2003-07-23convert snprintf() calls using pstrings & fstringsGerald Carter1-1/+1
to pstr_sprintf() and fstr_sprintf() to try to standardize. lots of snprintf() calls were using len-1; some were using len. At least this helps to be consistent. (This used to be commit 9f835b85dd38cbe655eb19021ff763f31886ac00)
2003-07-03This patch takes the work the jerry did for beta2, and generalises it:Andrew Bartlett1-3/+3
- The 'not implmented' checks are now done by all auth modules - the ntdomain/trustdomain/winbind modules are more presise as to what domain names they can and cannot handle - The become_root() calls are now around the winbind pipe opening only, not the entire auth call - The unix username is kept seperate from the NT username, removing the need for 'clean off the domain\' in parse_net.c - All sid->uid translations are now validated with getpwuid() to put a very basic stop to logins with 'half deleted' accounts.

2003-06-30* cleanup more DC name resolution issues in check_*domain_security()Gerald Carter1-209/+51
* is_trusted_domain() is broken without winbind. Still working on this. * get_global_sam_name() should return the workgroup name unless we are a standalone server (verified by volker) * Get_Pwnam() should always fall back to the username (minus domain name) even if it is not our workgroup so that TRUSTEDOMAIN\user can logon if 'user' exists in the local list of accounts (on domain members w/o winbind) Tested using Samba PDC with trusts (running winbindd) and a Samba 3.0 domain member not running winbindd. notes: make_user_info_map() is slightly broken now due to the fact that is_trusted_domain() only works with winbindd. disabled checks temporarily until I can sort this out. (This used to be commit e1d6094d066d4c16ab73075caba40a1ae6c56b1e)
2003-06-29Here's the code to make winbindd work on a Samba DCGerald Carter1-1/+2
to handle domain trusts. Jeremy and I talked about this and it's going in as working code. It keeps winbind clean and solves the trust problem with minimal changes. To summarize, there are 2 basic cases where the deadlock would occur. (1) lookuping up secondary groups for a user, and (2) get[gr|pw]nam() calls that fall through the NSS layer because they don't exist anywhere. o To handle case #1, we bypass winbindd in sys_getgrouplist() unless the username includes the 'winbind separator'. o Case #2 is handled by adding checks in winbindd to return failure if we are a DC and the domain matches our own. This code has been tested using basic share connections, domain logons, and with pam_winbind (both with and without 'winbind use default domain'). The 'trustdomain' auth module should work as well if an admin wants to manually create UNIX users for acounts in the trusted domains. Other misc fixes: * we need to fix check_ntlm_password() to be able to determine if an auth module is authoritative over a user (NT_STATUS_WRONG_PASSWORD, etc...). I worked around my specific situation, but this needs to be fixed. the winbindd auth module was causing delays. * fix named server mutex deadlock between trust domain auth module and winbindd looking up a uid * make sure SAM_ACCOUNT gets stored in the server_info struct for the _net_sam_logon() reply. Configuration details: The recommended method for supporting trusts is to use winbind. The gets us around some of the server mutex issues as well. * set 'files winbind' for passwd: and group: in /etc/nsswitch.conf * create domain trusts like normal * join winbind on the pdc to the Samba domain using 'net rpc join' * add normal parameters to smb.conf for winbind * set 'auth method = guest sam winbind' * start smbd, nmbd, & winbindd Problems that remain: * join a Windows 2k/XP box to a Samba domain. * create a 2-way trust between the Samba domain and an NT domain * logon to the windows client as a user from theh trusted domain * try to browse server in the trusted domain (or other workstations). an NT client seems to work ok, but 2k and XP either prompt for passwords or fail with errors. apparanently this never got tested since no one has ever been able to logon as a trusted user to a Samba domain from a Windows client. (This used to be commit f804b590f9dbf1f0147c06a0a2f12e221ae6fc3b)

map to guest = bad user works again when "trustdomain" is listed as last auth method. Also clean up some more DC location calls. (This used to be commit 77a5b1032f39b8d20925721b719fdcfff910cb06)
2003-06-25large change:Gerald Carter1-1/+1
*) consolidates the dc location routines again (dns and netbios) get_dc_list() or get_sorted_dc_list() is the authoritative means of locating DC's again. (also inludes a flag to get_dc_list() to define if this should be a DNS only lookup or not) (however, if you set "name resolve order = hosts wins" you could still get DNS queries for domain name IFF ldap_domain2hostlist() fails. The answer? Fix your DNS setup) *) enabled DOMAIN<0x1c> lookups to be funneled through resolve_hosts resulting in a call to ldap_domain2hostlist() if lp_security() == SEC_ADS *) enables name cache for winbind ADS backend *) enable the negative connection cache for winbind ADS backend *) removes some old dead code *) consolidates some duplicate code *) moves the internal_name_resolve() to use an IP/port pair to deal with SRV RR dns replies. The namecache code also supports the IP:port syntax now as well. *) removes 'ads server' and moves the functionality back into 'password server' (which can support "hostname:port" syntax now but works fine with defaults depending on the value of lp_security()) (This used to be commit d7f7fcda425bef380441509734eca33da943c091)
2003-06-23* s/get_dc_name/rpc_dc_name/g (revert a previous change)Gerald Carter1-1/+1
* move back to qsort() for sorting IP address in get_dc_list() * remove dc_name_cache in cm_get_dc_name() since it slowed things down more than it helped. I've made a note of where to add in the negative connection cache in the ads code. Will come back to that. * fix rpcclient to use PRINTER_ALL_ACCESS for set printer (instead of MAX_ALLOWED) * only enumerate domain local groups in our domain * simplify ldap search for seqnum in winbindd's rpc backend (This used to be commit f8cab8635b02b205b4031279cedd804c1fb22c5b)
2003-06-21merge of the netsamlogon caching code from APPLIANCE_HEADGerald Carter1-1/+1
This replaces the universal group caching code (was originally based on that code). Only applies to the the RPC code. One comment: domain local groups don't show up in 'getent group' that's easy to fix. Code has been tested against 2k domain but doesn't change anything with respect to NT4 domains. netsamlogon caching works pretty much like the universal group caching code did but has had much more testing and puts winbind mostly back in sync between branches.

- better error codes than NT_STATUS_UNSUCCESSFUL for domain logon errors - make auth_winbind load the ntdomain module if winbind isn't there. - use new trusted domains cache to determine if the domain is valid. Andrew Bartlett (This used to be commit ec8d6524c6b0c70927a2b57aab71d9e3a7f8a150)
2003-04-21Merge from HEAD - save the type of channel used to contact the DC.Andrew Bartlett1-2/+8
This allows us to join as a BDC, without appearing on the network as one until we have the database replicated, and the admin changes the configuration. This also change the SID retreval order from secrets.tdb, so we no longer require a 'net rpc getsid' - the sid fetch during the domain join is sufficient. Also minor fixes to 'net'.

2003-03-24(merge from HEAD)Andrew Bartlett1-7/+0
NTLM Authentication: - Add a 'privileged' mode to Winbindd. This is achieved by means of a directory under lockdir, that the admin can change the group access for. - This mode is now required to access with 'CRAP' authentication feature. - This *will* break the current SQUID helper, so I've fixed up our ntlm_auth replacement: - Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a challenge. - Use this to make our ntlm_auth utility suitable for use in current Squid 2.5 servers. - Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates are needed. - Now uses fgets(), not x_fgets() to cope with Squid environment (I think somthing to do with non-blocking stdin). - Add much more robust connection code to wb_common.c - it will not connect to a server of a different protocol version, and it will automatically try and reconnect to the 'privileged' pipe if possible. - This could help with 'privileged' idmap operations etc in future. - Add a generic HEX encode routine to util_str.c, - fix a small line of dodgy C in StrnCpy_fn() - Correctly pull our 'session key' out of the info3 from th the DC. This is used in both the auth code, and in for export over the winbind pipe to ntlm_auth. - Given the user's challenge/response and access to the privileged pipe, allow external access to the 'session key'. To be used for MSCHAPv2 integration. Andrew Bartlett (This used to be commit ec071ca3dcbd3881dc08e6a8d7ac2ff0bcd57664)

2002-03-02Allow Samba to trust NT4 Domains.Andrew Bartlett1-16/+121
This commit builds on the auth subsystem to give Samba support for trusting NT4 domains. It is off by default, but is enabled by adding 'trustdomain' to the 'auth methods' smb.conf paramater. Tested against NT4 only - there are still some issues with the join code for Win2k servers (spnego stuff). The main work TODO involves enumerating the trusted domains (including the RPC calls to match), and getting winbind to run on the PDC correctly. Similarly, work remains on getting NT4 to trust Samba domains. Andrew Bartlett (This used to be commit ac8c24a9a888a3f916e8b40238b936e6ad743ef7)
2002-03-01SECURITY FIXES:Andrew Bartlett1-6/+4
Remove a stray 'unbecome_root()' in the ntdomain an auth failure case. Only allow trust accounts to request a challange in srv_netlogon_nt.c. Currently any user can be the 'machine' for the domain logon. MERGE for 2.2. Andrew Bartlett (This used to be commit 0242d0e17827b05d8cd270f675d2595fa67fd5b9)

this is needed because W2K will send a TCP reset to any open connections that have not done a negprot when a second connection is made.

info3. These are RIDs, and it only makes sense to combine them with the domain SID returned with them.

This work was sponsored by Optifacio Software Services, Inc. Andrew Bartlett (various e-mails announcements merged into some form of commit message below:) This patch which adds basics of universal groups support into Samba 3. Currently, only Winbind with RPC calls supports this, ADS support requires additional (possibly huge) work on KRB5 PAC. However, basic infrastructure is here. This patch adds: 1. Storing of universal groups for particular user logged into Samba software (smbd/ two winbind-pam methods) into netlogon_unigrp.tdb as array of uint32 supplemental group rids keyed as DOMAIN_SID/USER_RID in tdb. 2. Fetching of unversal groups for given user rid and domain sid from netlogon_unigrp.tdb. Since this is used in both smbd and winbindd, main code is in source/lib/netlogon_uingrp.c. Dependencies are added to AUTH_OBJ as UNIGRP_OBJ and WINBINDD_OBJ as UNIGRP_OBJ. This patch has had a few versions, the final version in particular: Many thanks to Andrew Bartlett for critics and comments, and partly rewritten code. New: - updated fetching code to changed byte order macros - moved functions to proper namespace - optimized memory usage by reusing caller's memory context - enhanced code to more follow Samba coding rules Todo: - proper universal group expiration after timeout (This used to be commit 80c2aefbe7c1aa363dd286a47d50c5d8b4595f43)

2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-18/+33
The auth_authsupplied_info typedef is now just a plain struct - auth_context, but it has been modified to contain the function pointers to the rest of the auth subsystem's components. (Who needs non-static functions anyway?) In working all this mess out, I fixed a number of memory leaks and moved the entire auth subsystem over to talloc(). Note that the TALLOC_CTX attached to the auth_context can be rather long-lived, it is provided for things that are intended to live as long. (The global_negprot_auth_context lasts the whole life of the smbd). I've also adjusted a few things in auth_domain.c, mainly passing the domain as a paramater to a few functions instead of looking up lp_workgroup(). I'm hopign to make this entire thing a bit more trusted domains (as PDC) freindly in the near future. Other than that, I moved a bit of the code around, hence the rather messy diff.

2002-01-01A farily large commit:Andrew Bartlett1-147/+99
- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c - It hasn't been used by anything else since smbpasswd lost its -j - Add a TALLOC_CTX to the auth subsytem. These are only valid for the length of the calls to the individual modules, if you want a longer context hide it in your private data. Similarly, all returns (like the server_info) should still be malloced. - Move the 'ntdomain' module (security=domain in oldspeak) over to use the new libsmb domain logon code. Also rework much of the code to use some better helper functions for the connection - getting us much better error returns (the new code is NTSTATUS). The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for the LUID feilds is sufficient, or if we should do random LUIDs as per the old code. Similarly, I'll move winbind over to this when I get a chance. This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in rpc_client, at least as far as smbd is concerned. While I've given this a basic rundown, any testing is as always appriciated. Andrew Bartlett (This used to be commit d870edce76ecca259230fbdbdacd0c86793b4837)

- 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.
