2002-09-06This is the 'easy' parts of the trusted domains patch n+3 patch fromAndrew Bartlett1-13/+11
Rafal Szczesniak <mimir@diament.ists.pwr.wroc.pl> It includes a conversion of make_user_info*() to NTSTATUS and some minor changes to other files. It also picks up on a nasty segfault that can occour in some security=domain cases. Andrew Bartlett (This used to be commit d1e1fc3e4bf72717b3593685f0ea5750d676952a)
2002-09-06Revert accidental commit - I'll need to do a fair bit more testing before IAndrew Bartlett1-3/+0
commit changes to NTLMSSP flags. (This used to be commit d200770796d871b3994a06fab45624068fdc5682)
2002-09-06Patch from "Stefan (metze) Metzmacher" <metze@metzemix.de>Andrew Bartlett1-0/+3
to extend the ADS_STATUS system to include NTSTATUS, and to provide a better general infrustructure for his sam_ads work. I've also added some extra failure mode DEBUG()s to parts of the code. NOTE: The ADS_ERR_OK() macro is rather sensitive to braketing issues - without the final set of brakets, the test is essentially inverted - causing some intersting 'error = success' messages... Andrew Bartlett (This used to be commit 5b9a7ab901bc311f3ad08462a8a68d133c34a8b4)
2002-08-31Add a bit of 'const' and move a lot of our 'repeditive' DEBUG() statements toAndrew Bartlett1-2/+0
'DEBUGADD', so we don't repeat headers. (Makes them much easier to read). (Based on patch by kai) Andrew Bartlett (This used to be commit 9deada345c5f89f338530c4de62835cc1eeb3d0e)
2002-08-20Based orginally by work by Kai, this patch moves our NT_TOKEN generation intoAndrew Bartlett1-2/+2
our authenticaion code - removing some of the duplication from the current code. This also gets us *much* closer to supporting a real SAM backend, becouse the SAM can give us the right info then. This also changes our service.c code, so that we do a VUID (rather than uid) cache on the connection struct, and do full NT ACL/NT_TOKEN checks (or cached equivilant) on every packet, for the same r or rw mode the whole share was open for. Andrew Bartlett (This used to be commit d8122cee059fc7098bfa7e42e638a9958b3ac902)
2002-08-17Change which session key we negotiate. This uses the NT-based session key thatAndrew Bartlett1-1/+1
we previously expected, rather than the LM based key. A Win2k SPNEGO enabled join goes a *lot* further with this option on. Andrew Bartlett (This used to be commit b224938e4e843288630cdc7c3c3931b241bd0e1a)
2002-08-16Re-add the last empty item to the NTLMSSP info list, but this time do itJim McDonough1-3/+4
with an empty string, not a NULL pointer... Also, check for security=ads before giving a kerberos spnego response. (This used to be commit 6eca417d1c29c7c18455f8290cad86fb1444e615)

exactly were you trying to do here? Andrew Bartlett (This used to be commit 81b675b54d86d196fb2035dc5d22781160518beb)
2002-08-15Fix NTLMSSP challenge command and auth response. We can now service joinsJim McDonough1-31/+37
from win2k AND still use SPNEGO (provided you don't build with kerberos...I still have to fix that, as we are not properly falling back). (This used to be commit 1f9b3d46c7c99e84b2983220f79613b7420c5ced)

2002-08-10Fix the %m security bug again - and try to make it harder to reintroduce inAndrew Bartlett1-2/+3
future. This moves us from fstrcpy() and global variables to 'get' and 'set' functions. In particular, the 'set' function sainity-checks the input, in the same way as we always have. Andrew Bartlett (This used to be commit e57a896f06b16fe7e336e1ae63a0c9e4cc75fd36)
2002-08-05This fixes a number of ADS problems, particularly with netbioslessAndrew Tridgell1-1/+13
setups. - split up the ads structure into logical pieces. This makes it much easier to keep things like the authentication realm and the server realm separate (they can be different). - allow ads callers to specify that no sasl bind should be performed (used by "net ads info" for example) - fix an error with handing ADS_ERROR_SYSTEM() when errno is 0 - completely rewrote the code for finding the LDAP server. Now try DNS methods first, and try all DNS servers returned from the SRV DNS query, sorted by closeness to our interfaces (using the same sort code as we use in replies from WINS servers). This allows us to cope with ADS DCs that are down, and ensures we don't pick one that is on the other side of the country unless absolutely necessary. - recognise dnsRecords as binary when displaying them - cope with the realm not being configured in smb.conf (work it out from the LDAP server) - look at the trustDirection when looking up trusted domains and don't include trusts that trust our domains but we don't trust theirs. - use LDAP to query the alternate (netbios) name for a realm, and make sure that both and long and short forms of the name are accepted by winbindd. Use the short form by default for listing users/groups. - rescan the list of trusted domains every 5 minutes in case new trust relationships are added while winbindd is running - include transient trust relationships (ie. C trusts B, B trusts A, so C trusts A) in winbindd. - don't do a gratuituous node status lookup when finding an ADS DC (we don't need it and it could fail) - remove unused sid_to_distinguished_name function - make sure we find the allternate name of our primary domain when operating with a netbiosless ADS DC (using LDAP to do the lookup) - fixed the rpc trusted domain enumeration to support up to approx 2000 trusted domains (the old limit was 3) - use the IP for the remote_machine (%m) macro when the client doesn't supply us with a name via a netbios session request (eg. port 445) - if the client uses SPNEGO then use the machine name from the SPNEGO auth packet for remote_machine (%m) macro - add new 'net ads workgroup' command to find the netbios workgroup name for a realm (This used to be commit e358d7b24c86a46d8c361b9e32a25d4f71a6dc00)

there were 2 bugs: 1) we were sending a null challenge when we should have sent an empty challenge 2) the password can be in unicode if unicode is negotiated. This means our client code was wrong too :( (This used to be commit 1a6dfddf6788b30fc81794b1bfe749693183b2c1)

2002-05-26Add support for NTLMv2 (tested!) with NTLMSSP.Andrew Bartlett1-17/+49
The problem was the NTLMv2 uses extra data in order to make reply/lookup more difficult. That extra data includes the hostname, and the domain. This matches Win2k (sort of) by sending this information. Win2k connects with LMCompatibilityLevel=5 without a problem. We can change the negotiation bits if we want, this should allow us to make NTLMv2 the default for other clients as well. Some of the extra #defines were found in the squid source.

2002-01-30Removed version number from file header.Tim Potter1-2/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-7/+0
Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps them around for a long time - often past the next call... This adds a getpwnam_alloc and a getpwuid_alloc to the collection. These function as expected, returning a malloced structure that can be free()ed with passwd_free(&passwd). This patch also cuts down on the number of calls to getpwnam - mostly by taking advantage of the fact that the passdb interface is already case-insensiteve. With this patch most of the recursive cases have been removed (that I know of) and the problems are reduced further by not using the sys_ interface in the new code. This means that pointers to the cache won't be affected. (This is a tempoary HACK, I intend to kill the password cache entirly). The only change I'm a little worried about is the change to rpc_server/srv_samr_nt.c for private groups. In this case we are getting groups from the new group mapping DB. Do we still need to check for private groups? I've toned down the check to a case sensitve match with the new code, but we might be able to kill it entirly. I've also added a make_modifyable_passwd() function, that copies a passwd struct into the form that the old sys_getpw* code provided. As far as I can tell this is only actually used in the pass_check.c crazies, where I moved the final 'special case' for shadow passwords (out of _Get_Pwnam()). The matching case for getpwent() is dealt with already, in lib/util_getent.c Also included in here is a small change to register the [homes] share at vuid creation rather than just in one varient of the session setup. (This picks up the SPNEGO cases). The home directory is now stored on the vuid, and I am hoping this might provide a saner way to do %H substitions. TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change the remaining sys_getpwnam() callers to use getpwnam_alloc() and move Get_Pwnam to return an allocated struct. Andrew Bartlett (This used to be commit 1d86c7f94230bc53daebd4d2cd829da6292e05da)
2002-01-11Back out the crazy notion that the NTLMSSP flags actually mean anything...Andrew Bartlett1-1/+12
Replace this with some flags that *we* define. We can do a mapping later if we actually get some more reliable info about what passwords are actually valid. Andrew Bartlett (This used to be commit 7f7a42c3e4d5798ac87ea16a42e4976c3778a76b)
2002-01-09Better explanation message for dmalloc.Martin Pool1-5/+5
Also more insertion of parenthesis to handle struct members called 'free'. You can now get useful dmalloc output, as long as it is compatible with your C library. On RH7.1 it looks like you have to rebuild dmalloc to allow free(0) by default, because something in libcrypt does that. (sigh) (This used to be commit 391cbb690196537c8b6292b42c2e27408cc7e249)
2002-01-06Get this code back to where it belongs...Andrew Bartlett1-7/+7
Apparently (and I will doublecheck) its legal to do an annoymous session setup when we negoitiated SPNEGO, but we can't do an authenticated one becouse we didn't give a challange. Andrew Bartlett (This used to be commit 08a5c5bf940fac7a779be01db01ae7d97df80f79)

(This used to be commit 17b1c83dd02035048bd38b305460c96c6c09343a)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-45/+56
The auth_authsupplied_info typedef is now just a plain struct - auth_context, but it has been modified to contain the function pointers to the rest of the auth subsystem's components. (Who needs non-static functions anyway?) In working all this mess out, I fixed a number of memory leaks and moved the entire auth subsystem over to talloc(). Note that the TALLOC_CTX attached to the auth_context can be rather long-lived, it is provided for things that are intended to live as long. (The global_negprot_auth_context lasts the whole life of the smbd). I've also adjusted a few things in auth_domain.c, mainly passing the domain as a paramater to a few functions instead of looking up lp_workgroup(). I'm hopign to make this entire thing a bit more trusted domains (as PDC) freindly in the near future. Other than that, I moved a bit of the code around, hence the rather messy diff.

2001-12-19added trusted realm support to ADS authenticationAndrew Tridgell1-5/+10
the method used for checking if a domain is a trusted domain is very crude, we should really call a backend fn of some sort. For now I'm using winbindd to do the dirty work. (This used to be commit adf44a9bd0d997ba4dcfadc564a29149531525af)
2001-12-08Ensure that 'use spnego' restricts, rather than just advises our clients.Andrew Bartlett1-1/+6
This means that if a hole is found in the spnego code, we can tell people to just set 'use spengo' in their config file while we sort it out. Other than that, preventing 'unusual' behaviour is always a good thing. Andrew Bartlett (This used to be commit a8a53c08f7d607268a3959486a850a2df50ca7a2)

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-38/+85
subystem. The particular aim is to modularized the interface - so that we can have arbitrary password back-ends. This code adds one such back-end, a 'winbind' module to authenticate against the winbind_auth_crap functionality. While fully-functional this code is mainly useful as a demonstration, because we don't get back the info3 as we would for direct ntdomain authentication. This commit introduced the new 'auth methods' parameter, in the spirit of the 'auth order' discussed on the lists. It is renamed because not all the methods may be consulted, even if previous methods fail - they may not have a suitable challenge for example. Also, we have a 'local' authentication method, for old-style 'unix if plaintext, sam if encrypted' authentication and a 'guest' module to handle guest logins in a single place. While this current design is not ideal, I feel that it does provide a better infrastructure than the current design, and can be built upon. The following parameters have changed: - use rhosts = This has been replaced by the 'rhosts' authentication method, and can be specified like 'auth methods = guest rhosts' - hosts equiv = This needs both this parameter and an 'auth methods' entry to be effective. (auth methods = guest hostsequiv ....) - plaintext to smbpasswd = This is replaced by specifying 'sam' rather than 'local' in the auth methods. The security = parameter is unchanged, and now provides defaults for the 'auth methods' parameter. The available auth methods are: guest rhosts hostsequiv sam (passdb direct hash access) unix (PAM, crypt() etc) local (the combination of the above, based on encryption) smbserver (old security=server) ntdomain (old security=domain) winbind (use winbind to cache DC connections) Assistance in testing, or the production of new and interesting authentication modules is always appreciated.
