2003-11-22(merge from 3.0)Andrew Bartlett1-1/+1
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)

2003-02-15Move our NTLMSSP client code into ntlmssp.c. The intention is to provide aAndrew Bartlett1-3/+53
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.

2003-02-09(only for HEAD at the moment).Andrew Bartlett1-1/+2
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 Bartlett1-49/+18
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 Bartlett1-1/+1
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)
2003-01-13Updates to our NTLMSSP code:Andrew Bartlett1-13/+48
This tries to extract our server-side code out of sessetup.c, and into a more general lib. I hope this is only a temporay resting place - I indend to refactor it again into an auth-subsystem independent lib, using callbacks. Move some of our our NTLMSSP #defines into a new file, and add two that I found in the COMsource docs - we seem to have a double-up, but I've verified from traces that the NTLMSSP_TARGET_TYPE_{DOMAIN,SERVER} is real. This code also copes with ASCII clients - not that we will ever see any here, but I hope to use this for HTTP, were we can get them. Win2k authenticates fine under forced ASCII, btw. Tested with Win2k, NTLMv2 and Samba's smbclient. Andrew Bartlett (This used to be commit b6641badcbb2fb3bfec9d00a6466318203ea33e1)

However, it does not work with Win2K over 445 with raw NTLMSSP! (This used to be commit 53e4975337be2cab3ee89f2f62e5659855365b73)

2002-08-31Add a bit of 'const' and move a lot of our 'repeditive' DEBUG() statements toAndrew Bartlett1-16/+18
'DEBUGADD', so we don't repeat headers. (Makes them much easier to read). (Based on patch by kai) Andrew Bartlett (This used to be commit 9deada345c5f89f338530c4de62835cc1eeb3d0e)
2002-08-30convert the LDAP/SASL code to use GSS-SPNEGO if possibleAndrew Tridgell1-3/+1
we now do this: - look for suported SASL mechanisms on the LDAP server - choose GSS-SPNEGO if possible - within GSS-SPNEGO choose KRB5 if we can do a kinit - otherwise use NTLMSSP This change also means that we no longer rely on having a gssapi library to do ADS. todo: - add TLS/SSL support over LDAP - change to using LDAP/SSL for password change in ADS (This used to be commit b04e91f660d3b26d23044075d4a7e707eb41462d)

from win2k AND still use SPNEGO (provided you don't build with kerberos...I still have to fix that, as we are not properly falling back). (This used to be commit 1f9b3d46c7c99e84b2983220f79613b7420c5ced)
2002-05-26Add support for NTLMv2 (tested!) with NTLMSSP.Andrew Bartlett1-1/+42
The problem was the NTLMv2 uses extra data in order to make reply/lookup more difficult. That extra data includes the hostname, and the domain. This matches Win2k (sort of) by sending this information. Win2k connects with LMCompatibilityLevel=5 without a problem. We can change the negotiation bits if we want, this should allow us to make NTLMv2 the default for other clients as well. Some of the extra #defines were found in the squid source.
