2009-11-14s3:is_trusted_domain: shortcut if domain name == global_sam_nameMichael Adam1-0/+4
A domain can't have a trust with itself. This saves some roundtrips to the ldap server for ldapsam. Michael

This saves some roundtrips to LDAP in an ldapsm setup. 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.

2009-05-28s3/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. Guenther (cherry picked from commit b5097d54cb74ca0ea328f9e029562f65f4a01134)
2009-04-28Fix bug #6291 - force user stop working.Jeremy Allison1-1/+37
A previous fix broke the invariant that *uid is always initialized on return from create_token_from_username(). Restore it. Jeremy.
2009-04-14Rework Samba3 to use new libcli/auth code (partial)Andrew Bartlett1-2/+3
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

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.
2009-02-21Revert "s3 auth: Add parameter that forces every user through an NSS lookup"Tim Prouty1-22/+4
After the discussion on samba-technical, it was decided that the best answer for now was to revert this change. The right way to do this is to rewrite the token api to use opaque tokens with pluggable modules. This reverts commit 8e19a288052bca5efdb0277a40c1e0fdd099cc2b.
2009-02-16s3 auth: Add parameter that forces every user through an NSS lookupZach Loafman1-4/+22
When set to yes, "force username map" forces every user, even AD users, through an NSS lookup. This allows the token to be overridden with information from NSS in certain broken environments.

2009-02-11s3: Change behavior when seeing an unknown domain.Dan Sledz1-22/+35
After a lot of testing against various Windows servers (W2K, W2K3, W2K8), within an AD domain it seems that unknown domains will only be translated to the local account domain, not the netbios name of the member server's domain. This makes samba act more like Windows.

2008-12-04Fix bug #1254 - write list not working under share-level securityJeremy Allison1-1/+1
A somewhat more elegant fix than I could use for 3.2.x or 3.0.x. Turns out the only part of check_user_ok() that needs to change for share level security is the VUID cache pieces, so I can just always use check_user_ok() for all lp_security() cases. Jeremy

2008-08-14Fix show-stopper for 3.2. Smbd depends on group SIDJeremy Allison1-0/+34
position zero being the primary group sid. Authenicating via winbindd call returned a non-sorted sid list. This fixes is for both a winbindd call and a pac list from an info3 struct.
