2003-02-22Remove 'unixsam' from the default passdb backends.Andrew Bartlett1-59/+0
The intention is to remove the muliple passdb backends, but we need the 'guest' account to always be there. If the admin adds the guest account to (say) LDAP, there will only be one backend required for operation. This helps remove some nasty behaviours with adding accounts to the system for both the RPC 'create user' and the SAMSYNC code. Users 'added' with an 'add user/machine' script won't magicly appear, and machine accounts 'pre-added' to unix, but not the smbpasswd file will not cause mayhem. This commit also implements somthing tridge discussed with me, the concept of 'default' passdb operation pointers - so that each backend does not need it's own stub funcitons wrapping the default tdb privilages/group mapping code. This also removes an implicit 'sid->name' and 'name->sid' mapping from our own local SID space, to winbind usernames. When adding mapping for NIS/LDAP non-sam users in future, we need to be careful.

2003-01-02BIG patch...Andrew Bartlett1-1/+1
This patch makes Samba compile cleanly with -Wwrite-strings. - That is, all string literals are marked as 'const'. These strings are always read only, this just marks them as such for passing to other functions. What is most supprising is that I didn't need to change more than a few lines of code (all in 'net', which got a small cleanup of net.h and extern variables). The rest is just adding a lot of 'const'. As far as I can tell, I have not added any new warnings - apart from making all of tdbutil.c's function const (so they warn for adding that const string to struct).

2002-10-21This moves the group mapping API into the passdb backend.Volker Lendecke1-0/+59
Currently this calls back to mapping.c, but we have the framework to get the information into LDAP and the passdb.tdb (should we? I think so..). This has received moderate testing with net rpc vampire and usrmgr. I found the add_groupmem segfault in add_aliasmem as well, but that will be another checkin.

2002-10-12Nice *big* patch from metze.Andrew Bartlett1-48/+48
The actual design change is relitivly small however: It all goes back to jerry's 'BOOL store', added to many of the elements in a SAM_ACCOUNT. This ensured that smb.conf defaults did not get 'fixed' into ldap. This was a great win for admins, and this patch follows in the same way. This patch extends the concept - we don't store values back into LDAP unless they have been changed. So if we read a value, but don't update it, or we read a value, find it's not there and use a default, we will not update ldap with that value. This reduced clutter in our LDAP DB, and makes it easier to change defaults later on. Metze's particular problem was that when we 'write back' an unchanged value, we would clear any muliple values in that feild. Now he can still have his mulitivalued 'uid' feild, without Samba changing it for *every* other operation. This also applies to many other attributes, and helps to eliminate a nasty race condition. (Time between get and set) This patch is big, and needs more testing, but metze has tested usrmgr, and I've fixed some pdbedit bugs, and tested domain joins, so it isn't compleatly flawed ;-). The same system will be introduced into the SAM code shortly, but this fixes bugs that people were coming across in production uses of Samba 3.0/HEAD, hence it's inclusion here.

2002-07-26Mimir has been busy with patches again, and sent in the followingAndrew Bartlett1-1/+1
patches: Andrew Bartlett From his e-mail: Below I attach the following patches as a result of my work on trusted domains support: 1) srv_samr_nt.c.diff This fixes a bug which caused to return null string as the first entry of enumerated accounts list (no matter what entry, it was always null string and rid) and possibly spoiled further names, depeding on their length. I found that while testing my 'net rpc trustdom list' against nt servers and samba server. 2) libsmb.diff Now, fallback to anonymous connection works correctly. 3) smbpasswd.c.diff Just a little fix which actually allows one to create a trusting domain account using smbpasswd 4) typos.diff As the name suggests, it's just a few typos fix :) (This used to be commit 888d595fab4f6b28318b743f47378cb7ca35d479)

to using SIDs instead of RIDs. The new funciton sid_peek_check_rid() takes an 'expected domain sid' argument. The idea here is to prevent mistakes where the SID is implict, but isn't the same one that we have in the struct. Andrew Bartlett (This used to be commit 04f9a8ff4c7982f6597c0f6748f85d66d4784901)

2002-05-18so here it is the code to introduce seriously debugggging classes.Simo Sorce1-2/+23
this is a first step only passdb stuff has beein "classized". - so what can you do? set debug level to: 1 poasdb:10 that will make all the code run at debug level 1 except the code in passdb/* files that will run at level 10 TODO: fix the man page - also smbcontrol has this nice feature so smbcontrol smbd debug 3 passdb:5 will set every smbd to have a default log level of 3 while passdb stuff will be at level 5 and so no.. minor cosmetic fix to pdbedit is there too (This used to be commit be5c3b3f5781ddc002ffcc98df04ab024dcef4ca)
2002-05-18A few things in this commit:Andrew Bartlett1-46/+53
cleanup some of the code in net_rpc_join re const warnings and fstrings. Passdb: Make the %u and %U substituions in passdb work. This is done by declaring these paramters to be 'const' and doing the substitution manually. I'm told this is us going full circle, but I can't really see a better way. Finally these things actually seem to work properly... Make the lanman code use the pdb's recorded values for homedir etc rather than the values from lp_*() Add code to set the plaintext password in the passdb, where it can decide how to store/set it. For use with a future 'ldap password change' option, or somthing like that... Add pdb_unix, so as to remove the 'not in passdb' special cases from the local_lookup_*() code. Quite small, as it uses the new 'struct passwd -> SAM_ACCOUNT' code that is now in just one place. (also used by pdb_smbpasswd) Other: Fix up the adding of [homes] at session setup time to actually pass the right string, that is the unix homedir, not the UNC path. Fix up [homes] so that for winbind users is picks the correct name. (bad interactions with the default domain code previously) Change the rpc_server/srv_lsa_nt.c code to match NT when for the SATUS_NONE_MAPPED reply: This was only being triggered on no queries, now it is on the 'no mappings' (ie all mappings failed). Checked against Win2k. Policy Question: Should SID -> unix_user.234/unix_group.364 be considered a mapping or not? Currently it isn't.

2002-04-13Better handling of uid/gid -> RID and RID -> uid/gid code.Andrew Bartlett1-11/+34
All uids and gids must create valid RIDs, becouse other code expects this, and can't handle the failure case. (ACL code in particular) Allow admins to adjust the base of the RID algorithm, so avoid clashes with users brought in from NT (for example). Put all the algorithm code back in one place, so that this change is global. Better coping with NULL sid pointers - but it still breaks a lot of stuff. BONUS: manpage entry for new paramater :-) counter based rids for normal users in tdbsam is disabled for the timebeing, idra and I will work out some things here soon I hope.

2002-04-13This is the 'multiple pdb backends' patch from ctrlsoft, aka Jelmer VernooijAndrew Bartlett1-19/+19
<jelmer@nl.linux.org>. This patch also includes major rework of pdbedit to use popt, and the addition of -i paramter (allowing the user to specify which PDBs is being operated on) and -e to export a pdb - useful for backup and testing etc. Use of -i and -e gets us pdb2pdb functionality for transition between backends, much like the sam2sam in TNG.

2002-03-02This patch merges my private LDAP tree into HEAD.Andrew Bartlett1-5/+5
The main change here is to move ldap into the new pluggable passdb subsystem and to take the LDAP location as a 'location' paramter on the 'passdb backend' line in the smb.conf. This is an LDAP URL, parsed by OpenLDAP where supported, and by hand where it isn't. It also adds the ldap user suffix and ldap machine suffix smb.conf options, so that machines added to the LDAP dir don't get mixed in with people. Non-unix account support is also added. This means that machines don't need to be in /etc/passwd or in nss_ldap's scope. This code has stood up well under my production environment, so it relitivly well tested. I'm commiting this now becouse others have shown interest in using it, and there is no point 'hording' the code :-). Andrew Bartlett (This used to be commit cd5234d7dd7309d88944b83d807c1f1c2ca0460a)

2002-01-20This is another *BIG* change...Andrew Bartlett1-189/+232
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 Bartlett1-2/+6
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.

2002-01-15Change the passdb interface to use allocated strings.Andrew Bartlett1-1/+1
These strings are allocated using talloc(), either using its own memory context stored on the SAM_ACCOUNT or one supplied by the caller. The pdb_init_sam() and pdb_free_sam() function have been modifed so that a call to pdb_free_sam() will either clean up (remove hashes from memory) and destroy the TALLOC_CTX or just clean up depending on who supplied it. The pdb_init_sam and pdb_free_sam functions now also return an NTSTATUS, and I have modified the 3 places that actually checked these returns. The only nasty thing about this patch is the small measure needed to maintin interface compatability - strings set to NULL are actually set to "". This is becouse there are too many places in Samba that do strlen() on these strings without checking if they are NULL pointers. A supp patch will follow to set all strings to "" in pdb_default_sam(). Andrew Bartlett (This used to be commit 144345b41d39a6f68d01f62b7aee64ca0d328085)
