Remove unused utility function. Andrew Bartlett (This used to be commit af8248e67bb0f83124dcd250fee5d06a12fe257b)
2004-01-26(merge from 3.0)Andrew Bartlett1-33/+35
This adds client-side support for the unicode/SAMR password change scheme. 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 8063b8b6c2eb30cb116988e265fb289109d7c348)
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 14558c942beb05cd12c0e40c1bb30c3dcde8ce48)
2003-11-22(merge from 3.0)Andrew Bartlett1-3/+3
Changes all over the shop, but all towards: - 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... Andrew Bartlett (This used to be commit 57a895aaabacc0c9147344d097d333793b77c947)

2003-03-09Change the way we sign SMB packets, to a function pointer interface.Andrew Bartlett1-99/+1
The intention is to allow for NTLMSSP and kerberos signing of packets, but for now it's just what I call 'simple' signing. (aka SMB signing per the SNIA spec) Andrew Bartlett (This used to be commit b9cf95c3dc04a45de71fb16e85c1bfbae50e6d8f)

2003-02-09(only for HEAD at the moment).Andrew Bartlett1-7/+5
Add NTLMv2 support to our client, used when so configured ('client use NTLMv2 = yes') and only when 'client use spengo = no'. (A new option to allow the client and server ends to chose spnego seperatly). NTLMv2 signing doesn't yet work, and NTLMv2 is not done for NTLMSSP yet. Also some parinoia checks in our input parsing. Andrew Bartlett (This used to be commit 85e9c060eab59c7692198f14a447ad59f05af437)

2003-02-01We now have client-side SMB signing support!Andrew Bartlett1-4/+7
This checking allows us to connect to Microsoft servers the use SMB signing, within a few restrictions: - I've not get the NTLMSSP stuff going - it appears to work, but if you break the sig - say by writing a zero in it - it still passes... - We don't currently verfiy the server's reply - It works against one of my test servers, but not the other... However, it provides an excellent basis to work from. Enable it with 'client signing' in your smb.conf. Doc to come (tomorrow) and this is not for 3.0, till we get it complete. The CIFS Spec is misleading - the session key (for NTLMv1 at least) is the standard session key, ie MD4(NT#). Thanks to jra for the early work on this. Andrew Bartlett (This used to be commit 1a2738937e3d80b378bd0ed33cd8d395fba2d3c3)

2002-08-26Updates!Andrew Bartlett1-14/+46
- Don't print an uninitialised buffer in service.c - Change some charcnv.c functions to take smb_ucs2_t ** instead of void ** - Update NTLMv2 code to use dynamic buffers - Update experimental SMB signing code - still more work to do - Move sys_getgrouplist() to SAFE_FREE() and do a DEBUG() on initgroups() failure. Andrew Bartlett (This used to be commit de1964f7fa855022258a84556b266100b917444b)
2002-07-20Try to fix up warnings - particularly on the IRIX 64 bit compiler (which had aAndrew Bartlett1-2/+2
distinction between uchar and char). Lots of const etc. Andrew Bartlett (This used to be commit 8196ee908e10db2119e480fe1b0a71b31a16febc)
2002-07-20Fix up char/uchar casts etc. Fix up comments on some of the password hashAndrew Bartlett1-4/+4

2002-07-20Add support for a weird behaviour apparently used by Win9X pass-throughAndrew Bartlett1-2/+2
authentication - we can have an NT hash in the LM hash feild. (I need to double-check this fix with tpot, who discovered it). Also remove silly casts back and forth between uchar and char. Andrew Bartlett (This used to be commit 07e2b36311f91d7a20865a2ccc94716772e53fd7)
2002-06-16Two things: Check how many paramaters that the LDAP libs take for theAndrew Bartlett1-4/+6
rebind proc (some give an extra paramter to pass a void* paramater) and some small changes for the SMB signing code to reset things when the signing starts, and to 'turn off' signing if the session setup failed. Andrew Bartlett (This used to be commit a8805a34e5d96eeb5ffe15681b241d5a449a6144)
2002-06-16Fix up some of the SMB signing code:Andrew Bartlett1-0/+10
The problem was that *all* packets were being signed, even packets before signing was set up. (This broke the session request). This fixes it to be an 'opt in' measure - that is, we only attempt to sign things after we have got a valid, non-guest session setup as per the CIFS spec. I've not tested this against an MS server, becouse my VMware is down, but at least it doesn't break the build farm any more. Andrew Bartlett (This used to be commit 1dc5a8765876c1ca822e454651f8fd4a551965e9)

2002-06-07A couple of updates for the SmbEncrypt code, and some of its users.Andrew Bartlett1-1/+1
(const, takes unix string as arg) Also update cli_full_connection to take NULL pointers as 'undefined' correctly, and therefore do its own lookup etc. This what was intended, but previously you needed to supply a 0.0.0.0 IP address. Andrew Bartlett (This used to be commit 8fb1a9c6ba07dbf04a6aa1e30fa7bbd4c676ed28)
2002-05-25Update some of the LM hash code to better respect the seperation betweenAndrew Bartlett1-32/+41
unix and DOS strings. This pushes all the 'have to uppercase, must be 14 chars' stuff behind the the interface. Andrew Bartlett (This used to be commit dec650efa8ab1466114c2e6d469320a319499ea0)

2002-01-30Removed version number from file header.Tim Potter1-2/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
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)
2001-10-31More const.Andrew Bartlett1-2/+2

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)

2001-07-07Add backend encryption support for NTLMv2.Andrew Bartlett1-1/+96
The leg-work for this was done by the folks at samba-tng.org, I'm just bringing it accross to HEAD. The MD5 implementation is seperatly derived, and does not have the copyright problems that the one in TNG has. Also add const to a few places where it makes sence.
