2002-01-20This is another *BIG* change...Andrew Bartlett1-2/+2
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/+5
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.

In particular this commit focuses on: Actually adding the 'const' to the passdb interface, and the flow-on changes. Also kill off the 'disp_info' stuff, as its no longer used. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes introduces a large dose of 'const' to the Samba tree. There are a number of good reasons to do this: - I want to allow the SAM_ACCOUNT structure to move from wasteful pstrings and fstrings to allocated strings. We can't do that if people are modifying these outputs, as they may well make assumptions about getting pstrings and fstrings - I want --with-pam_smbpass to compile with a slightly sane volume of warnings, currently its pretty bad, even in 2.2 where is compiles at all. - Tridge assures me that he no longer opposes 'const religion' based on the ability to #define const the problem away. - Changed Get_Pwnam(x,y) into two variants (so that the const parameter can work correctly): - Get_Pwnam(const x) and Get_Pwnam_Modify(x). - Reworked smbd/chgpasswd.c to work with these mods, passing around a 'struct passwd' rather than the modified username --- This finishes this line of commits off, your tree should now compile again :-) Andrew Bartlett (This used to be commit c95f5aeb9327347674589ae313b75bee3bf8e317)

2001-10-02Fixed up the change password bug when not using PAM.Jeremy Allison1-16/+32
The problem is we were trying to use mask_match as a generic wildcard matcher for UNIX strings (like the password prompts). We can't do that - we need a unix_wild_match (re-added into lib/util.c) as the ms_fnmatch semantics for empty strings are completely wrong. This caused partial reads to be accepted as correct passwd change responses when they were not.... Also added paranioa test to stop passwd change being done as root with no %u in the passwd program string. Jeremy. (This used to be commit 9333bbeb7627c8b21a3eaeae1683c34e17d14bf0)

2001-09-29Fix up a number of intertwined issues:Andrew Bartlett1-47/+46
The big one is a global change to allow us to NULLify the free'ed pointer to a former passdb object. This was done to allow idra's SAFE_FREE() macro to do its magic, and to satisfy the input test in pdb_init_sam() for a NULL pointer to start with. This NULL pointer test was what was breaking the adding of accounts up until now, and this code has been reworked to avoid duplicating work - I hope this will avoid a similar mess-up in future. Finally, I fixed a few nasty bugs where the pdb_ fuctions's return codes were being ignored. Some of these functions malloc() and are permitted to fail. Also, this caught a nasty bug where pdb_set_lanman_password(sam, NULL) acheived precisely didilly-squat, just returning False. Now that we check the returns this bug was spotted. This could allow different LM and NT passwords. - the pdbedit code needs to start checking these too, but I havn't had a chance to fix it. I have also fixed up where some of the password changing code was using the pdb_set functions to store *internal* data. I assume this is from a previous lot of mass conversion work... Most likally (and going on past experience) I have missed somthing, probably in the LanMan password change code which I havn't yet been able to test, but this lot is in much better shape than it was before. If all this is too much to swallow (particularly for 2.2.2) then just adding a sam_pass = NULL to the particular line of passdb.c should do the trick for the ovbious bug.

the pam password change code to ensure that existing and working password chat scripts don't break with 2.2.1. PAM password changing has to be explicitly requested. Allowed wildcards in pam password change matching (matches password chat script matching). Had to add const (sorry Tim :-) to ms_fnmatch() to stop warnings. Don't worry - the const changes are isolated and don't cause any other warnings :-). Jeremy. (This used to be commit 47b4d82536c09bffe3a0d9917fa31d935f1be7d8)

2000-11-13Large commit which restructures the local password storage API.Gerald Carter1-94/+92
Currently the only backend which works is smbpasswd (tdb, LDAP, and NIS+) are broken, but they were somewhat broken before. :) The following functions implement the storage manipulation interface /*The following definitions come from passdb/pdb_smbpasswd.c */ BOOL pdb_setsampwent (BOOL update); void pdb_endsampwent (void); SAM_ACCOUNT* pdb_getsampwent (void); SAM_ACCOUNT* pdb_getsampwnam (char *username); SAM_ACCOUNT* pdb_getsampwuid (uid_t uid); SAM_ACCOUNT* pdb_getsampwrid (uint32 rid); BOOL pdb_add_sam_account (SAM_ACCOUNT *sampass); BOOL pdb_update_sam_account (SAM_ACCOUNT *sampass, BOOL override); BOOL pdb_delete_sam_account (char* username); There is also a host of pdb_set..() and pdb_get..() functions for manipulating SAM_ACCOUNT struct members. Note that the struct passdb_ops {} has gone away. Also notice that struct smb_passwd (formally in smb.h) has been moved to passdb/pdb_smbpasswd.c and is not accessed outisde of static internal functions in this file. All local password searches should make use of the the SAM_ACCOUNT struct and the previously mentioned functions. I'll write some documentation for this later. The next step is to fix the TDB passdb backend, then work on spliting the backends out into share libraries, and finally get the LDAP backend going. What works and may not: o domain logons from Win9x works o domain logons from WinNT 4 works o user and group enumeration as implemented by Tim works o file and print access works o changing password from Win9x & NT ummm...i'll fix this tonight :) If I broke anything else, just yell and I'll fix it. I think it should be fairly quite. -- jerry (This used to be commit 0b92d0838ebdbe24f34f17e313ecbf61a0301389)

1998-11-29weekend work. user / group database API.Luke Leighton1-1/+1
- split sam_passwd and smb_passwd into separate higher-order function tables - renamed struct smb_passwd's "smb_user" to "unix_user". added "nt_user" plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd password databases to fill in the blank entries that are not obtained from whatever password database API instance is being used. NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c for the only example outside of the password database APIs i could find. - added query_useraliases code to rpcclient. - dealt with some nasty interdependencies involving non-smbd programs and the password database API. this is still not satisfactorily resolved completelely, but it's the best i can do for now. - #ifdef'd out some password database options so that people don't mistakenly set them unless they recompile to _use_ those options. lots of debugging done, it's still not finished. the unix/NT uid/gid and user-rid/group-rid issues are better, but not perfect. the "BUILTIN" domain is still missing: users cannot be added to "BUILTIN" groups yet, as we only have an "alias" db API and a "group" db API but not "builtin-alias" db API...
