2003-02-24Merge of server-side authentication changes to 3.0:Andrew Bartlett1-2/+2
- user_ok() and user_in_group() now take a list of groups, instead of looking for the user in the members of all groups. - The 'server_info' returned from the authentication is now kept around - in future we won't copy the sesion key, username etc, we will just referece them directly. - rhosts upgraded to use the SAM if possible, otherwise fake up based on getpwnam(). - auth_util code to deal with groups upgraded to deal with non-winbind domain members again.

This is not 100% the same as what SuSE shipped in their Samba, there is a crash bug fix, a race condition fix, and a few logic changes I'd like to discuss with Andreas. Added Andreas to (C) notices for posix_acls.c Jeremy. (This used to be commit 40eafb9dde113af9f7f1808fda22908953f7e8c3)

this means "xcopy /o" has a chance of working with ACLs that contain ACEs that use SIDs that the Samba server has no knowledge of. It's a bit hackish, Tim, can you look at my uid.c changes? (This used to be commit fe2db3148587937aa7b674c1c99036d42a3776b3)

2002-01-26 - Provide sid->name lookup support for non-unix accounts.Andrew Bartlett1-36/+33
- Rework the name -> sid lookup function to always try local lookup first (for local domain names) before trying winbind. This seems to eliminate my winbind feedback loop problems. (I don't use winbind for nsswitch, where there are almost certainly further issues). Andrew Bartlett (This used to be commit 25cadce67bc8effd4248ab993ae78e1d8511d994)
2002-01-26Rework lookup_name() to take seperate username/domain args, and to removeAndrew Bartlett1-31/+24
varioius crazy 'if winbind didn't find it' cases. This makes winbind default domain support easier to intergrate with smbd. (This used to be commit 3e71521957d579f00249679de837490aca5ba92f)
2002-01-20This patch makes the 'winbind use default domain' code interact better withAndrew Bartlett1-1/+1
smbd, and also makes it much cleaner inside winbindd. It is mostly my code, with a few changes and testing performed by Alexander Bokovoy <a.bokovoy@sam-solutions.net>. ab has tested it in security=domain and security=ads, but more testing is always appricatiated. The idea is that we no longer cart around a 'domain\user' string, we keep them seperate until the last moment - when we push that string into a pwent on onto the socket. This removes the need to be constantly parsing that string - the domain prefix is almost always already provided, (only a couple of functions actually changed arguments in all this). Some consequential changes to the RPC client code, to stop it concatonating the two strings (it now passes them both back as params). I havn't changed the cache code, however the usernames will no longer have a double domain prefix in the key string. The actual structures are unchanged - but the meaning of 'username' in the 'rid' will have changed. (The cache is invalidated at startup, so on-disk formats are not an issue here). Andrew Bartlett (This used to be commit e870f0e727952aeb8599cf93ad2650ae56eca033)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-9/+4
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)
2001-12-04added a boolean to the group mapping functions to specify if we need orJean-François Micouleau1-1/+1
not the privileges. Usually we don't need them, so the memory is free early. lib/util_sid.c: added some helper functions to check an SID. passdb/passdb.c: renamed local_lookup_rid() to local_lookup_sid() and pass an RID all the way. If the group doesn't exist on the domain SID, don't return a faked one as it can collide with a builtin one. Some rpc structures have been badly designed, they return only rids and force the client to do subsequent lsa_lookup_sid() on the domain sid and the builtin sid ! rpc_server/srv_util.c: wrote a new version of get_domain_user_groups(). Only the samr code uses it atm. It uses the group mapping code instead of a bloody hard coded crap. The netlogon code will use it too, but I have to do some test first. J.F.

2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-1/+1
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)

2001-10-29This commit is number 3 of 4.Andrew Bartlett1-1/+1
In particular this commit focuses on: Changing the Get_Pwnam code so that it can work in a const-enforced environment. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes allow for 'const' in 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 used to be commit e7634f81c5116ff4addfb7e495f54b6bb78e8f77)

2000-11-13Large commit which restructures the local password storage API.Gerald Carter1-1/+1
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)

2000-10-13Fix to allow smbd to call winbindd if it is running for all group enumeration,Jeremy Allison1-0/+226
falling back to the UNIX calls on error. This should fix all problems with smbd enumerating all users in all groups in all trusted domains via winbindd. Also changed GETDC to query 1C name rather than 1b name as only the PDC registers 1b. Jeremy. (This used to be commit 5b0038a2afd8abbd6fd4a58f5477a40d1926d498)
2000-08-09Fixed memory leak with NT tokens.Jeremy Allison1-2/+20
Added debug messages to se_access_check(). Added FULL_ACCESS acl to default acl on printers. Jeremy. (This used to be commit 7507f6f408cf8b0f8d7e2b3da54ce5fb5ef5343b)
2000-08-04Fixed up the user/group contexts when using authenticated pipes.Jeremy Allison1-2/+1
Added a become_root()/unbecome_root() (push/pop security context) around the initgroups() call to ensure it would succeed. Hmmm - I wonder if this call being done as non-root might explain any "group access" bugs we've had in the past.... Jeremy. (This used to be commit 06a65972e872f37d88b84f22ea714feebd38f6c0)
2000-08-03Added an NT_USER_TOKEN structure that is copied/passed around associatedJeremy Allison1-3/+5
with the current user. This will allow se_access_check() to quickly do a SD check without having to translate uid/gid's to SIDs. Still needs work on pipe calls. Jeremy. (This used to be commit e28d01b744b3dbd33e0e54af4e7f426fa8c082b8)
2000-08-02Started to canonicalize our handling of uid -> sid code in order toJeremy Allison1-10/+13
get ready and fix se_access_check(). Added cannonical lookup_name(), lookup_sid(), uid_to_sid(), gid_to_sid() functions that look via winbind first the fall back on local lookup. All Samba should use these rather than trying to call winbindd code directly. Added NT_USER_TOKEN struct in user_struct, contains list of NT sids associated with this user. se_access_check() should use this (cached) value rather than attempting to do the same thing itself when given a uid/gid pair. More work needs to be done to preserve these things accross security context changes (especially with the tricky pipe problem) but I'm beginning to see how this will be done..... probably by registering a new vuid for an authenticated RPC pipe and not treating the pipe calls specially. More thoughts needed - but we're almost there... Jeremy. (This used to be commit 5e5cc6efe2e4687be59085f562caea1e2e05d0a8)
