2003-12-24(merge from 3.0)Andrew Bartlett1-4/+9
Thanks to Serassio Guido for noticing issues in our Squid NTLMSSP implementation. We were not resetting the NTLMSSP state for new negotiate packets. Andrew Bartlett (This used to be commit ada064af72e120aacd733245292e988dd696d059)
2003-11-22(merge from 3.0)Andrew Bartlett1-72/+112
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 Bartlett1-82/+82
- 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)

2003-01-16Updates 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).

encode the username, so don't decode it (users could play HTTP escaping games on usernames). Andrew Bartlett (This used to be commit 71e24d0200e71ffcf52eaa77edc89175f31a45cd)
2002-11-24Add ntlm_auth, a new program to provide a stable interface to winbind'sAndrew Bartlett1-0/+416
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)
