portion of NTLMv2 key exchange. Also revert the default for 'client ntlmv2 auth' to no. This caused no ends of grief in different cases. And based on abartlet's mail.... > All I care about at this point is that we use NTLMv2 > in our client code when connecting to a server that > supports it. There is *no* way to tell this. The server can't tell us, because it doesn't know what it's DC supports. The DC can't tell us, because it doesn't know what the trusted DC supports. One DC might be Win2k, and the PDC could be an older NT4. (This used to be commit fe585d49cc3df0d71314ff43d3271d276d7d4503)

Server code *should* also work (I'll check shortly). May be the odd memory leak. Problem was we (a) weren't setting signing on in the client krb5 sessionsetup code (b) we need to ask for a subkey... (c). The client and server need to ask for local and remote subkeys respectively. Thanks to Paul Nelson @ Thursby for some sage advice on this :-). Jeremy.

2003-07-14Fix SMB signing when using NTLMSSP...Andrew Bartlett1-2/+5
It's so simple now I know how it works - and it has nothing to do with NTLMSSP (it's just a slightly different use of the old algorithm). :-). Note: This is actually less secure then the non-NTLMSSP code, as there is no per-session random data included for NTLM logins. (NTLMv2 is better, fortunetly). Andrew Bartlett (This used to be commit 95ec8317d4c6817d192bcd52eec44a22286e10ee)
2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-0/+6
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)

*) consolidates the dc location routines again (dns and netbios) get_dc_list() or get_sorted_dc_list() is the authoritative means of locating DC's again. (also inludes a flag to get_dc_list() to define if this should be a DNS only lookup or not) (however, if you set "name resolve order = hosts wins" you could still get DNS queries for domain name IFF ldap_domain2hostlist() fails. The answer? Fix your DNS setup) *) enabled DOMAIN<0x1c> lookups to be funneled through resolve_hosts resulting in a call to ldap_domain2hostlist() if lp_security() == SEC_ADS *) enables name cache for winbind ADS backend *) enable the negative connection cache for winbind ADS backend *) removes some old dead code *) consolidates some duplicate code *) moves the internal_name_resolve() to use an IP/port pair to deal with SRV RR dns replies. The namecache code also supports the IP:port syntax now as well. *) removes 'ads server' and moves the functionality back into 'password server' (which can support "hostname:port" syntax now but works fine with defaults depending on the value of lp_security()) (This used to be commit d7f7fcda425bef380441509734eca33da943c091)
2003-06-08Enforce 'client plaintext auth', 'client lanman auth' and 'client ntlmv2 auth'.Andrew Bartlett1-9/+49
(this now causes things like the LANMAN protocol and contacting servers with 'encrypt passwords = no' set to fail, if configured) 'client ntlmv2 auth' (a BOOL) forces both plaintext and lanman off, and is the most secure setting for compatible hosts. Perhaps we should change this to 'client minimum auth'? Andrew Bartlett (This used to be commit e1fb681e4c921456fde154b87687722a18ed4aac)

2003-05-09Finally get NTLMv2 working on the client!Andrew Bartlett1-3/+12
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!

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)
2003-04-23Add a check to ensure that the server returns the correct device type, notAndrew Bartlett1-3/+0
just the correct error. This should help us avoid breaking NT4 IPC$ connections, for example. This has required that we don't overwrite the device type for IPC$ in our tcon&X code, but only smbwrapper even uses it, and a server that doesn't send a correct dev type breaks other things pretty badly. In any case, I'll 'fix' smbwrapper :-). Andrew Bartlett (This used to be commit a93057efcb6e639be05b7bdcb9729ed8f39f5f62)

2003-03-18Merge from HEAD:Andrew Bartlett1-50/+44
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)

2002-07-01The 17-bit length field in the header contains the number ofChristopher R. Hertel1-1/+8
bytes which follow the header, not the full packet size. [Yes, the length field is either 17-bits, or (per the RFCs) it is a 16-bit length field preceeded by an 8-bit flags field of which only the low-order bit may be used. If that bit is set, then add 65536 to the 16-bit length field. (In other words, it's a 17-bit unsigned length field.) ...unless, of course, the transport is native TCP [port 445] in which case the length field *might* be 24-bits wide.] Anyway, the change is a very minor one. We were including the four bytes of the header in the length count and, as a result, sending four bytes of garbage at the end of the SESSION REQUEST packet. Small fix in function cli_session_request(). (This used to be commit d08471688b65371eb3de73b03a8ffaee86659ba0)
