2002-03-01SECURITY FIXES:Andrew Bartlett1-6/+4
Remove a stray 'unbecome_root()' in the ntdomain an auth failure case. Only allow trust accounts to request a challange in srv_netlogon_nt.c. Currently any user can be the 'machine' for the domain logon. MERGE for 2.2. Andrew Bartlett (This used to be commit 0242d0e17827b05d8cd270f675d2595fa67fd5b9)

2002-02-18serialise all domain auth requestsAndrew Tridgell1-1/+10
this is needed because W2K will send a TCP reset to any open connections that have not done a negprot when a second connection is made. This meant that under heavy netlogon load a Samba domain member would fail authentications. Jeremy, you may wish to port this to 2.2.x (This used to be commit eb196070e62b45b113e5712f27198c50c5c95657)

2002-02-05Drastic impromvents to pam_winbind.Andrew Bartlett1-21/+2
This adds code to do generic PAM -> NTSTATUS and NTSTATUS -> PAM error conversions, and uses them to make the error handling in pam_winbind sane. In particular, pam_winbind now uses PAM error codes, not silly '-1, -2 ...' stuff, and logs the NTSTATUS error that winbind now sends over the pipe. Added code to wbinfo to display these - makes a big difference in debugging winbindd. The main change here is the code to allow pam_winbind password changing to correctly stack - This code ripped from pam_unix, and the copyright attached. (Same as for all pam modules, including pam_winbind) Andrew Bartlett (This used to be commit dc1a72f896b83bc1ad3c7bf6c12c36ace3967280)

2002-01-26Fix up a security issue with the way we handle domain groups retuned on theAndrew Bartlett1-16/+2
info3. These are RIDs, and it only makes sense to combine them with the domain SID returned with them. This is important for trusted domains, where that sid might be other than the one we currently reterive from the secrets.tdb. Also remove the become_root()/unbecome_root() wrapper from around both remaining TDB users: Both are now initialised at smbd startup.

2002-01-20This is another *BIG* change...Andrew Bartlett1-3/+1
Samba now features a pluggable passdb interface, along the same lines as the one in use in the auth subsystem. In this case, only one backend may be active at a time by the 'normal' interface, and only one backend per passdb_context is permitted outside that. This pluggable interface is designed to allow any number of passdb backends to be compiled in, with the selection at runtime. The 'passdb backend' paramater has been created (and documented!) to support this. As such, configure has been modfied to allow (for example) --with-ldap and the old smbpasswd to be selected at the same time. This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua. These two backends accept 'non unix accounts', where the user does *not* exist in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to avoid conflicts in the algroitmic mapping of RIDs, they use the values specified in the 'non unix account range' paramter - in the same way as the winbind ranges are specifed. While I was at it, I cleaned up some of the code in pdb_tdb (code copied directly from smbpasswd and not really considered properly). Most of this was to do with % macro expansion on stored data. It isn't easy to get the macros into the tdb, and the first password change will 'expand' them. tdbsam needs to use a similar system to pdb_ldap in this regard. This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I don't have the test facilities for these. I plan to incoroprate at least pdb_ldap into this scheme after consultation with Jerry. Each (converted) passdb module now no longer has any 'static' variables, and only exports 1 init function outside its .c file. The non-unix-account support in this patch has been proven! It is now possible to join a win2k machine to a Samba PDC without an account in /etc/passwd! Other changes: Minor interface adjustments: pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*. pdb_update_sam_account() no longer takes the 'override' argument that was being ignored so often (every other passdb backend). Extra checks have been added in some places. Minor code changes: smbpasswd no longer attempts to initialise the passdb at startup, this is now done on first use. pdbedit has lost some of its 'machine account' logic, as this behaviour is now controlled by the passdb subsystem directly. The samr subsystem no longer calls 'local password change', but does the pdb interactions directly. This allow the ACB_ flags specifed to be transferred direct to the backend, without interference. Doco: I've updated the doco to reflect some of the changes, and removed some paramters no longer applicable to HEAD. (This used to be commit ff354c99c585068af6dc1ff35a1f109a806b326b)

2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett3-6/+26
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)
2002-01-15Commit the auth associated changes I missed from the last commit.Andrew Bartlett2-3/+5
Also set the default value of all the allocated strings to "" to avoid changing the interface (becouse pdb_get...() would point to a null string, rather than a null pointer and parts of samba rely on that). Andrew Bartlett (This used to be commit 5b4079f748e25f21162e21b439063249baf8dca6)
2002-01-14Fix a segfault in auth/auth_domain.c error cases.Andrew Bartlett1-2/+1
This occured when the attempt to contact the PDC failed. The connection code has already shut down the connection, and 'free'ed the cli or has never initialised it in the first place. Andrew Bartlett (This used to be commit 37ce7630434c1afae5164c64438f428dd8e1b731)
2002-01-12Many thanks to Alexander Bokovoy <a.bokovoy@sam-solutions.net>.Andrew Bartlett1-0/+4
This work was sponsored by Optifacio Software Services, Inc. Andrew Bartlett (various e-mails announcements merged into some form of commit message below:) This patch which adds basics of universal groups support into Samba 3. Currently, only Winbind with RPC calls supports this, ADS support requires additional (possibly huge) work on KRB5 PAC. However, basic infrastructure is here. This patch adds: 1. Storing of universal groups for particular user logged into Samba software (smbd/ two winbind-pam methods) into netlogon_unigrp.tdb as array of uint32 supplemental group rids keyed as DOMAIN_SID/USER_RID in tdb. 2. Fetching of unversal groups for given user rid and domain sid from netlogon_unigrp.tdb. Since this is used in both smbd and winbindd, main code is in source/lib/netlogon_uingrp.c. Dependencies are added to AUTH_OBJ as UNIGRP_OBJ and WINBINDD_OBJ as UNIGRP_OBJ. This patch has had a few versions, the final version in particular: Many thanks to Andrew Bartlett for critics and comments, and partly rewritten code. New: - updated fetching code to changed byte order macros - moved functions to proper namespace - optimized memory usage by reusing caller's memory context - enhanced code to more follow Samba coding rules Todo: - proper universal group expiration after timeout (This used to be commit 80c2aefbe7c1aa363dd286a47d50c5d8b4595f43)

2002-01-09Better explanation message for dmalloc.Martin Pool1-1/+1
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)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett11-532/+535
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.

2002-01-01A farily large commit:Andrew Bartlett9-184/+158
- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c - It hasn't been used by anything else since smbpasswd lost its -j - Add a TALLOC_CTX to the auth subsytem. These are only valid for the length of the calls to the individual modules, if you want a longer context hide it in your private data. Similarly, all returns (like the server_info) should still be malloced. - Move the 'ntdomain' module (security=domain in oldspeak) over to use the new libsmb domain logon code. Also rework much of the code to use some better helper functions for the connection - getting us much better error returns (the new code is NTSTATUS). The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for the LUID feilds is sufficient, or if we should do random LUIDs as per the old code. Similarly, I'll move winbind over to this when I get a chance. This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in rpc_client, at least as far as smbd is concerned. While I've given this a basic rundown, any testing is as always appriciated. Andrew Bartlett (This used to be commit d870edce76ecca259230fbdbdacd0c86793b4837)

2001-11-26A number of things to clean up the auth subsytem a bit...Andrew Bartlett6-52/+83
We now default encrypt passwords = yes We now check plaintext passwords (however aquired) with the 'sam' backend rather than unix, if encrypt passwords = yes. (this kills off the 'local' backed. The sam backend may be renamed in its place) The new 'samstrict' wrapper backend checks that the user's domain is one of our netbios aliases - this ensures that we don't get fallback crazies with security = domain. Similarly, the code in the 'ntdomain' and 'smbserver' backends now checks that the user was not local before contacting the DC. The default ordering has changed, we now check the local stuff first - but becouse of the changes above, we will really only ever contact one auth source.
