2012-07-17s4-auth: Make sure we use the correct credential state.Andreas Schneider1-1/+6
If we create a copy of the credential state we miss updates to the credentials. To establish a netlogon schannel connection we create client credentials and authenticate with them using dcerpc_netr_ServerAuthenticate2() For this we call netlogon_creds_client_authenticator() which increases the sequence number and steps the credentials. Lets assume the sequence number is 1002. After a successful authentication we get the server credentials and we send bind a auth request with the received creds. This sets up gensec and the gensec schannel module created a copy of the client creds and stores it in the schannel auth state. So the creds stored in gensec have the sequence number 1002. After that we continue and need the client credentials to call dcerpc_netr_LogonGetCapabilities() to verify the connection. So we need to increase the sequence number of the credentials to 1004 and step the credentials to the next state. The server always does the same and everything is just fine here. The connection is established and we want to do another netlogon call. So we get the creds from gensec and want to do a netlogon call e.g. dcerpc_netr_SamLogonWithFlags. We get the needed creds from gensec. The sequence number is 1002 and we talk to the server. The server is already ahead cause we are already at sequence number 1004 and the server expects it to be 1006. So the server gives us ACCESS_DENIED cause we use a copy in gensec.

2012-05-23Introduce system MIT krb5 build with --with-system-mitkrb5 option.Alexander Bokovoy1-0/+1
System MIT krb5 build also enabled by specifying --without-ad-dc When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level configure in WAF build we are trying to detect and use system-wide MIT krb5 libraries. As result, Samba 4 DC functionality will be disabled due to the fact that it is currently impossible to implement embedded KDC server with MIT krb5. Thus, --with-system-mitkrb5/--without-ad-dc build will only produce * Samba 4 client libraries and their Python bindings * Samba 3 server (smbd, nmbd, winbindd from source3/) * Samba 3 client libraries In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture. This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
2012-05-23gensec_gssapi: Make it possible to build with MIT krb5Simo Sorce1-10/+20
We need to ifdef out some minor things here because there is no available API to set these options in MIT. The realm and canonicalize options should be not interesting in the client case. Same for the send_to_kdc hacks. Also the OLD DES3 enctype is not at all interesting. I am not aware that Windows will ever use DES3 and no modern implementation relies on that enctype anymore as it has been fully deprecated long ago, so we can simply ignore it.

2012-05-04s4-auth-krb: smb_rd_req_return_stuff is used only in gensec_krb5Simo Sorce4-1/+114
Make it clearly a gensec_krb5 accessory file. This function should never be used anywhere else. This function was copied out from the Heimdal tree and is kept in a separate file for clarity and to keep the original license boilerplate.
2012-04-25lib/replace: split out GSSAPI from lib/replace/system/kerberos.h into ↵Alexander Bokovoy1-3/+1
lib/replace/system/gssapi.h With waf build include directories are defined by dependencies specified to subsystems. Without proper dependency <gssapi/gssapi.h> cannot be found for embedded Heimdal builds when there are no system-wide gssapi/gssapi.h available. Split out GSSAPI header includes in a separate replacement header and use that explicitly where needed.

2011-12-29s4-gensec Remove fallback for simple privilegesAndrew Bartlett1-6/+2
This makes the dependencies simpler, as this code path is no longer required. (That is, it makes no sense to have an NTLM login without an auth context, and the gensec_gssapi and gensec_krb5 modules call the PAC blob function below instead). Andrew Bartlett
2011-12-29s4-torture: Demonstrate handling of the PAC in a custom auth_contextAndrew Bartlett2-59/+5
This demonstrates how a different function pointer can be supplied to handle the PAC blob, without depending on the provisioned samdb etc. Andrew Bartlett
2011-12-29s4-gensec: Move parsing of the PAC blob and creating the session_info into authAndrew Bartlett4-146/+152
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.

Windows-Members of NT4/Samba3 domains, send MechTypes: 1.3.6.1.4.1.311.2.2.10 [NTLMSSP] 1.2.840.48018.1.2.2 [krb5 broken] 1.2.840.113554.1.2.2 [krb5] MechToken for NTLMSSP. This patch makes sure we start NTLMSSP with the given MechToken, instead of trying to pass the NTLMSSP MechToken to the krb5 backend first.

2011-10-18gensec: move event context from gensec_*_init() to gensec_update()Andrew Bartlett5-41/+48
This avoids keeping the event context around on a the gensec_security context structure long term. In the Samba3 server, the event context we either supply is a NULL pointer as no server-side modules currently use the event context. Andrew Bartlett Signed-off-by: Stefan Metzmacher <metze@samba.org>
