhosts upgraded to use the SAM if possible, otherwise fake up based on getpwnam(). - auth_util code to deal with groups upgraded to deal with non-winbind domain members again.

2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-0/+2
This time its the pdb_getsampwuid() function - which was only being used by the SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is actually generated at login time, and the other changes here simply move that data around. This also means that (when I check some details) we will be able to use the user session key, even when we are not actually the DC, becouse its one of the components of the info3 struct returned on logon. Andrew Bartlett (This used to be commit 799ac01fe08a338e4e94289f5d6767ebf905c1fa)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-0/+16
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)
2002-01-02Actually enforce the passdb API.Andrew Bartlett1-1/+1
Thou shalt not reference SAM_ACCOUNT members directly - always use pdb_get/pdb_set. This is achived by making the whole of SAM_ACCOUNT have a .private member, where the real members live. This caught a pile of examples, and these have beeen fixed. The pdb_get..() functions are 'const' (have been for some time) and this required a few small changes to constify other functions. I've also added some debugs to the pdb get and set, they can be removed if requested. I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb interface, but I need the flags info to do it properly. The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result. Finally, any and all testing is always appriciated - but the basics seem to work. Andrew Bartlett (This used to be commit d3dd28f6c443187b8d820d5a39c7c5b3be2fa95c)
2001-12-27moving SAM_ACCOUNT to include a bit field for initializedGerald Carter1-8/+8
members (such as uid and gid). This way we will be able to keep ourselves from writing out default smb.conf settings when the admin doesn't want to, That part is not done yet. Tested compiles with ldap/tdb/smbpasswd. Tested connection with smbpasswd backend. oh...and smbpasswd doesn'y automatically expire accounts after 21 days from the last password change either now. Just ifdef'd out that code in build_sam_account(). Will merge updates into 2.2 as they are necessary. jerry (This used to be commit f0d43791157d8f04a13a07d029f203ad4384d317)

and replaced with two functions: void zero_ip(struct in_adder *ip); BOOL is_zero_ip(struct in_addr ip); (This used to be commit 778f5f77a66cda76348a7c6f64cd63afe2bfe077)

2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-5/+6
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 Bartlett1-9/+9
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.

2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-19/+32
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 Bartlett1-2/+2
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)
