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)
2000-11-04Fix for admin user being ignored.Jeremy Allison1-0/+1
Jeremy. (This used to be commit f0dcc39d34202ed67d778ff40166856d4c2ad87b)
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)

2000-05-02split the username in the vuser structure into a separateAndrew Tridgell1-1/+1
userdom_struct. As the name implies this also contains a domain (unused at the moment). This will be important shortly, as operation in appliance mode needs the domain to be always carried with the username. (This used to be commit ee8546342d5be90e730372b985710d764564b124)

1999-12-12delineation between smb and msrpc more marked. smbd now constructsLuke Leighton1-9/+115
pdus, and then feeds them over either a "local" function call or a "remote" function call to an msrpc service. the "remote" msrpc daemon, on the other side of a unix socket, then calls the same "local" function that smbd would, if the msrpc service were being run from inside smbd. this allows a transition from local msrpc services (inside the same smbd process) to remote (over a unix socket). removed reference to pipes_struct in msrpc services. all msrpc processing functions take rpcsrv_struct which is a structure containing state info for the msrpc functions to decode and create pdus. created become_vuser() which does everything not related to connection_struct that become_user() does. removed, as best i could, connection_struct dependencies from the nt spoolss printing code. todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific info on a per-connection basis, and if the connection dies then so does the info, and that's a fairly serious problem. had to put pretty much everything that is in user_struct into parse_creds.c to feed unix user info over to the msrpc daemons. why? because it's expensive to do unix password/group database lookups, and it's definitely expensive to do nt user profile lookups, not to mention pretty difficult and if you did either of these it would introduce a complication / unnecessary interdependency. so, send uid/gid/num_groups/gid_t* + SID+num_rids+domain_group_rids* + unix username + nt username + nt domain + user session key etc. this is the MINIMUM info identified so far that's actually implemented. missing bits include the called and calling netbios names etc. (basically, anything that can be loaded into standard_sub() and standard_sub_basic()...) (This used to be commit aa3c659a8dba0437c17c60055a6ed30fdfecdb6d)
1999-06-13Moved code that changes the pw_passwd entry (i.e shadow password andTim Potter1-1/+1
weird unixware stuff) into _Get_Pwnam() to fix a memory allocation bug. Note that the Get_Pwnam() function now returns a const struct passwd * as a hint to other developers not to change entries in the struct passwd. (This used to be commit 36d7cb4ccc42268e8e6a7b783c945d1853624958)
1999-04-01Ken McDonell from SGI was interested in adding some profilingAndrew Tridgell1-0/+4
capabilities to Samba so that Samba could talk to the SGI PCP (Performance Co-Pilot) apps. This change adds a profiling shared memory area and uses it to count two fairly trivial things, the number of uid switches and the number of SMB packets processes. To add more just edit include/profile.h and then increment it at the right place. I've also added a -P switch to smbstatus to dump the profile area. (This used to be commit ef3d61a80ad0b87c196a63ef2bd4fe8fc3863bd0)
