2009-04-14Rework Samba3 to use new libcli/auth code (partial)Andrew Bartlett1-0/+1
This commit is mostly to cope with the removal of SamOemHash (replaced by arcfour_crypt()) and other collisions (such as changed function arguments compared to Samba3). We still provide creds_hash3 until Samba3 uses the credentials code in netlogon server Andrew Bartlett

2007-10-10r19058: Implement "user cannot change password", and complete "user must changeJim McDonough1-1/+1
password at next logon" code. The "password last set time" of zero now means "user must change password", because that's how windows seems to use it. The "can change" and "must change" times are now calculated based on the "last set" time and policies. We use the "can change" field now to indicate that a user cannot change a password by putting MAX_TIME_T in it (so long as "last set" time isn't zero). Based on this, we set the password-can-change bit in the faked secdesc. (This used to be commit 21abbeaee9b7f7cff1d34d048463c30cda44a2e3)

to make full use of the new talloc() interface. Discussed with Volker and Jeremy. * remove the internal mem_ctx and simply use the talloc() structure as the context. * replace the internal free_fn() with a talloc_destructor() function * remove the unnecessary private nested structure * rename SAM_ACCOUNT to 'struct samu' to indicate the current an upcoming changes. Groups will most likely be replaced with a 'struct samg' in the future. Note that there are now passbd API changes. And for the most part, the wrapper functions remain the same. While this code has been tested on tdb and ldap based Samba PDC's as well as Samba member servers, there are probably still some bugs. The code also needs more testing under valgrind to ensure it's not leaking memory. But it's a start...... (This used to be commit 19b7593972480540283c5bf02c02e5ecd8d2c3f0)

2007-10-10r11573: Adding Andrew Bartlett's patch to make machine accountJeremy Allison1-6/+9
logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes the auth module interface to 2 (from 1). The effect of this is that clients can access resources as a machine account if they set these flags. This is the same as Windows (think of a VPN where the vpn client authenticates itself to a VPN server using machine account credentials - the vpn server checks that the machine password was valid by performing a machine account check with the PDC in the same was as it would a user account check. I may add in a restriction (parameter) to allow this behaviour to be turned off (as it was previously). That may be on by default. Andrew Bartlett please review this change carefully. Jeremy.

2004-04-03Fix most of bug #169.Andrew Bartlett1-1/+2
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)
2004-02-21Add calls to password lockout functions. Should now work against tdbsam only.Jim McDonough1-0/+38

2003-12-30Move our basic password checking code from inside the authenticationAndrew Bartlett1-345/+1
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 Bartlett1-148/+219
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 Bartlett1-19/+45
- 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)
