The adex idmap/nss_info plugin is an adapation of the Likewise
Enterprise plugin with support for OU based cells removed
(since the Windows pieces to manage the cells are not available).
This plugin supports
* The RFC2307 schema for users and groups.
* Connections to trusted domains
* Global catalog searches
* Cross forest trusts
* User and group aliases
Prerequiste: Add the following attributes to the Partial Attribute
Set in global catalog:
* uidNumber
* uid
* gidNumber
A basic config using the current trunk code would look like
[global]
idmap backend = adex
idmap uid = 10000 - 19999
idmap gid = 20000 - 29999
idmap config US:backend = adex
idmap config US:range = 20000 - 29999
winbind nss info = adex
winbind normalize names = yes
winbind refresh tickets = yes
template homedir = /home/%D/%U
template shell = /bin/bash

user object in AD to be the username alias.
For example:
$ net ads search "(uid=coffeedude)"
distinguishedName: CN=Gerald W. Carter,CN=Users,DC=pink,DC=plainjoe,DC=org
sAMAccountName: gcarter
memberOf: CN=UnixUsers,CN=Users,DC=pink,DC=plainjoe,DC=org
memberOf: CN=Domain Admins,CN=Users,DC=pink,DC=plainjoe,DC=org
memberOf: CN=Enterprise Admins,CN=Users,DC=pink,DC=plainjoe,DC=org
memberOf: CN=Schema Admins,CN=Users,DC=pink,DC=plainjoe,DC=org
uid: coffeedude
uidNumber: 10000
gidNumber: 10000
unixHomeDirectory: /home/gcarter
loginShell: /bin/bash
$ ssh coffeedude@192.168.56.91
Password:
coffeedude@orville:~$ id
uid=10000(coffeedude) gid=10000(PINK\unixusers) groups=10000(PINK\unixusers)
$ getent passwd PINK\\gcarter
coffeedude:*:10000:10000::/home/gcarter:/bin/bash
$ getent passwd coffeedude
coffeedude:*:10000:10000::/home/gcarter:/bin/bash
$ getent group PINK\\Unixusers
PINK\unixusers:x:10000:coffeedude

* Port the Likewise Open idmap/nss_info provider (renamed to
idmap_hash).
* uids & gids are generated based on a hashing algorithm that collapse
the Domain SID to a 31 bit number. The reverse mapping from the
high order 11 bits to the originat8ing sdomain SID is stored in
a has table initialized at start up.
* Includes support for "idmap_hash:name_map = <filename>" for the
name aliasing layer. The name map file consist of entries in
the form "alias = DOMAIN\name"
|
|
* Ensures that all points an which a name is received or returned
to/from a client passes through the name aliases layer (users
and groups).
|
|
* Add support user and group name aliasing by expanding
the ws_name_replace() and ws_name_return() functions.
The lookup path is
aliases -> qualified name -> SID
SID -> fully qualified name -> alias
In other words, the name aliasing support is a thin layer
built on top of SID/NAME translation.
* Rename the ws_name_XX() functions to normalize_name_map()
and normalize_name_unmap(). Chaneg interface to return
NTSTATUS rather than char *.
* Add associated cache validation functions.

Make sure that usernames are parsed using the correct separator.
Otherwise group memeberships in winbind may be result broken.

request.extra_data is not freed if there is no extra_data in response or
when there is some error happens in processing. This patch will free the
buffer right after processing a request before sending back a response.

This is a fix for a few small inefficiencies/bugs in the get_dcs() path.
* because the third add_one_dc_unique() loop was outside the ADS check all DCs
returned from the non-sitename lookup were being tacked onto the dc_name_ip
list twice.
* add_one_dc_unique() now checks if the given IP address already exists before
adding it to the list, making the returned list actually unique
* added more thorough doxygen comment headers

The scanner did not figure out that we always have a primary domain, so it
complained about us potentially passing a NULL pointer down to
set_domain_online_request() where it is dereferenced.
Make the code a bit clearer.

farm failures when winbindd connects as guest.
This one took a *lot* of tracking down :-).

Fix segv when talking to parent DC (joined to child domain).
The root cause was
(a) storing the parent domain in the cli_state struct caused
the NTLMSSP pipe bind to fail which made us fallover to
the schannel code path
(b) the dcinfo pointer in cm_get_schannel_dcinfo() was returning
NULL even though the function indicated success.

reconnect code to cope with rebooting a DC. This
replaces the code I asked Volker to revert.
The logic is pretty simple. It adds a new parameter,
"winbind reconnect delay", set to 30 seconds by
default, which determines how long to wait between
connection attempts.
To avoid overwhelming the box with DC-probe
forked children, the code now keeps track of
the DC probe child per winbindd_domain struct
and only starts a new one if the existing one
has died.
I also added a little logic to make sure the
dc probe child always sends a message whatever
the reason for exit so we will always reschedule
another connect attempt.
Also added documentation.
Jeremy.

lookup_domain_name(). This new function accept separated
strings for domain and name.

was asking for a winbindd name to SID lookup of
"Unix Group\name" where "name" was also a valid username,
the winbindd passdb lookup of that name was losing the
domain string info before calling lookup name (ie. lookup_name()
was being called with just the string "name", not the
full string "Unix Group\name").
The passdb backend of winbindd has to cope with
not only names from it's own global SAM domain,
but it does lookups for BUILTIN and "Unix User"
and "Unix Group" also, so making it guess by
losing the domain string is "A Bad Idea" (tm) :-).
Note that as winbind globally calls winbind_off()
at startup, it's safe for winbind to call sys_getgrnam()
to do the "Unix Group" lookup from inside lookup_name().

should never include the user SID.
The comment for the function in winbindd/winbindd_ads.c says
/* Lookup groups a user is a member of. */
The following patch makes the wbinfo calls return the correct data
before and after a login.
wbinfo --user-domgroups and --user-sids

1. use the return value that idmap_tdb2_open_perm_db() gives us
2. don't delete frep the local db if deleting from the perm db failed.
3. fix wrong interpretation of return value of the local delete

This is a band-aid for the rather convoluted offline/online mess in winbind
right now. Winbind re-uses the offline functionality that is targeted at domain
client installations on laptops to not overload disfunctional DCs. It uses the
winbind cache timeout as the retry timeout after a DC reboot.
I am using a parametric options because when this mess is cleaned up, that
parameter needs to go away again.
I'd recommend to use something like
winbind:online check timeout = 30
in typical LAN environments. This means a reconnect is attempted every 30
seconds.
