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.

2004-03-27Merge from HEAD the SMB signing patch that I developed a couple of weeksAndrew Bartlett1-9/+14
ago. This patch re-adds support for 'optional' SMB signing. It also ensures that we are much more careful about when we enable signing, particularly with on-the-fly smb.conf reloads. The client code will now attempt to use smb signing by default, and disable it if the server doesn't correctly support it.

2004-03-24Fix bugzilla # 1208Jim McDonough1-1/+1
Winbind tickets expired. We now check the expiration time, and acquire new tickets. We couln't rely on renewing them, because if we didn't get a request before they expired, we wouldn't have renewed them. Also, there is a one-week limit in MS on renewal life, so new tickets would have been needed after a week anyway. Default is 10 hours, so we should only be acquiring them that often, unless the configuration on the DC is changed (and the minimum is 1 hour).

2004-01-08This merges in my 'always use ADS' patch. Tested on a mix of NT and ADSAndrew Bartlett1-14/+17
domains, this patch ensures that we always use the ADS backend when security=ADS, and the remote server is capable. The routines used for this behaviour have been upgraded to modern Samba codeing standards. This is a change in behaviour for mixed mode domains, and if the trusted domain cannot be reached with our current krb5.conf file, we will show that domain as disconnected. This is in line with existing behaviour for native mode domains, and for our primary domain. As a consequence of testing this patch, I found that our kerberos error handling was well below par - we would often throw away useful error values. These changes move more routines to ADS_STATUS to return kerberos errors. Also found when valgrinding the setup, fix a few memory leaks. While sniffing the resultant connections, I noticed we would query our list of trusted domains twice - so I have reworked some of the code to avoid that.

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-35/+64
- 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)

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)

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)

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!
