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)
2002-01-06Some more SPNEGO fixes.Andrew Bartlett1-1/+1

2002-01-05Fix up the SPNEGO segfault.Andrew Bartlett1-2/+2
(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. Andrew Bartlett (This used to be commit 12f5515f556cf39fea98134fe3e2ac4540501048)

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)

winbindd can do a kinit this will be removed once we have code that gets a tgt and puts it in a place where cyrus-sasl can see it (This used to be commit 7d94f1b7365215a020d3678d03d820a7d086174f)
2001-11-29Make better use of the ads_init() function to get the kerberos relam etc.Andrew Bartlett1-7/+12
This allows us to use automagically obtained values in future, and the value from krb5.conf now. Also fix mem leaks etc. Andrew Bartlett (This used to be commit 8f9ce717819235d98a1463f20ac659cb4b4ebbd2)

2001-11-24added "net join" commandAndrew Tridgell1-38/+5
this completes the first stage of the smbd ADS support (This used to be commit 058a5aee901e6609969ef7e1d482a720a84a4a12)
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.

2001-11-11Kill off 'restrict anonymous' becouse it is useless in its current form.Andrew Bartlett1-47/+0
To be replaced with a real restriction in consultation with jra. (Hence why I've not touched loadparm.c). Andrew Bartlett (This used to be commit 95901449158a4ef7f95f75b22f63f6f8d43a01fe)
2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-2/+2
per-share. I beleive that almost all the things that this could have done on a per-share basis can be done with other tools, like 'force user'. Almost all the user's of this paramater used it as a global anyway... While this is one step at a time, I hope it will allow me to considerably simplfy the make_connection() code, particularly for the user-level security case. This already removes an absolute truckload of extra attempted password lookups on the guest account. Andrew Bartlett (This used to be commit 8e708332eded210c1d1fe0cebca3c9c19f054b71)
2001-11-09fix the tree so it compiles againAndrew Tridgell1-1/+1

2001-11-08Change to guest logon code.Andrew Bartlett1-58/+62
This changes the way we process guest logons - we now treat them as normal logons, but set the 'guest' flag. In particular this is needed becouse Win2k will do an NTLMSSP login with username "", therefore missing our previous guest connection code - this is getting a pain to do as a special case all over the shop. Tridge: We don't seem to be setting a guest bit for NTLMSSP, in either the anonymous or authenticated case, can you take a look at this? Also some cleanups in the check_password() code that should make some of the debugs clearer. Various other minor cleanups: - change the session code to just take a vuser, rather than having to do a vuid lookup on vuser.vuid - Change some of the global_client_caps linking - Better debug in authorise_login(): show the vuid. Andrew Bartlett (This used to be commit 62f4e4bd0aef9ade653b3f8d575d2864c166ab4d)

2001-11-01Various post AuthRewrite cleanups, fixups and tidyups.Andrew Bartlett1-3/+3
Zero out some of the plaintext passwords for paranoia Fix up some of the other passdb backends with the change to *uid_t rather than uid_t. Make some of the code in srv_netlog_nt.c clearer, is passing an array around, so pass its lenght in is definition, not as a seperate paramater. Use sizeof() rather than magic numbers, it makes things easier to read. Cope with a PAM authenticated user who is not in /etc/passwd - currently by saying NO_SUCH_USER, but this can change in future. Andrew Bartlett (This used to be commit 514c91b16baca639bb04638042bf9894d881172a)
2001-10-31This should fix up the compile with krb5.Andrew Bartlett1-7/+9
This needs to use the auth interface at some stage, but for now this will do. (This used to be commit 8dc4f2e44b150cdcdecd2f6028bf06907ff90cad)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-197/+159
code. In particular this assists tpot in some of his work, becouse it provides the connection between the authenticaion and the vuid generation. Major Changes: - Fully malloc'ed structures. - Massive rework of the code so that all structures are made and destroyed using malloc and free, rather than hanging around on the stack. - SAM_ACCOUNT unix uids and gids are now pointers to the same, to allow them to be declared 'invalid' without the chance that people might get ROOT by default. - kill off some of the "DOMAIN\user" lookups. These can be readded at a more appropriate place (probably domain_client_validate.c) in the future. They don't belong in session setups. - Massive introduction of DATA_BLOB structures, particularly for passwords. - Use NTLMSSP flags to tell the backend what its getting, rather than magic lenghths. - Fix winbind back up again, but tpot is redoing this soon anyway. - Abstract much of the work in srv_netlog_nt back into auth helper functions. This is a LARGE change, and any assistance is testing it is appriciated. Domain logons are still broken (as far as I can tell) but other functionality seems intact. Needs testing with a wide variety of MS clients. Andrew Bartlett (This used to be commit f70fb819b2f57bd57232b51808345e2319d52f6c)
