2012-04-03s3-auth: Order GENSEC mechs by priority, krb5 before NTLMSSPAndrew Bartlett1-2/+3
Otherwise, really simple clients (such as the current ntlm_auth gss-spnego client) will not select krb5. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-03-30More strlcat/strlcpy truncate checks.Jeremy Allison1-10/+45
2012-03-24lib/util: Remove obsolete sys_getpid() and sys_fork().Jelmer Vernooij1-2/+2
The performance of these is minimal (these days) and they can return invalid results when used as part of applications that do not use sys_fork(). Autobuild-User: Jelmer Vernooij <jelmer@samba.org> Autobuild-Date: Sat Mar 24 21:55:41 CET 2012 on sn-devel-104

2012-03-15s3-krb5: Remove GSS_WRAP_IOV conditionalAndrew Bartlett1-1/+1
We already confirm that we have this functionality before we set HAVE_KRB5 at configure time. Andrew Bartlett
2012-03-13s3-rpc: Decrypt with the proper session key in CreateTrustedDomainEx2.Alexander Bokovoy2-0/+29
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 Bartlett3-11/+48
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
2012-03-08s3-auth: Follow auth_ntlmssp and use auth4_context for Session SetupAndrew Bartlett1-10/+10
This patch ensures consistency in behaviour between NTLMSSP and NTLM session setup handlers. By calling the same layer that auth_ntlmssp calls, we can not only allow redirection of all authentication to the AD DC, we ensure that map to guest and username map handling is consistent, even in the file server alone. Andrew Bartlett
2012-03-04s3-auth Add make_session_info_from_pw to avoid multiple getpwnam() callsAndrew Bartlett1-12/+34
2012-03-04s3-auth: Remove security=share (depricated since 3.6).Andrew Bartlett4-193/+1
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: Provide helper routine to check password and return session_infoAndrew Bartlett2-0/+31
2012-02-24auth: Rename some elements of auth4_contextAndrew Bartlett1-3/+3
These operate on NTLM authentication, so make that clear. Andrew Bartlett
2012-02-24s3-auth: Add a way to get an auth4_context from the auth stackAndrew Bartlett4-11/+108
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
2012-02-18auth: Reorder arguments to generate_session_infoAndrew Bartlett2-4/+4

2012-02-17s3-auth: Use common gensec_ntlmsspAndrew Bartlett2-38/+3
There is no longer any samba3-specific code left here. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-02-17s3-auth: Use common gensec_ntlmssp_server_startAndrew Bartlett1-127/+1
This is now identical code, so there is no need to duplicate it. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

gensec_ntlmssp_server_start()
2012-02-17s3-auth: Only allow LM_KEY cryptography when extra options are setAndrew Bartlett1-1/+6
This crypto is incredibly poor, and can technically be enabled on an otherwise more secure connection that uses NTLM for the actual authentication leg. Therefore disable it by default. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-02-17s3-auth: Inline ntlmssp_server_start() into gensec_ntlmssp3_server_start()Andrew Bartlett1-9/+60

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>
2012-02-16Rename obscure defined constants.Christopher R. Hertel (crh)1-2/+2
Replaced the undescriptive SMB_PORT1 and SMB_PORT2 defined constants with the slightly more descriptive names NBT_SMB_PORT and TCP_SMB_PORT. Also replaced several hard-coded references to the well-known port numbers (139 and 445, respectively) as appropriate. Small changes to clarify some comments regarding the two transport types.

2012-01-30auth: Make check_password and generate_session_info hook genericAndrew Bartlett1-14/+19
gensec_ntlmssp does not need to know the internal form of the struct user_info_dc or auth_serversupplied_info. This will allow the calling logic to be put in common. Andrew Bartlett
2012-01-27s3-pdb: Break SECRETS3 dependency on PDB.Simo Sorce1-1/+1
This is causing circular depdnendcies that bring libpdb in all code and this is BAD. This change 'protects' the sid and guid of the domain by adding a special key that makes them effectively read only. Limit this temporarily to the samba 4 build, once it gets some good testing the samba4 ifdefs can be dropped. fix pdb dependencies Signed-off-by: Andreas Schneider <asn@samba.org>

This simplifies a lot of code, as we know we are always dealing with a struct gensec_security, and allows the gensec module being used to implement GSSAPI to be swapped when required for AD-server operation. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
