posix_acls When a user owns a file, but does not have specific permissions on that file, we need to make up the user permissions. This change ensures that the first thing that we do is to look up the SID, and confirm it is a user. Then, we avoid the getpwnam() and directly create the token via the SID.

2012-06-16s3-auth: Remove auth_netlogondAndrew Bartlett1-2/+0
auth_netlogond was an important module in the development of the combined Samba 4.0, and was the first module to link smbd with the AD authentication store, showing that it was possible for NTLM authentication to be offloaded to the AD server components. We now have auth_samba4, which provides the full GENSEC stack to smbd, which also matches exactly the group membership and privileges assignment and which is supported and tested as part of the official Samba 4.0 release configuration.

2012-03-13s3-rpc: Decrypt with the proper session key in CreateTrustedDomainEx2.Alexander Bokovoy1-0/+1
On LSA and SAMR pipes session_key is truncated to 16 byte when doing encryption/decryption. However, this was not done for trusted domain-related modifying operations. As result, Samba 4 client libraries do not work against Samba 3 while working against Windows 2008 r2. Solved this by introducing "session_extract_session_key()" function that allows to specify intent of use of the key.

2012-03-08s3-auth: Remove single-implementation plugin layerAndrew Bartlett1-0/+40
The ->get_ntlm_challenge and ->check_ntlm_password elements of struct auth_context were only ever initialised to a single value. Make it easier to follow by just calling the function directly. Andrew Bartlett
2012-03-04s3-auth: Remove security=share (depricated since 3.6).Andrew Bartlett1-12/+0
This patch removes security=share, which Samba implemented by matching the per-share password provided by the client in the Tree Connect with a selection of usernames supplied by the client, the smb.conf or guessed from the environment. The rationale for the removal is that for the bulk of security=share users, we just we need a very simple way to run a 'trust the network' Samba server, where users mark shares as guest ok. This is still supported, and the smb.conf options are documented at https://wiki.samba.org/index.php/Public_Samba_Server At the same time, this closes the door on one of the most arcane areas of Samba authentication. Naturally, full user-name/password authentication remain available in security=user and above. This includes documentation updates for username and only user, which now only do a small amount of what they used to do.

2012-02-24s3-auth: Add a way to get an auth4_context from the auth stackAndrew Bartlett1-0/+1
This will allow us to use the same layer that auth_ntlmssp does in the non-SPNEGO session setup, which will in turn make the authentication code more consistent in the AD server case. Andrew Bartlett

auth4_context This avoids creating a second auth_context, as it is a private pointer in the auth4_context that has already been passed in, and makes the gensec_ntlmssp code agnostic to the type of authentication backend behind it. This will in turn allow the ntlmssp server code to be further merged. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

2012-01-05s3-auth use gensec directly rather than via auth_generic_stateAndrew Bartlett1-5/+1
This is possible because the s3 gensec modules are started as normal gensec modules, so we do not need a wrapper any more. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

2011-08-03s3-auth rename auth_ntlmssp_steal_session_info()Andrew Bartlett1-3/+3
There is no longer any theft of memory as the underlying routines now produce a new auth_session_info for this caller, allocating it on the supplied memory context. Andrew Bartlett

2011-08-03s3-auth set session_info->sanitized_username in create_local_token()Andrew Bartlett1-0/+1
Rather than passing this value around the callers, and eventually setting it in register_existing_vuid(), we simply pass it to create_local_token(). This also removes the need for auth_ntlmssp_get_username(). Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>

2011-07-20s3-auth Use struct auth3_session_info outside the auth subsystemAndrew Bartlett1-7/+9
This seperation between the structure used inside the auth modules and in the wider codebase allows for a gradual migration from struct auth_serversupplied_info -> struct auth_session_info (from auth.idl) The idea here is that we keep a clear seperation between the structure before and after the local groups, local user lookup and the session key modifications have been processed, as the lack of this seperation has caused issues in the past. Andrew Bartlett Signed-off-by: Andrew Tridgell <tridge@samba.org>
2011-07-20s3-auth Add struct auth3_session_info to aid transition to auth_session infoAndrew Bartlett1-0/+3
This will allow a gradual conversion of the required elements from the current struct auth_serversupplied_info. This commit adds the structure definition and some helper functions to copy between the two structures. At this stage these structures and functions are IDENTICAL to the existing code, and so show the past history of that code. The plan is to slowly modify them over the course of the patch series, so that the changes being made a clear. By using a seperate structure to auth_serversupplied_info we can remove elements that are not needed after the authentication, and we can choose a layout that best reflects the needs of runtime users, rather than the internals of the authentication subsystem. By eventually using the auth_session_info from auth.idl, we will gain a single session authorization structure across the whole codebase, allowing more code to be shared, and a much more transparent process for forwarding authorization credentials over the named pipe proxy.

2011-04-05s3-auth use create_local_token() to transform server_info -> session_infoAndrew Bartlett1-8/+12
Before a auth_serversupplied_info struct can be used for authorization, the local groups and privileges must be calculated. create_local_token() now copies the server_info, and then sets the calulated token and unix groups. Soon, it will also transform the result into an expanded struct auth_session_info. Until then, the variable name (server_info vs session_info provides a clue to the developer about what information has been entered in the structure). By moving the calls to create_local_token within the codebase, we remove duplication, and ensure that the session key (where modified) is consistently copied into the new structure. Andrew Bartlett
2011-04-04s3-auth consolidate create_local_token() into make_server_info_krb5()Andrew Bartlett1-2/+2
