2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-1/+1
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork(). For other systems, we now only re-seed after a fork, and on startup. No need to do it per-operation. This removes the 'need_reseed' parameter from generate_random_buffer(). Andrew Bartlett (This used to be commit 36741d3cf53a7bd17d361251f2bb50851cdb035f)

2007-10-10r516: On GNU/Linux distributions which allow to use both 2.4 and 2.6 kernelsAlexander Bokovoy1-0/+6
there is SYS_utimes syscall defined at compile time in glibc-kernheaders but it is available on 2.6 kernels only. Therefore, we can't rely on syscall at compile time but have to check that behaviour during program execution. An easy workaround is to have replacement for utimes() implemented within our wrapper and do not rely on syscall at all. Thus, if REPLACE_UTIME is defined already (by packager), skip these syscall shortcuts. (This used to be commit e278e2e6e095b1c01eab307d55edf2cde48dcba2)

server had said something (such as an error). Andrew Bartlett (This used to be commit c05016a2f750960c40387c1d6aba9f6841f66a3b)
2007-10-10r188: Add a new 'helper protocol' to ntlm_auth.Andrew Bartlett1-2/+202
This protocol looks rather like SMTP headers/LDAP: NT-Domain: TESTWG Username: abartlet ... Password: foo Challenge-response passwords are in hexideciaml, while any 'plain' string can be base64 encoded when like this: Password:: Zm9vCg== (the :: indicates it, just like LDAP - I hope) The protocol is not final, so it is #ifdef DEVELOPER for now (so nobody starts to rely on it until I'm happy), but we may as well get this into subversion. My intention is to use this to power the next version of my PPP/ntlm_auth plugin, and hopefully entice a FreeRadius plugin out of the woods. Andrew Bartlett (This used to be commit 8efdd957ba8310515242ba2979ff07130a0b1a3a)

2004-04-03Fix most of bug #169.Andrew Bartlett1-0/+1
For a (very) long time, we have had a bug in Samba were an NTLMv2-only PDC would fail, because it converted the password into NTLM format for checking. This patch performs the direct comparison required for interactive logons to function in this situation. It also removes the 'auth flags', which simply where not ever used. Natrually, this plays with the size of structures, so rebuild, rebuild rebuild... Andrew Bartlett (This used to be commit 9598593bcf2d877b1d08cd6a7323ee0bc160d4ba)
2004-03-24Fix bugzilla # 1208Jim McDonough1-1/+2
Winbind tickets expired. We now check the expiration time, and acquire new tickets. We couln't rely on renewing them, because if we didn't get a request before they expired, we wouldn't have renewed them. Also, there is a one-week limit in MS on renewal life, so new tickets would have been needed after a week anyway. Default is 10 hours, so we should only be acquiring them that often, unless the configuration on the DC is changed (and the minimum is 1 hour). (This used to be commit c2436c433afaab4006554a86307f76b6689d6929)

"allow_bad_conv" boolean parameter that allows broken iconv conversions to work. Gets rid of the nasty errno checks in mangle_hash2 and check_path_syntax and allows correct return code checking. Jeremy. (This used to be commit 7b96765c23637613f079d37566d95d5edd511f05)
2004-02-08Make this table static const.Andrew Bartlett1-1/+1
Andrew Bartlett (This used to be commit 0686bc9e076c722e33dd9b236cf7c33d448c3b34)
2004-01-08This merges in my 'always use ADS' patch. Tested on a mix of NT and ADSAndrew Bartlett1-5/+10
domains, this patch ensures that we always use the ADS backend when security=ADS, and the remote server is capable. The routines used for this behaviour have been upgraded to modern Samba codeing standards. This is a change in behaviour for mixed mode domains, and if the trusted domain cannot be reached with our current krb5.conf file, we will show that domain as disconnected. This is in line with existing behaviour for native mode domains, and for our primary domain. As a consequence of testing this patch, I found that our kerberos error handling was well below par - we would often throw away useful error values. These changes move more routines to ADS_STATUS to return kerberos errors. Also found when valgrinding the setup, fix a few memory leaks. While sniffing the resultant connections, I noticed we would query our list of trusted domains twice - so I have reworked some of the code to avoid that. Andrew Bartlett (This used to be commit 7c34de8096b86d2869e7177420fe129bd0c7541d)

Push the unix username into utf8 for it's trip across the socket. Andrew Bartlett (This used to be commit 3225f262b18bdcf326d3bfd031dac169bd9347c9)
2003-12-30Try to gain a bit more consistancy in the output of usernames from ntlm_auth:Andrew Bartlett1-11/+23
Instead of returning a name in DOMAIN\user format, we now return it in the same way that nsswtich does - following the rules of 'winbind use default domain', in the correct case and with the correct seperator. This should help sites who are using Squid or the new SASL code I'm working on, to match back to their unix usernames.

2003-12-30Move our basic password checking code from inside the authenticationAndrew Bartlett1-54/+254
subsystem into a seperate file - ntlm_check.c. This allows us to call these routines from ntlm_auth. The purpose of this exercise is to allow ntlm_auth (when operating as an NTLMSSP server) to avoid talking to winbind. This should allow for easier debugging. ntlm_auth itself has been reorgainised, so as to share more code between the SPNEGO-wrapped and 'raw' NTLMSSP modes. A new 'client' NTLMSSP mode has been added, for use with a Cyrus-SASL module I am writing (based on vl's work) Andrew Bartlett (This used to be commit 48315e8fd227978e0161be293ad4411b45e3ea5b)
2003-12-30Refactor our authentication and authentication testing code.Andrew Bartlett1-342/+181
The next move will be to remove our password checking code from the SAM authentication backend, and into a file where other parts of samba can use it. The ntlm_auth changes provide for better use of common code. Andrew Bartlett (This used to be commit 2375abfa0077a884248c84614d5109f57dfdf5b1)

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!
