2012-02-24s3-ntlm_auth: Convert ntlm_auth to use gensec_ntlmssp server-sideAndrew Bartlett2-0/+13
This uses the common gensec_ntlmssp server code for ntlm_auth, removing the last non-gensec use of the NTLMSSP server. Andrew Bartlett
2012-02-24auth: Rename some elements of auth4_contextAndrew Bartlett2-17/+17
These operate on NTLM authentication, so make that clear. Andrew Bartlett
2012-02-18auth: Reorder arguments to generate_session_infoAndrew Bartlett2-3/+3
This matches check_ntlm_password() and generate_session_info_pac() Andrew Bartlett Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Sat Feb 18 02:19:35 CET 2012 on sn-devel-104

2012-02-17auth: Make more of the ntlmssp code private or staticAndrew Bartlett3-96/+64
Now that there is only one gensec_ntlmssp server, some of these functions can be static For the rest, put the implemtnation of the gensec_ntlmssp code into ntlmssp_private.h Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-02-17auth: Provide a way to specify the NTLMSSP server name to GENSECAndrew Bartlett2-17/+40
This avoids us needing to assume lp_netbios_name().lp_dnsdomain() if the caller knows better. This will allow preservation of current s3 behaviour. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-02-17auth: Rearrange ntlmssp code for clarityAndrew Bartlett1-9/+8

2012-02-17auth: Set NTLMSSP_NEGOTIATE_SIGN when session key support is requiredAndrew Bartlett1-0/+3
This matches the s3 NTLMSSP server. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

gensec_ntlmssp3_server This is possible because we now supply the auth4_context abstraction that this code is looking for. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

2012-02-17auth: Move the rest of the source4 gensec_ntlmssp code to the top levelAndrew Bartlett6-2/+1099
The ntlmssp_server code will be in common shortly, and aside from a symbol name or two, moving the client code causes no harm and makes less mess. We will also get the client code in common very soon. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
2012-02-17s3-auth Hook checking passwords and generating session_info via the ↵Andrew Bartlett1-3/+0
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>
2012-02-17auth/kerberos: Move gse_get_session_key() to common code and use in ↵Andrew Bartlett1-0/+113
gensec_gssapi Thie ensures that both code bases use the same logic to determine the use of NEW_SPNEGO. Andrew Bartlett
2012-02-13auth: Pass in the SMB username (for %U) into generate_session_infoAndrew Bartlett1-0/+1

2012-02-10gensec: set flag to continue in outer for loop in gensec_use_kerberos_mechsAndrew Bartlett1-1/+5
This should be the correct fix for the valgrind erorr Volker found in 744ed53a62037a659133ccd4de2065491208ae7d. This fix avoids putting SPNEGO into the list twice when we are in the CRED_DONT_USE_KERBEROS case. Andrew Bartlett
2012-02-10Revert "gensec: Fix a memory corruption in gensec_use_kerberos_mechs"Andrew Bartlett1-2/+1
This reverts commit 744ed53a62037a659133ccd4de2065491208ae7d. The real bug here is that the second half of the outer loop should not have been run once we found spnego. Andrew Bartlett

2012-01-30gensec: inline gensec_generate_session_info() into only callerAndrew Bartlett2-34/+0
This avoids casting to and from the struct auth_user_info_dc *user_info_dc to to this, the if (user_info_dc->info->authenticated) is moved into auth_generate_session_info_wrapper(), which is the function that gensec_security->auth_context->generate_session_info points to. Andrew Bartlett
2012-01-30auth: Make check_password and generate_session_info hook genericAndrew Bartlett2-6/+4
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
2012-01-29auth: provide private pointer and do not return original PAC signaturesAndrew Bartlett1-0/+3
There is no need to return the PAC signatures via the special-purpose torture element. Instead, use a private pointer on the auth_context in conjunction with the private PAC processing method.

2012-01-11gensec: Make sure to check the optional auth_context hooks before using themAndrew Bartlett1-1/+1
These are optional to supply - some callers only provide an auth_context for the other plugin functions, and so we need to deal with this cleanly. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

2012-01-11auth: make auth4_context common to provide access to generate_session_info_pac()Andrew Bartlett1-0/+59
By providing this context, a function pointer for generate_session_info_pac() can be inserted into gensec, allowing the s3 PAC processing in an otherwise more generic gensec module. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>

The fact that this function is unimplemented is unimportant to the callers as credential caches are not handled via the auth/credentials code in s3. Andrew Bartlett Autobuild-User: Andrew Bartlett <abartlet@samba.org> Autobuild-Date: Mon Jan 9 03:24:36 CET 2012 on sn-devel-104
2011-12-29auth/kerberos: Rename memory contexts for greater clarityAndrew Bartlett1-34/+34
This should better follow the mem_ctx/tmp_ctx pattern used elsewhere in Samba. Thankyou Simo for the suggestion. Andrew Bartlett
2011-12-29s4-gensec: Move parsing of the PAC blob and creating the session_info into authAndrew Bartlett1-0/+1
This uses a single callback to handle the PAC from the DATA_BLOB format until it becomes a struct auth_session_info. This allows a seperation between the GSS acceptor code and the PAC interpretation code based on the supplied auth context.

2011-12-28credentials: Always honour the return value of E_deshash()Andrew Bartlett1-4/+2
When this returns false, the hash value is not correct as the password could not be converted into an uppercase, 14 char or less ASCII string. Andrew Bartlett
2011-12-28gensec: Allow an alternate set of modules to be specifiedAndrew Bartlett2-1/+11
This will allow s3 to specify modules to use as a list, rather than needing to start the individual module with gensec_start_mech_by_ops() Andrew Bartlett

2011-12-03Revert making public of the samba-module library.Jelmer Vernooij2-8/+8
This library was tiny - containing just two public functions than were themselves trivial. The amount of overhead this causes isn't really worth the benefits of sharing the code with other projects like OpenChange. In addition, this code isn't really generically useful anyway, as it can only load from the module path set for Samba at configure time. Adding a new library was breaking the API/ABI anyway, so OpenChange had to be updated to cope with the new situation one way or another. I've added a simpler (compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.
