2003-11-22(merge from 3.0)Andrew Bartlett1-11/+15
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)

2003-04-06SMB signing updates - this gets NTLMSSP signing workin to the point where IAndrew Bartlett1-8/+9
just need to get the verifiction code working - we get back a signiture from the server, and just can't verify it yet. This also brings the short-packet checks into common code, and breaks the connection if the server sends a signed reply, on an established connection, that fails the test. This breaks our read/write code at the moment, as we need to keep a list of outstanding packets. (signing is not enabled by default, unless the server demands it) Not for 3.0 till I fix the outstanding packet list. Andrew Barlett (This used to be commit 808d1fcf20153970d587cb631a08607beb09703a)

2003-03-10Further work on NTLMSSP-based SMB signing. Current status is that I cannnotAndrew Bartlett1-30/+150
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).

2003-03-09Change the way we sign SMB packets, to a function pointer interface.Andrew Bartlett1-0/+329
The intention is to allow for NTLMSSP and kerberos signing of packets, but for now it's just what I call 'simple' signing. (aka SMB signing per the SNIA spec) Andrew Bartlett (This used to be commit b9cf95c3dc04a45de71fb16e85c1bfbae50e6d8f)
