Some of the ads methods just point to the rpc methods.
This makes winbindd_ads use the reconnect methods instead of
calling the rpc methods directly in order to prevent
negative cache entries for e.g. name_to_sid, when the dc
has closed the connection without sending a reset.

The ads lookup_groupmem() function calls lda_lookupsids to resolve sids
to names. This is tried only once. So in case the connection was broken,
e.g. closed by the server (without a reset packet), there will be an empty
GM/ cache entry for the requested group which will prevent proper working
of access checks among other checks for the expiry period.
This patch works around this problem by retrying once if the lsa_lookupsids
call fails, re-establishing the dc-connection, as we already do in many other
places (e.g. the winbindd retry methods for the rpc layer).

The idmap_tdb backend already provides an interface to remove existing id
mappings. This commit plumbs that ability up through, winbindd, libwbclient,
and wbinfo.
Added new winbindd command:
WINBINDD_REMOVE_MAPPING
Added new libwbclient interfaces:
wbcRemoveUidMapping() and wbcRemoveGidMapping()
Added new wbinfo options:
--remove-uid-mapping
--remove-gid-mapping
Increased libwbclient version to 0.2
Increased winbind interface version to 20

Some AD objects, like Exchange Public Folders, can be members of Security
Groups but do not have a SID attribute. This patch adds more granular return
errors to ads_get_sid_from_extended_dn(). Callers can now determine if a parse
error occured because of bad input, or the DN was valid but contained no SID.
I updated all callers to ignore SIDless objects when appropriate.
Also did some cleanup to the out paths of lookup_usergroups_memberof()

This fixes bug #5865
|
|
|
|
With large groups, getgrent ran into timeouts because after each
single user that was added to the expanded group list, the list
was sorted and made unique.
Now the list is sorted just once after all members have been added.

On some versions of Solaris, we observed a strange effect of close(2)
on a socket: After the server (here winbindd) called close, the client fd
was not marked as readable for select. And a write call to the fd did
not produce an error EPIPE but just returned as if successful.
So while winbindd had called remove_client(), the corresponding smbd
still thought that it was connected, but failed to retrieve answers
for its queries.
This patch works around the problem by forcing the client fd to
the readable state: Just write one byte into the socket before
closing.

otherwise (to clarify we can also pass in structs smaller than
sockaddr_storage, such as sockaddr_in).

We need to initialize all mappings in case we don't find anything.
Simo, please check!

"rescan_trusted_domain".
From analysis by hargagan <shargagan@novell.com> :
"The winbindd_child_died() is also getting called from process_loop() in case of
SIGCHLD signal. In this case it doesn't make the timeout_handler to NULL for
the first request. It then initiate a new request using
schedule_async_request() which installs a new timeout handler for the same
request. In such a case, for a badly unresponsive system both the timeout
handler can be called. For the first call the "private_data" will be cleared
and for another call the timeout handler will be detecting the double free. So,
for such a case as well, the winbindd_child_died() should make the
timeout_handler to NULL."

This API is unusual in that if used to remove a non-list head it nulls out
the next and prev pointers. This is what you want for debugging (don't want
an entry removed from the list to be still virtually linked into it) but
means there is no consistent idiom for use as the next and prev pointers
get trashed on removal from the list, meaning you must save them yourself.
You can use it one way when deleting everything via the head pointer, as
this preserves the next pointer, but you *must* use it another way when not
deleting everything via the head pointer. Fix all known uses of this (the main
one is in conn_free_internal() and would not free all the private data entries
for vfs modules. The other changes in web/statuspage.c and winbindd_util.c
are not strictly neccessary, as the head pointer is being used, but I've done
them for consistency. Long term we must revisit this as this API is too hard
to use correctly.

This option really is essential, as we discover again and again at
customer sites. Due to bugs in winbind some domains are toxic. When
you are installing at a site and a particular domain in a complex
setup causes winbind to segfault or hang then you need a way to
disable that domain and continue.
In an ideal world winbind could handle arbitrarily complex ADS
domains, but we are nowhere near that yet. If we ever get to that
stage then we won't need this option.

With some setups, idmap_tdb2_allocate_id can be called before the
allocate backend is initialised, leading to a segv. This change
ensures that the db is opened in all paths that use it

Before this, "getent group builtin\\administrators" expanded
domain group members in the form DOMAIN\domain\user.

This fixes the output of "getent group" when "winbind use default domain = yes"
with security = ads.

This makes the output of "getent group" of a domain group show the
domain prefix with "security = domain".

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).
