2003-02-17This patch fixes one of my longest-standing pet hates with Samba :-).Andrew Bartlett1-15/+42
When we look see if a user is in a list, and we try to 'expand' an @group, we should lookup the user's own list of groups, rather than looking for all the members of a group. I'm sure this will fix some nasty performance issues, particularly on large domains etc. In particular, this avoids contacting winbind at all, if the group is not a winbind group. (This caused a deadlock on my winbind-on-PDC setup). The groups list always includes the user's primary group, as per the getgrouplist manpage, and my recent changes to our implementation.

2002-05-25Clean up a few unused functions, add a bit of static etc.Andrew Bartlett1-1/+1
Importantly: The removal of the silly 'delete user script' behaviour when secuity=domain. I have left the name the same - as it still does the (previously documented, but not in smb.conf(5)) sane behaviour of deleting users on request. When we decide what to do with the 'add user' functionality, we might rename it. Andrew Bartlett (This used to be commit cdcfe3671eb7570e15649b77f708e6579055e7bc)

2002-01-27Some more 'winbind default domain' support patches from Alexander BokovoyAndrew Bartlett1-0/+27
<a.bokovoy@sam-solutions.net>. This patch is designed to remove the 'special cases' required for this support. In particular this now kills off winbind_initgroups, as it appears no longer to be required. Andrew Bartlett (This used to be commit f1d8d509766e9169d39332559162cfec249bfc70)
2002-01-26Bring this code into line with new winbind_lookup_name() interface. I thinkAndrew Bartlett1-10/+23
this might need a bit more work - or at least documentation. This is certainly a worthwile little hack, as it avoids the need to invert the group database. I don't think we should allow unqualified domains here - as that allows us to distinguish between (at least some) usernames and these 'special' groups. (This used to be commit 151dd7bc6c61e19a993017e5e0b50314801e26de)
2002-01-18This is the 'winbind default domain' patch from Alexander BokovoyAndrew Bartlett1-1/+1
<a.bokovoy@sam-solutions.net>. The idea is the domain\username is rather harsh for unix systems - people don't expect to have to FTP, SSH and (in particular) e-mail with a username like that. This 'corrects' that - but is not without its own problems. As you can see from the changes to files like username.c and wb_client.c (smbd's winbind client code) a lot of assumptions are made in a lot of places about lp_winbind_seperator determining a users's status as a domain or local user. The main change I will shortly be making is to investigate and kill off winbind_initgroups() - as far as I know it was a workaround for an old bug in winbind itself (and a bug in RH 5.2) and should no longer be relevent. I am also going to move to using the 'winbind uid' and 'winbind gid' paramaters to determine a user/groups's 'local' status, rather than the presence of the seperator. As such, this functionality is recommended for servers providing unix services, but is currently less than optimal for windows clients. (TODO: remove all references to lp_winbind_seperator() and lp_winbind_use_default_domain() from smbd) Andrew Bartlett (This used to be commit 07a21fcd2311d2d9b430b99303e3532a8c1159e4)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-28/+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.

2001-12-18A fix to override the location of a user's home directory if it isTim Potter1-0/+16
specified in the [homes] section of the smb.conf file. Jeremy, can you take a look at this? This is in response to someone on the samba mailing list worrying about it. Tim. From: Phil Thompson <philnanne@mediaone.net> To: samba@lists.samba.org Subject: Different [homes] behavior in 2.2.2 X-Original-Date: Mon, 17 Dec 2001 23:09:28 -0500 Is it possible to configure samba to disregard the home directory in the passwd file when using [homes]? Even though an alternate "path" is set in [homes], the service fails since the unix home directory is invalid (nonexistent) on the server. [...] This behavior of validating the user's home dir as set in the passwd files appears to be new in 2.2.2 and the latest CVS. Anyway to work around this?

2001-10-29This commit is number 4 of 4.Andrew Bartlett1-5/+5
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)
