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)
2002-01-02Actually enforce the passdb API.Andrew Bartlett1-1/+1
Thou shalt not reference SAM_ACCOUNT members directly - always use pdb_get/pdb_set. This is achived by making the whole of SAM_ACCOUNT have a .private member, where the real members live. This caught a pile of examples, and these have beeen fixed. The pdb_get..() functions are 'const' (have been for some time) and this required a few small changes to constify other functions. I've also added some debugs to the pdb get and set, they can be removed if requested. I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb interface, but I need the flags info to do it properly. The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result. Finally, any and all testing is always appriciated - but the basics seem to work. Andrew Bartlett (This used to be commit d3dd28f6c443187b8d820d5a39c7c5b3be2fa95c)
2001-12-31ops, froget to set the values.Simo Sorce1-1/+7
jerry, can you look at theis where we use standard_sub_advanced() fns? I think this structure should be backported to 2.2 because we do not know if the SAM_ACCOUNT strings have enough space to contain the "substituted" string. (Yes, just now we know they are pstrings, but we may change them into alloced one, I'm a strong suported of alloced strings as 1024 bytes are not always enough and are often too much) (This used to be commit 29b3b5e9292805aa65e887755567abd50f74e5cb)

2001-12-06again an intrusive patch:Jean-François Micouleau1-2/+0
- removed the ugly as hell sam_logon_in_ssb variable, I changed a bit the definition of standard_sub_basic() to cope with that. - removed the smb.conf: 'domain admin group' and 'domain guest group' parameters ! We're not playing anymore with the user's group RIDs ! - in get_domain_user_groups(), if the user's gid is a group, put it first in the group RID list. I just have to write an HOWTO now ;-) J.F.

2001-11-01Various post AuthRewrite cleanups, fixups and tidyups.Andrew Bartlett1-8/+4
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.

2001-10-29This commit is number 4 of 4.Andrew Bartlett1-19/+19
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)

2001-09-29This is the passdb section of the previously mentioned commit.Andrew Bartlett1-2/+1
Of particular note is the change to pdb_free_sam() to take its sam argument by reference, allowing it to be NULLified by the SAFE_FREE() macro, and the changed to local_password_change() both to make it work and to remove the duplicate code that caused so much breakage over the last few days. - Small change in behaviour: when LOCAL_ADD_USER is set, the user doesn't actually exist locally but does exist in the passdb we don't attempt to do a GetPwnam(). (How the entry got there is another matter, and most passdbs won't allow this anyway). Andrew Bartlett (This used to be commit 6b45e342fd1ed82d7f5bd613048fe862a6a6f2a1)

2000-11-21Another large patch for the passdb rewrite.Gerald Carter1-503/+512
o added BOOL own_memory flag in SAM_ACCOUNT so we could use static memory for string pointer assignment or allocate a new string o added a reference TDB passdb backend. This is only a reference and should not be used in production because - RID's are generated using the same algorithm as with smbpasswd - a TDB can only have one key (w/o getting into problems) and we need three. Therefore the pdb_sam-getpwuid() and pdb_getsampwrid() functions are interative searches :-( we need transaction support, multiple indexes, and a nice open source DBM. The Berkeley DB (from sleepycat.com seems to fit this criteria now) o added a new parameter "private dir" as many places in the code were using lp_smb_passwd_file() and chopping off the filename part. This makes more sense to me and I will docuement it in the man pages o Ran through Insure-lite and corrected memory leaks.

2000-11-13Large commit which restructures the local password storage API.Gerald Carter1-0/+600
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)
