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)

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.

authentication. NTLM2 is a version of NTLM, that involves both a client and server challenge, and the creating of a new (presuable more secure) session key. Unfortunetly this is not quite the same as NTLMv2, and we don't know how to get the session key. I suggest looking very closely at what MSCHAPv2, and other MS auth protocols do...

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 Bartlett1-4/+6
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)

NTLM Authentication: - Add a 'privileged' mode to Winbindd. This is achieved by means of a directory under lockdir, that the admin can change the group access for. - This mode is now required to access with 'CRAP' authentication feature. - This *will* break the current SQUID helper, so I've fixed up our ntlm_auth replacement: - Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a challenge. - Use this to make our ntlm_auth utility suitable for use in current Squid 2.5 servers. - Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates are needed. - Now uses fgets(), not x_fgets() to cope with Squid environment (I think somthing to do with non-blocking stdin). - Add much more robust connection code to wb_common.c - it will not connect to a server of a different protocol version, and it will automatically try and reconnect to the 'privileged' pipe if possible. - This could help with 'privileged' idmap operations etc in future. - Add a generic HEX encode routine to util_str.c, - fix a small line of dodgy C in StrnCpy_fn() - Correctly pull our 'session key' out of the info3 from th the DC. This is used in both the auth code, and in for export over the winbind pipe to ntlm_auth. - Given the user's challenge/response and access to the privileged pipe, allow external access to the 'session key'. To be used for MSCHAPv2 integration. Andrew Bartlett (This used to be commit ec071ca3dcbd3881dc08e6a8d7ac2ff0bcd57664)

2003-01-28Factor out common code in the NTLMSSP/SPNEGO code.Andrew Bartlett1-4/+0
The idea here is to seperate, as much as possible, the SPNEGO layer from the NTLMSSP layer. This not only helps us with protocol correctness, but also should allow further mechinisms to be added with relitive ease. I indend to make the kerberos code use this shortly. I've never seen the 'zero length blob' form of the anonymous login, so I've removed that case. Andrew Bartlett (This used to be commit a8773c9f825539c5bc17e4200b16d7ebbe0b7620)

Change the 'cookie' to be the ntlmssp_context, and use the 'auth_context' on that to store the cookie. Ensures that simple callbacks can 'just work'. Also make it clear that we are doing a pull_string into a pstring, not just any sized buffer. Andrew Bartlett (This used to be commit c7793f27188e658b7fc6336aa51d367eab36fc17)
