2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-72/+112
- 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)

2003-05-09Finally get NTLMv2 working on the client!Andrew Bartlett1-84/+29
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! Andrew Bartlett (This used to be commit 9f6a26769d345d319ec167cd0e82a45e1207ed81)
2003-05-09Added some more diagnostic tests to check out a theory that having either hashTim Potter1-12/+174
- auth with ntlmv2 and lmv2 but deliberately break the ntlmv2 hash - auth with ntlmv2 and lmv2 but deliberately break the lmv2 hash - auth with ntlm and lm but deliberately break the ntlm hash - auth with ntlm and lm but deliberately break the lm hash My theory is that the NTLM or NTLMv2 field must be correct and if it is, it doesn't matter what the value of the LM or LMv2 field is. Fixed cosmetic test name display bug. (This used to be commit 5dcde9451bd0d6a7462b77cf5ed137bfd691adaa)

Our NTLMv2 client code needs work, becouse we don't get the session key for any of the NTLMv2 stuff... Also test some of the more 'odd' auth cases - like putting the NT password into the LM feild.

2003-03-24(merge from HEAD)Andrew Bartlett1-82/+82
NTLM Authentication: - 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 ec071ca3dcbd3881dc08e6a8d7ac2ff0bcd57664)

2003-01-16Updates to the NTLMSSP code again - moving the base64 decode fuctionality outAndrew Bartlett1-29/+150
of the SWAT code, and adding a base64 encoder. The main purpose of this patch is to add NTLMSSP support to 'ntlm_auth', for use with Squid. Unfortunetly the squid side doesn't quite support what we need yet. Changes to winbind to get us the info we need, and a couple of consequential changes/cleanups in the rest of the code.

2003-01-02BIG patch...Andrew Bartlett1-1/+1
This patch makes Samba compile cleanly with -Wwrite-strings. - That is, all string literals are marked as 'const'. These strings are always read only, this just marks them as such for passing to other functions. What is most supprising is that I didn't need to change more than a few lines of code (all in 'net', which got a small cleanup of net.h and extern variables). The rest is just adding a lot of 'const'. As far as I can tell, I have not added any new warnings - apart from making all of tdbutil.c's function const (so they warn for adding that const string to struct). Andrew Bartlett (This used to be commit 92a777d0eaa4fb3a1c7835816f93c6bdd456816d)

authentication code. In particular, ntlm_auth is designed to replace the winbind authentication 'helpers' currently supplied by Squid. I have added support for the current plaintext password protocol used by Squid, and will add the real guts (NTLMSSP support) shortly. I'll merge this into 3.0 when I've got the interface more stable (error message format etc) and got the important NTLMSSP support added. Also move SWAT's URL decoding code into util_str.c, for use in both utilities. Andrew Bartlett (This used to be commit 82dbf838879e8a2d2d3f9dd5be6eda50b780b787)
