2007-10-10r1661: Changed the password history format so that each history entryJeremy Allison1-0/+20
consists of a 16 byte salt, followed by the 16 byte MD5 hash of the concatination of the salt plus the NThash of the historical password. Allows these to be exposed in LDAP without security issues. Jeremy. (This used to be commit 82e4036aaa2d283534a5bd8149857320fcf0d0dc)
2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-3/+3
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. This removes the 'need_reseed' parameter from generate_random_buffer(). Andrew Bartlett (This used to be commit 36741d3cf53a7bd17d361251f2bb50851cdb035f)
2007-10-10r176: Improve our fallback code for password changes - this would be betterAndrew Bartlett1-3/+9
with more correct NTLMSSP support in client and server, but it will do for now. Also implement LANMAN password only in the classical session setup code, but #ifdef'ed out. In Samba4, I'll make this run-time so we can torture it. Lanman passwords over 14 dos characters long could be considered 'invalid' (they are truncated) - so SMBencrypt now returns 'False' if it generates such a password.

another NTLMv2 combination. We should allow the NTLMv2 response to be calculated with either the domain as supplied, or the domain in UPPER case (as we always did in the past). As a client, we always UPPER case it (as per the spec), but we also make sure to UPPER case the domain, when we send it. This should give us maximum compatability.

2004-01-26This adds client-side support for the unicode/SAMR password change scheme.Andrew Bartlett1-33/+35
As well as avoiding DOS charset issues, this scheme returns useful error codes, that we can map back via the pam interface. This patch also cleans up the interfaces used for password buffers, to avoid duplication of code. Andrew Bartlett (This used to be commit 2a2b1f0c872d154fbcce71a250e23dfad085ba1e)
2003-12-17Make sure we correctly generate the lm session key.Gerald Carter1-0/+20
This fixes a problem joining a Samba domain from a vanilla win2k client that doesn't set the NTLMSSP_NEGOTIATE_NTLM2 flag. Reported on samba ml as "decode_pw: incorrect password length" when handling a samr_set_userinfo(23 or 24) RPC. (This used to be commit ef4ab8d7c497e4229d0c1deeb20d05c95bd8feb9)
2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-3/+3
- 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)

(This used to be commit 398bd14fc6e2f8ab2f34211270e179b8928a6669)
2003-08-14Change Samba to always use extended security for it's guest logins, (ie,Andrew Bartlett1-1/+1
NTLMSSP with "" username, NULL password), and add --machine-pass (-P) to all of Samba's clients. When connecting to an Active Directory DC, you must initiate the CIFS level session setup with Kerberos, not a guest login. If you don't, your machine account is demoted to NT4. Andrew Bartlett (This used to be commit 3547cb3def45a90f99f67829a533eac1ccba5e77)
2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-0/+31
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)
2003-05-09Finally get NTLMv2 working on the client!Andrew Bartlett1-28/+84
With big thanks to tpot for the ethereal disector, and for the base code behind this, we now fully support NTLMv2 as a client. In particular, we support it with direct domain logons (tested with ntlm_auth --diagnostics), with 'old style' session setups, and with NTLMSSP. In fact, for NTLMSSP we recycle one of the parts of the server's reply directly... (we might need to parse for unicode issues later). In particular, a Win2k domain controller now supplies us with a session key for this password, which means that doman joins, and non-spnego SMB signing are now supported with NTLMv2! Andrew Bartlett (This used to be commit 9f6a26769d345d319ec167cd0e82a45e1207ed81)
2003-05-05Allow the NTLMv2 functions to spit out both possible varients on the sessionAndrew Bartlett1-11/+23
key, so we can test it in ntlm_auth. I suspect the 'lm' version doesn't exist, but it's easy to change back. Andrew Bartlett (This used to be commit 5efd95622c411f123660b6613b86c7a68bba68e8)
2003-03-18Merge from HEAD:Andrew Bartlett1-99/+1
A much better SMB signing module, that allows for mulitple signing algorithms and correctly backs down from signing when the server cannot sign the reply. This also attempts to enable SMB signing on NTLMSSP connections, but I don't know what NTLMSSP flags to set yet. This would allow 'client use signing' to be set by default, for server compatability. (A seperate option value should be provided for mandetory signing, which would not back down). Andrew Bartlett (This used to be commit 1c87be7a3d127201a6ab78d22d17c971af16b86b)

2001-12-04Add 'net rpc join' to match the ADS equiv.Andrew Bartlett1-12/+5
This kills off the offending code in smbpasswd -j -Uab%c In the process we have changed from unsing compelatly random passwords to random, 15 char ascii strings. While this does produce a decrese in entropy, it is still vastly greater than we need, considering the application. In the meantime this allows us to actually *type* the machine account password duruign debugging. This code also adds a 'check' step to the join, confirming that the stored password does indeed do somthing of value :-) Andrew Bartlett (This used to be commit c0b7ee6ee547dc7ff798eaf8cb63fbe344073029)
2001-11-11Minor updates. A small dose of const.Andrew Bartlett1-1/+1
(This used to be commit 80667cb0dd1a2cdef17711c8580af9f524971cea)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-8/+8
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 4 of 4.Andrew Bartlett1-6/+6
In particular this commit focuses on: Actually adding the 'const' to the passdb interface, and the flow-on changes. Also kill off the 'disp_info' stuff, as its no longer used. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes introduces a large dose of 'const' to 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 finishes this line of commits off, your tree should now compile again :-) Andrew Bartlett (This used to be commit c95f5aeb9327347674589ae313b75bee3bf8e317)

2001-08-10A rewrite of the error handling in the libsmb client code. I've separatedTim Potter1-2/+1
out the error handling into a bunch of separate functions rather than all being handled in one big function. Fetch error codes from the last received packet: void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num); uint32 cli_nt_error(struct cli_state *); Convert errors to UNIX errno values: int cli_errno_from_dos(uint8 eclass, uint32 num); int cli_errno_from_nt(uint32 status); int cli_errno(struct cli_state *cli); Detect different kinds of errors: BOOL cli_is_dos_error(struct cli_state *cli); BOOL cli_is_nt_error(struct cli_state *cli); BOOL cli_is_error(struct cli_state *cli); This also means we now support CAP_STATUS32 as we can decode and understand NT errors instead of just DOS errors. Yay! Ported a whole bunch of files in libsmb to use this new API instead of the just the DOS error. (This used to be commit 6dbdb0d813f3c7ab20b38baa1223b0b479aadec9)
