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()...)

the random workstation trust account password is TOTAL garbage. i mean,
complete garbage. it's nowhere CLOSE to being a UNICODE string. therefore
we can't just take every second character.
created nt_owf_genW() which creates NT#(password) instead of NT#(Unicode(pw)).
followed through to the password setting in srv_samr.c
(This used to be commit 172601b84ae94044b27ded917d4e0e21e47a5a66)
request name.
modified createuser rpcclient command to examine name being added. if it
ends in a $, assume that a workstation trust account is being added.
(This used to be commit 4aea261cb0e5f34255ff83271eb5cadb0eb78bc9)
samr opcode 0x25. _yet_ another failed attempt to get nt5rc2 to join
a samba domain. what _is_ it with this stuff, dammit?
(This used to be commit c3913f8ae272c496fc4519141accf01ee9f1e49e)
1) had to fix samr "create user" and "set user info" (level 23).
2) had to fix netlogon enum trust domains
3) registry key needed \\ in it not \.
(This used to be commit 70b2c1ecbb4fbbb86fea676c80754485aae5ab13)
implementation (NT5) when you discover that your code is trash.
samr_enum_dom_users(), samr_enum_dom_aliases() and samr_enum_dom_groups()
all take a HANDLE for multiple-call enumeration purposes.
(This used to be commit 19490d8b4fb8a103f3df4e6104f6f22937b0c518)
samr_lookup_rids() moved to a dynamic memory structure not a
static one limited to 32 RIDs. cli_pipe.c reading wasn't checking
ERRmoredata when DOS error codes negotiated (this terminates
MSRPC code with prejudice).
(This used to be commit 8976eca2db43576c32069dcda017e8777048e007)
next problem: user group adding not supported so an "access denied"
message is reported instead of "ok" when a new user is created.
(This used to be commit f5f61bd477b4910cb90675c926381342c30a5b16)
used to add workstation to domain. unix account db not modified: only
SAM password db is used.
(This used to be commit 129a9a4d4b74897ed753a697a3aed9b194c25568)
----------------------------
- removed DOM_RID4
- removed SAMR_UNKNOWN_32
- added SAMR_SET_USERINFO (opcode 0x32)
- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)
- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- added mod_sam21pwd_entry()
- preparing to call mod_sam21pwd_entry()
- added "user session key" to user_struct.dc. this is md4(nt#) and is
needed to decode user's clear-text passwords in SAMR_SET_USERINFO.
- split code out in chgpasswd.c to decode 516 byte password buffers.
(This used to be commit 2e58ed742435befe419aa366c4052019fede8c23)
* Added SAMR_LOOKUP_DOMAIN (-> SamrLookupDomainInSamServer)
* Added real SAMR_ENUM_DOM_GROUPS (corresponding to
SamrEnumerateGroupsInDomain). The existing one is just an alias for
SamrQueryDisplayInformation (see below).
* Added three extra info levels to SAMR_QUERY_DISPINFO. Info level 3 is
what was previously SAMR_ENUM_DOM_GROUPS; info levels 4 and 5 are
simple user/group list requests used by Win9x and I suspect (haven't
checked) the "low speed connection" User Manager.
* Added another two aliases for SAMR_QUERY_DISPINFO, opcodes 0x30 and
0x33. Usually the first is with info level 3 and the second 4 but there is
some overlap so indeed these should be implemented as just aliases.
* Return ERRDOS/ERRmoredata on extra data instead of
STATUS_BUFFER_OVERFLOW for Win95's benefit. On a named pipe this results
in an SMBreadX as usual.
Still need to fix SAMR_QUERY_DOMAIN_INFO which has a hard-coded number of
users and groups - which Win95 proceeds to truncate at.
(This used to be commit 7d03e6e21908f3a759a4e65c5edd850622335e3e)
No more ugly static library buffers and all functions take a destination
string length (especially unistrcpy was rather dangerous; we were only
saved by the fact that datagrams are limited in size).
(This used to be commit a1d39af1ce1d451b811dbd7c2ba391214851b87e)
representation in the underlying database: removed this code.
for example, with the nt->unix mapping system (don't know about the ldap
one) if you want "Domain Admins" to appear you _must_ put it in the
domaingroup.map file.
the previous code was adding builtin aliases and well-known groups even
if they weren't in the domain maps. bad idea.
(This used to be commit 56469578a1af0fbcf6edddf94c498c7bbfb385c6)
also needed to use start index properly and generate next index.
both client and server code need to recognise error code 0x105
when there's not enough room to store all the users in one call.
sort this out another time.
(This used to be commit ad58cdfac6b85d9431216e32e532ad4d60f9c6dd)
attempt at taking lib/uid.c and getting a unix security context
change module that is independent of "cnums" and "snums".
a security context is needed for pipes, not just IPC$ or other
services.
- group database API
added add_group/alias_member, del_group/alias_member,
del_group/alias_entry functions. del_builtin_entry() is
deliberately set to NULL to cause an exception, you cannot
delete builtin aliases.
- parse_lsa.c srv_lsa.c
fixed lookup_names code, it was a load of trash and didn't do
anything.
- cmd_samr.c rpcclient.c srv_samr.c
added "deletegroup", "deletealias", "delaliasmem", "delgroupmem",
"addgroupmem", "addaliasmem", "createalias", "creategroup", to
both client and server code.
server code calls into unix stubs right now, which don't actually
do anything. the only instance where they are expected to do
anything is in appliance mode NOT even in the ldap code or anything.
client code modified to call samr_lookup_names() for group code
(because we can) and lsa_lookup_names() for alias code (because
we have to).
- srv_lookup.c
oops, lookup on unsplit name, we got lookup on DOMAIN, DOMAIN\name
instead of DOMAIN, name.
(This used to be commit b8175702ef61b8b37b078f38e81452c00a5e2986)
- samr_enum_dom_users, the first 4 bytes is some sort of garbage,
nt5-beta2 clears them out to zeros whereas nt4 does not.
fixed bug where we were assuming that the first 4 bytes of a
response _had_ to be non-zero.
- cli_lsarpc.c: forgot to append the rid on the lsa_lookup_names()
client call.
- added in "addaliasmem" and "addgroupmem" commands. the addaliasmem
command actually turned out to be a "delaliasmem" :-) :-)
- parse_lsa.c: moved assert array check to after the size of useable
array space is set...
(This used to be commit 165b15a8cacc4bc7cf8cc0b9aaabb6b92cef7fdb)
- renamed do_lsa_xxx to lsa_xxx
- added "enumgroups [-m]" command, enumerates groups, shows members.
- added cmd_sam_add_groupmem(), need to call these in rpcclient.c
- added cmd_sam_add_aliasmem(), need to call these in rpcclient.c
- modified "enumaliases [-m]" command
- improved "enumgroups" and "enumaliases" to display names not just RIDS/SIDs.
- renamed "samr_unknown_12" to "samr_lookup_rids".
- added the following client-side functions:
get_samr_query_groupmem()
get_samr_query_aliasmem()
get_samr_query_groupinfo()
samr_enum_dom_groups()
samr_enum_dom_aliases()
samr_add_aliasmem()
samr_add_groupmem()
- improved display output (display.c)

query.
domain groups now work, hurrah! only thing is that the description is
one character long, don't know why (which is wierd in itself).
(This used to be commit 78a86c64960a7823b0db8b7bebfffabb4a5ba864)
samr_query_aliasmembers (cool!)
util_pwdb.c sids.c nmbd.c server.c smbpasswd.c swat.c :
pwdb_initialise(BOOL is_server) now creates / reads DOMAIN_NAME.SID
if is_server is True, and does LsaQueryInfoPolicy(levels 3 and 5)
to obtain member and pdc sids.
(This used to be commit 3e1eb4f26b67e484b05e1dde94fd4e4dae982631)
- lib/sids.c:
generate_sam_sid() modified to take a domain name: it now
generates "DOMAIN_NAME.SID". reasons:
1) if you run multiple samba servers on the same machine
under different netbios names as members of a domain,
they won't all use the same SID, which is a _big_ mistake
but it would happen _by default_.
2) we have (had) a problem with sid_to_string() and string_to_sid()
which cause SIDs to be incorrectly read. one of the major
reasons for *NOT* making this change was so as not to disrupt
existing users. but as they will be anyway by this bug,
we might as well go ahead.
- passdb/smbpass.c:
wanted to change the meaning of the name in the smbpasswd
file to an "nt" name not a "unix" name. this is probably
not a good idea: reverted this.
- output formatting / bug-fixing in rpcclient query_useraliases code.
(This used to be commit e4930f5f48f8246ceec8add8bf769954a963190c)
- split sam_passwd and smb_passwd into separate higher-order function tables
- renamed struct smb_passwd's "smb_user" to "unix_user". added "nt_user"
plus user_rid, and added a "wrap" function in both sam_passwd and smb_passwd
password databases to fill in the blank entries that are not obtained
from whatever password database API instance is being used.
NOTE: whenever a struct smb_passwd or struct sam_passwd is used, it MUST
be initialised with pwdb_sam_init() or pwd_smb_init(), see chgpasswd.c
for the only example outside of the password database APIs i could find.
- added query_useraliases code to rpcclient.
- dealt with some nasty interdependencies involving non-smbd programs
and the password database API. this is still not satisfactorily
resolved completelely, but it's the best i can do for now.
- #ifdef'd out some password database options so that people don't
mistakenly set them unless they recompile to _use_ those options.
lots of debugging done, it's still not finished. the unix/NT uid/gid
and user-rid/group-rid issues are better, but not perfect. the "BUILTIN"
domain is still missing: users cannot be added to "BUILTIN" groups yet,
as we only have an "alias" db API and a "group" db API but not "builtin-alias"
db API...
(This used to be commit 5d5d7e4de7d1514ab87b07ede629de8aa00519a1)
now need search capability on S-1-5-20, which will need argh, a
"group database API" on S-1-5-20, and the ability to add BUILTIN\Admins
etc to "local group map" argh.
(This used to be commit a24f6eb00ba7486479cbcf7fadf5456521c56179)
