2010-01-14s3:auth: fix account unlock regression introduced with fix for bug #4347Michael Adam1-7/+5
By an oversight, the patchset for #4347 made the unlocking of a locked account after the lockout duration ineffective. Thanks to Björn for finding this! Michael
2010-01-12s3:auth: add comment to nulling out stolen sampassMichael Adam1-0/+4
Adding this comment makes me think, I could also have changed make_server_info_sam() talloc_move instead of talloc_steal, but that would have changed the signature... Well the comment is a first step. :-) Michael

2010-01-07s3:auth:check_sam_security: null out sampass after it has been stolen.Michael Adam1-0/+1
So that a later talloc_free would not harm. I could have used talloc_move instead of talloc steal in make_server_info_sam(), but this would have required a change of the signature. Michael
2010-01-07s3:auth:sam_password_ok: take username, acct_ctrl and nt/lm hashes, not sampassMichael Adam1-14/+20
This is in preparation to extending check_sam_security to also check against the password history before updating the bad password count. This way, sam_password_ok can more easily be reused for that purpose. Michael
2010-01-07s3:auth: use data_blob_null instead of data_blob(NULL, 0) in sam_password_ok()Michael Adam1-2/+2
This way it is more explicit that there is no allocated data here that may leak. Michael
2010-01-07s3:auth:sam_password_ok: fix allocation of a data blob.Michael Adam1-1/+1
data_blob(mem_ctx, 16) does not use mem_ctx as a talloc ctx but copies 16 bytes from mem_ctx into the newly allocated data blob. This can not have been intentional. A blank uint8_t array of length 16 is allocated by passing NULL instead of mem_ctx. And using data_blob_talloc(mem_ctx, NULL, 16) adds the allocated blank 16 byte array to mem_ctx - so this is what must have been intended. Michael

2009-08-21s3: fix bug #6650, authentication at member servers when winbindd is not runningMichael Adam1-1/+1
Authentication of domain users on the member server fails when winbindd is not running. This is because the is_trusted_domain() check behaves differently when winbindd is running and when it isn't: Since wb_is_trusted_domain() calls wbcDomainInfo(), and this will also give a result for our own domain, this succeeds for the member server's own domain when winbindd is running. When winbindd is not running, is_trusted_domain() checks (and possibly updates) the trustdom cache, and this does the lsa_EnumTrustDom() rpc call to the DC which does not return its own domain. In case of winbindd not running, before 3.4, the domain part was _silently_ mapped to the workgroup in auth_util.c:make_user_info_map(), which effectively did nothing in the member case. But then the parameter "map untrusted to domain" was introduced and the mapping was made to the workstation name instead of the workgroup name by default unless "map untrusted to domain = yes". (Commits d8c54fddda2dba3cbc5fc13e93431b152813892e, 5cd4b7b7c03df6e896186d985b6858a06aa40b3f, and fbca26923915a70031f561b198cfe2cc0d9c3aa6) This was ok as long as winbindd was running, but with winbindd not running, these changes actually uncovered the above logic bug in the check. So the correct check is to treat the workgroup as trusted / or known in the member case. This is most easily achieved by not comparing the domain name against get_global_sam_name() which is the host name unless for a DC but against my_sam_name() which is the workgroup for a DC and for a member, too. (These names are not very intuitive...) I admit that this is a very long commit message for a one-liner, but this has needed some tracking down, and I think the change deserves some justification.

2009-08-19Fix bug #6647 - get_root_nt_token: getpwnam("root") failed!Jeremy Allison1-2/+2
Not all systems may have a "root" user, but all must have a passwd entry for a uid of zero. Jeremy.
2009-07-28Added prefer_ipv4 bool parameter to resolve_name().Jeremy Allison1-1/+1
W2K3 DC's can have IPv6 addresses but won't serve krb5/ldap or cldap on those addresses. Make sure when we're asking for DC's we prefer IPv4. If you have an IPv6-only network this prioritizing code will be a no-op. And if you have a mixed network then you need to prioritize IPv4 due to W2K3 DC's. Jeremy.

2009-05-28s3/auth map NULL domains to our global sam nameSteven Danneman1-9/+3
This is an addendum to d8c54fdd, which made make_user_info_map() match Windows behavior by mapping untrusted domains given to smbd on the wire with the users credentials to smbd's global sam name. This fix was being circumvented in the case where the client passed a NULL domain. Vista clients do this. In that case smbd was always remapping the name to the machine workgroup. The NULL domain case should also be mapped to the global sam name. Removing the code in this patch, causes us to fall down to the logic added in d8c54fdd and properly map the domain.

2009-05-07s3-auth: use full 16byte session key in make_user_info_netlogon_interactive().Günther Deschner1-2/+1
Patch from Jeremy. With this patch, I was able to join Windows 7 RC to a Samba3 DC, and login into a Samba 3 Domain. There are still two registry settings required: HKLM\System\CCS\Services\LanmanWorkstation\Parameters DWORD DomainCompatibilityMode = 1 DWORD DNSNameResolutionRequired = 0 Do *not* modify the other netlogon registry parameters that were passed around, they weaken security.

2009-02-26s3: fix guest auth when winbindd is runningSteven Danneman1-7/+7
This fix is very subtle. If a server is configured with "security = share" and "guest ok = yes" and winbindd is running authorization will fail during tree connect. This is due to our inability to map the guest sid S-1-5-21-X-501 to a uid through sid_to_uid(). Winbindd is unaware of the hard coded mapping between this sid and whatever uid the name in lp_guestaccount() is assigned. So sid_to_uid() fails and we exit create_token_from_username() without ever calling pdb_getsampwsid() which IS aware of the hard coded mapping. This patch just reorganizes the code, moving sid_to_uid() down to the block of code in which it is needed, avoiding this early failure.
