1. Fix a crash bug which should have reared its ugly head ages ago, but for some reason, remained dormant until recently. The bug pertained to libsmbclient doing a structure assignment of a cli after having opened a pipe. The pipe open code makes a copy of the cli pointer that was passed to it. If the cli is later copied (and that cli pointer that was saved is no longer valid), the pipe code will cause a crash during shutdown or when the copied cli is closed. 2. The 'type' field in enumerated shares was not being set correctly with the new RPC-based mechanism for enumerating shares. (This used to be commit 62a02b8f2a1fcb66881a9c9636e0b27e3049c5a1)

supported pipe. Netlogon is still special, as we open that twice, one to do the auth2, the other one with schannel. The client interface is completely unchanged for those who only use a single pie. cli->pipe_idx is used as the index for everything except the "real" client rpc calls, which have been explicitly converted in my last commit. Next step is to get winbind to just use a single smb connection for multiple pipes. Volker (This used to be commit dc294c52e0216424236057ca6cd35e1ebf51d0da)

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-14/+17
- 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)

2003-08-19- Fix the kerberos downgrade problem:Andrew Bartlett1-1/+5
- When connecting to the NETOGON pipe, we make a call to auth2, in order to verify our identity. This call was being made with negotiation flags of 0x1ff. This caused our account to be downgraded. If we instead make the call with flags > 1ff (such as 0x701ff), then this does not occour. - This is *not* related to the use of kerberos for the CIFS-level connection My theory is that Win2k has a test to see if we are sending *exactly* what NT4 sent - setting any other flags seems to cause us to remain intact. Also ensure that we only have 'setup schannel' code in a few places, not scattered around cmd_netlogon too. Andrew Bartlett (This used to be commit e10f0529fe9d8d245b3cd001cce6a9a86896679c)

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.

2003-07-14Jeremy requested that I get my NTLMSSP patch into CVS. He didn't requestAndrew Bartlett1-564/+493
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)

channel: - If the domain name passed to create_rpc_bind_req() is empty, use lp_workgroup() - Correctly set the auth_padding field when the send_size is a multiple of 8 bytes I've tested with nt4sp6 and win2ksp0 and it seems to work, although there are no password hashes transferred from win2k. The empty passwords are being protected by the secure channel encryption though. (This used to be commit a8c11e855611c91e94787387c62ac629232cacfa)
2003-05-11Ok, this is a hack. On a netsec bind reply I did not see anythingVolker Lendecke1-0/+20
useful in the auth verifier yet. So this patch ignores it. Really checking this would be a lot more intrusive: in rpc_api_pipe we would have to distinguish between binds and normal requests, or have more state in the netsec info of cli_state, which is also somewhat hackish.
