2003-06-30* cleanup more DC name resolution issues in check_*domain_security()Gerald Carter1-68/+2
* 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 Carter1-0/+3
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.

2003-06-25* fix typos in a few debug statementsGerald Carter1-1/+1
* check negative connection cache before ads_try_connect() in ads_find_dc() (This used to be commit 2a76101a3a31f5fca2f444b25e3f0486f7ef406f)
2003-06-25large change:Gerald Carter1-15/+3
*) 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 Carter1-62/+9
* 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 Carter1-12/+33
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. (This used to be commit aac01dc7bc95c20ee21c93f3581e2375d9a894e1)

This includes the 'SIDs Rule' patch, mimir's trusted domains cacheing code, the winbind_idmap abstraction (not idmap proper, but the stuff that held up the winbind LDAP backend in HEAD). Andrew Bartlett (This used to be commit d4d5e6c2ee6383c6cceb5d449aa2ba6c83eb0666)
2003-04-21Merge from HEAD - save the type of channel used to contact the DC.Andrew Bartlett1-3/+5
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'.

2003-03-17Merge from HEAD - make winbindd locking sane again:Andrew Bartlett1-36/+32
Original message: This patch attemptes to clean up winbindd's mutex locking. The current locking scheme in winbind is a complete mess - indeed, the next step should be to push the locking into cli_full_connection(), but I'll leave it for now. This patch works on the noted behaviour that 2 parts of the connection process need protection - and independent protection. Tim Potter did some work on this a little while back, verifying the second case. The two cases are: - between connect() and first session setup - during the auth2 phase of the netlogon pipe setup. I've removed the counter on the lock, as I fail to see what it gains us. This patch also adds 'anonymous fallback' to our winbindd -> DC connection. If the authenticated connection fails (wbinfo -A specifed) - say that account isn't trusted by a trusted DC - then we try an anonymous. Both tpot and mbp like the patch.

2002-03-23Various winbind updates:Andrew Bartlett1-1/+2
- pam_winbind updates from vance, fixing a typo and making some the options work properly. - Extra parinoia in the winbind connection loop - Allow pam_winbind to compile on HP-UX (Don Mcall, more work to do). - Fix up configure.in to use the same method for building the test .so as the Makefile uses.

2002-03-02Allow Samba to trust NT4 Domains.Andrew Bartlett1-2/+4
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)

2002-02-15Winbind cleanup.Andrew Bartlett1-173/+204
This patch fixes the segfaults I introduced in the previous conneciton caching patch. It cleans up the connection cache a *lot* - in particular it adds significant robustness to the operation. If a the DC goes down, we no longer fail the next operation - the code checks if the connection died during one of its own operations on the socket, and restarts the conneciton as required. There is still a memory leak in here somewhere - but this code also cleans up a number of these. Also added is the abilty to sepecify the domain of the 'get around restrict anonymous' user that winbind uses. Andrew Bartlett (This used to be commit 92cbefdf2783bf9dbbb2179c1b2f7cdb802d84a9)
2002-02-11A few small winbind updates:Andrew Bartlett1-14/+55
Add a connection cache to the netlogon pipe. This makes a *massive* difference to the time-per-auth. Also fix up *some* of the memory leaks in other connection caches. Add some debugging messages for the is_connected() code. I'm thinking we should get a client implementation of SMBecho and call it here - as it would allow us to always know the DC is around before we start. Down the debug level for some of the pam_winbind code - I'll probably down it further when I'm finished debugging. Andrew Bartlett (This used to be commit 49d3e476662220775ef8da7db01ea17e77e11b0b)

the "password server" smb.conf parameter when choosing a DC to connect to. Due to the origin of the code in cm_get_dc_name() it wouldn't try additional DCs if the first DC didn't work. This would wedge winbindd if you had "password server = foo1, foo2" and foo1 was down. (This used to be commit fc7ed1b4a8774a6a07a8d8fd08d9d2f15cd5c1dc)
