- NTLM2 fixes, don't force NTLM2 - Don't use NTLM2 for RPC, it doesn't work yet - Add comments to winbindd_pam.c - Merge 64 bit fixes and better debug messages in winbindd.c Andrew Bartlett (This used to be commit ba94e4a1ab6dc3335bbb29686ca6795d0ffad5b0)
2003-11-22(merge from 3.0)Andrew Bartlett1-245/+496
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)

2003-03-23NTLM Authentication:Andrew Bartlett1-18/+32
- 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 dcdc75ebd89f504a0f6e3a3bc5b43298858d276b)
2003-03-10Further work on NTLMSSP-based SMB signing. Current status is that I cannnotAndrew Bartlett1-12/+25
get Win2k to send a valid signiture in it's session setup reply - which it will give to win2k clients. So, I need to look at becoming 'more like MS', but for now I'll get this code into the tree. It's actually based on the TNG cli_pipe_ntlmssp.c, as it was slightly easier to understand than our own (but only the utility functions remain in any way intact...). This includes the mysical 'NTLM2' code - I have no idea if it actually works. (I couldn't get TNG to use it for its pipes either).

2003-02-15Move our NTLMSSP client code into ntlmssp.c. The intention is to provide aAndrew Bartlett1-3/+301
relitivly useful external lib from this code, and to remove the dupicate NTLMSSP code elsewhere in samba (RPC pipes, LDAP client). The code I've replaced this with in cliconnect.c is relitivly ugly, and I hope to replace it with a more general SPENGO layer at some later date.

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.

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)
2003-01-16(missed in last commit)Andrew Bartlett1-5/+8
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)
