2002-08-05This fixes a number of ADS problems, particularly with netbioslessAndrew Tridgell1-3/+12
setups. - split up the ads structure into logical pieces. This makes it much easier to keep things like the authentication realm and the server realm separate (they can be different). - allow ads callers to specify that no sasl bind should be performed (used by "net ads info" for example) - fix an error with handing ADS_ERROR_SYSTEM() when errno is 0 - completely rewrote the code for finding the LDAP server. Now try DNS methods first, and try all DNS servers returned from the SRV DNS query, sorted by closeness to our interfaces (using the same sort code as we use in replies from WINS servers). This allows us to cope with ADS DCs that are down, and ensures we don't pick one that is on the other side of the country unless absolutely necessary. - recognise dnsRecords as binary when displaying them - cope with the realm not being configured in smb.conf (work it out from the LDAP server) - look at the trustDirection when looking up trusted domains and don't include trusts that trust our domains but we don't trust theirs. - use LDAP to query the alternate (netbios) name for a realm, and make sure that both and long and short forms of the name are accepted by winbindd. Use the short form by default for listing users/groups. - rescan the list of trusted domains every 5 minutes in case new trust relationships are added while winbindd is running - include transient trust relationships (ie. C trusts B, B trusts A, so C trusts A) in winbindd. - don't do a gratuituous node status lookup when finding an ADS DC (we don't need it and it could fail) - remove unused sid_to_distinguished_name function - make sure we find the allternate name of our primary domain when operating with a netbiosless ADS DC (using LDAP to do the lookup) - fixed the rpc trusted domain enumeration to support up to approx 2000 trusted domains (the old limit was 3) - use the IP for the remote_machine (%m) macro when the client doesn't supply us with a name via a netbios session request (eg. port 445) - if the client uses SPNEGO then use the machine name from the SPNEGO auth packet for remote_machine (%m) macro - add new 'net ads workgroup' command to find the netbios workgroup name for a realm (This used to be commit e358d7b24c86a46d8c361b9e32a25d4f71a6dc00)
2002-07-14this is a trick to work around the fact that posix does not supplyAndrew Tridgell1-0/+20
a getgr*() function that lists groups without numerating all the group members. Instead of definiing a new nss method (which might cause problems) I added an environment variable WINBIND_GETGRLST that tells winbind not to fill in the group members in a gergrent() request. This can speed up group listing by a factor of 20 or more (on my test system with 50000 groups it reduces the time from an hour to 2 minutes) (This used to be commit e3f73256d31ab9914daae49f41e984a534996870)

2002-05-17A few more trusted domains updates from mimir.Andrew Bartlett1-2/+3
I think we may still need to look at our server enumeration code, but other than that, its much better in the tree than out. Andrew Bartlett (This used to be commit d57a1b4629d12a0374cc6d74dfc6f5d4793fcef8)
2002-04-14The cli_lsa_lookup_{names,sids} functions were returning uselessTim Potter1-6/+4
information when one or more of the names/sids being queried were not resolvable. We now return a list the same length as the parameters passed instead of an array of just the resolvable names/sids. (This used to be commit 245468dbabb7c849ce423cc3cb586fa913d0adfe)
2002-04-11possibly fix the 15000 user problemAndrew Tridgell1-2/+2
I think its caused by a rpc operation failing and us giving invalid data back to the cache layer. Using talloc_zero() should solve this. (This used to be commit dfa990170bb9a665ba48443258e2a87f50baa75c)
2002-04-04Fixed the handle leak in the connection management code (this code is crapJeremy Allison1-2/+11
and should be rewritten, just not now... :-). Jeremy. (This used to be commit 5de792e7e9c2ad1422ac146caba632baa3f4e5c5)

2002-01-31reduced memory usage in winbindd with a rpc backend by using aAndrew Tridgell1-6/+11
separate talloc context for each partial fetch (This used to be commit 9c8a2fe4df21c29c90dc8493dade2b12314234c3)
2002-01-30Removed version number from file header.Tim Potter1-1/+1
Changed "SMB/Netbios" to "SMB/CIFS" in file header. (This used to be commit 6a58c9bd06d0d7502a24bf5ce5a2faf0a146edfa)
2002-01-26Back out some of the less well thought out ideas from last weeks work onAndrew Bartlett1-5/+16
winbind default domains, particulary now I understand whats going on a lot better. This ensures that the RPC client code does as little 'magic' as possible - this is up to the application/user. (Where - for to name->sid code - it was all along). This leaves the change that allows the sid->name code to return domains and usernames in seperate paramaters. Andrew Bartlett (This used to be commit 5dfba2cf536f761b0aee314ed9e30dc53900b691)
2002-01-20This patch makes the 'winbind use default domain' code interact better withAndrew Bartlett1-4/+12
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).

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)
2002-01-10A big tidyup while thinking about getting trusted domains being re-readTim Potter1-4/+4
when they are added or removed on the PDC. - renamed GETPWNAM_FROM_{UID,USER} constants and functions to GETPW{NAM,UID} - renamed GETGRNAM_FROM_{GID,GROUP} constants and functions to GETGR{NAM,GID} - use SIGUSR2 in winbindd for debugging/logging instead of SIGUSR1 in preparation for moving to smbcontrol type messages (not sure whether to ditch this altogether or not) - tidy debugging messages in top level winbind user and group routines - convert talloc_init() to talloc_init_named() - make enumerations of the domain list use the same local variable names (This used to be commit eeb8af9c1a66bfcd80823d7b406acbab79857a16)
2001-12-11removed the start_ndx parameter from group enumerationAndrew Tridgell1-5/+31
I tried testing this by lowering the buffer size in cli_samr_enum_dom_groups() but that didn't work - I think this needs more looking into (This used to be commit 34328e30315e4b42087d0ee11ed0c3fb715bc250)
2001-12-11got rid of start_ndx from query_user_list()Andrew Tridgell1-23/+39
(This used to be commit 1c909afe76566807fb576c965eb869f98e72f2bd)
2001-12-10robustness fixes and moved ccache location into winbindd_ads codeAndrew Tridgell1-0/+8
(This used to be commit 24aa09ff3dd128c6f12b4cb072943ff668a29a67)
2001-12-10winbindd backends can now be marked "consistent" or "inconsistent"Andrew Tridgell1-0/+1
consistent backends (like ADS) always give correct primary group info, so we can play cache tricks to speed things up a lot inconsistent backends (like MSRPC) need to fetch stuff more often (This used to be commit 217c39f23282e20f96a61a0d5a2434b3f5f66a86)
2001-12-10moved the domain sid lookup and enumeration of trusted domains intoAndrew Tridgell1-2/+46
the backends at startup, loop until we get the domain sid for our primary domain, trying every 10 seconds. This makes winbindd handle a room-wide power failure better (This used to be commit 7c60ae59378be1b2af2e57ee3927966a29a797a5)
2001-12-09completely new winbindd cache infrastructureAndrew Tridgell1-5/+9
this one looks like just another winbind backend, and has the following properties: - does -ve and +ve cacheing of all queries - can be disabled with -n switch to winbindd - stores all records packed, so even huge domains are not a problem for a complete cache - handles the server being down - uses sequence numbers for all entries This fixes a lot of problems with winbindd. Serving from cache is now *very* fast. (This used to be commit fddb4f4c04473a60a97212c0c8e143d6a4d68380)
2001-12-05moved the sequence number fetch into the backend, and fetch theAndrew Tridgell1-1/+56
sequence number via ldap when using ads (This used to be commit 9a084f0bb91883224ad44e2b76417d10c15cce42)
2001-12-05finally worked out how to do ldap lookups by binary blobs, so I canAndrew Tridgell1-10/+114
now do searches on SID. This allows me to do a true ldap sid_to_name() function one one function to go! (This used to be commit 7d44aa3915bc88fd2b2f8454f190b11677cbb848)
2001-12-04added lookup_groups() to the ads backendAndrew Tridgell1-2/+2
winbindd/ADS can now do initgroups() (This used to be commit 43edeaca9f3a42699131939ed0d917111f57b678)
2001-12-04moved lookup_usergroups() into the backend structureAndrew Tridgell1-1/+61
(This used to be commit 689f45d2079d06b09947b2cdd314867df98c938d)
2001-12-04added a query_user backendAndrew Tridgell1-1/+58
fixed a winbindd crash when the group membership can't be looked up (This used to be commit 088f4cc5be4a1a38781e4d019146d53993ed8c6f)
2001-12-03changed query_dispinfo to query_user_listAndrew Tridgell1-5/+5
(This used to be commit 80010d80f93cfb32c53a1720c7564fb080846f35)
2001-12-03put sid_to_name behind the winbindd backend interfaceAndrew Tridgell1-1/+33
I spent quite a while trying to work out how to make this call via ldap and failed. I then found that MS servers seem use rpc for sid_to_name, and it works even when in native mode, I ended up just implementing it via rpc (This used to be commit 789833b44e342c0b5de463ed8f9b5f7474a99f27)
2001-12-03added name_to_sid to the backendAndrew Tridgell1-1/+34
(This used to be commit 816e40a51af80a7f703c0451304de406deab3dd8)
2001-12-03added a basic ADS backend to winbind. More work needed, but atAndrew Tridgell1-10/+10
least basic operations work (This used to be commit 88241cab983b2c7db7d477c6c4654694a7a56cd3)
2001-12-03split winbindd_enum_dom_groups into the new backend structureAndrew Tridgell1-0/+130
also created winbindd_rpc.c which contains the functions that have been converted to the new structure. There will soon be a winbindd_ads.c for the ldap backend (This used to be commit e4ccc602ba65838646f2632120069f3274619dd9)
