2007-10-10r7217: Only allow schannel connections if a successful Auth2 has been doneVolker Lendecke1-0/+7
before. Things tested: Domain join and subsequent interactive and network logon to NT4, W2kSP and XPSP2 workstations and a NT4 domain trusting us. Right now I've got problems with my W2k3 domain trusts. So this needs testing, although I'm really confident that this does not break.

2007-10-10r6014: rather large change set....Gerald Carter1-0/+7
pulling back all recent rpc changes from trunk into 3.0. I've tested a compile and so don't think I've missed any files. But if so, just mail me and I'll clean backup in a couple of hours. Changes include \winreg, \eventlog, \svcctl, and general parse_misc.c updates. I am planning on bracketing the event code with an #ifdef ENABLE_EVENTLOG until I finish merging Marcin's changes (very soon). (This used to be commit 4e0ac63c36527cd8c52ef720cae17e84f67e7221)

2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-1/+1
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork(). For other systems, we now only re-seed after a fork, and on startup. No need to do it per-operation.

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-3/+9
- 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)

2003-08-14Attempt at fixing bug #283. There however is no solution.Gerald Carter1-60/+135
There is a workaround documented in the bug report. This patch does: * add server support for the LSA_DS UUID on the lsarpc pipe * store a list of context_ids/api_structs in the pipe_struct so that we don't have to lookup the function table for a pipe. We just match the context_id. Note that a dce/rpc alter_context does not destroy the previous context so it is possible to have multiple bindings active on the same pipe. Observed from standalone win2k sp4 client. * added server code for DsROleGetPrimaryDOmainInfo() but disabled it since it causes problems enumerating users and groups from a 2ksp4 domain member in a Samba domain.

2003-07-17In the presense of RPC fragments, schannel is not strictly request/reply,Andrew Bartlett1-5/+0

2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-14/+26
the schannel code, but I've included that anyway. :-) This patch revives the client-side NTLMSSP support for RPC named pipes in Samba, and cleans up the client and server schannel code. The use of the new code is enabled by the 'sign', 'seal' and 'schannel' commands in rpcclient. The aim was to prove that our separate NTLMSSP client library actually implements NTLMSSP signing and sealing as per Microsoft's NTLMv1 implementation, in the hope that knowing this will assist us in correctly implementing NTLMSSP signing for SMB packets. (Still not yet functional) This patch replaces the NTLMSSP implementation in rpc_client/cli_pipe.c with calls to libsmb/ntlmssp.c. In the process, we have gained the ability to use the more secure NT password, and the ability to sign-only, instead of having to seal the pipe connection. (Previously we were limited to sealing, and could only use the LM-password derived key). Our new client-side NTLMSSP code also needed alteration to cope with our comparatively simple server-side implementation. A future step is to replace it with calls to the same NTLMSSP library. Also included in this patch is the schannel 'sign only' patch I submitted to the team earlier. While not enabled (and not functional, at this stage) the work in this patch makes the code paths *much* easier to follow. I have also included similar hooks in rpccleint to allow the use of schannel on *any* pipe. rpcclient now defaults to not using schannel (or any other extra per-pipe authenticiation) for any connection. The 'schannel' command enables schannel for all pipes until disabled. This code is also much more secure than the previous code, as changes to our cli_pipe routines ensure that the authentication footer cannot be removed by an attacker, and more error states are correctly handled. (The same needs to be done to our server) Andrew Bartlett (This used to be commit 5472ddc9eaf4e79c5b2e1c8ee8c7f190dc285f19)
2003-07-03This patch takes the work the jerry did for beta2, and generalises it:Andrew Bartlett1-1/+1
- The 'not implmented' checks are now done by all auth modules - the ntdomain/trustdomain/winbind modules are more presise as to what domain names they can and cannot handle - The become_root() calls are now around the winbind pipe opening only, not the entire auth call - The unix username is kept seperate from the NT username, removing the need for 'clean off the domain\' in parse_net.c - All sid->uid translations are now validated with getpwuid() to put a very basic stop to logins with 'half deleted' accounts.

2003-05-12And finally IDMAP in 3_0Simo Sorce1-8/+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.

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.

2002-01-09Better explanation message for dmalloc.Martin Pool1-1/+1
Also more insertion of parenthesis to handle struct members called 'free'. You can now get useful dmalloc output, as long as it is compatible with your C library. On RH7.1 it looks like you have to rebuild dmalloc to allow free(0) by default, because something in libcrypt does that. (sigh) (This used to be commit 391cbb690196537c8b6292b42c2e27408cc7e249)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-4/+4
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)

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.

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-2/+6
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.

2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-13/+5
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 Bartlett1-29/+22
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.
