The information of a subdomain will use magic private groups (mpg) or
not will be stored together with other information about the domain in
the cache.
|
|
new_subdomain() will create a new domain object and should not be used
anymore in the priovder code directly. Instead a reference to the domain
from the common domain object should be used.

Currently the range for Posix IDs stored in an LDAP server is unbound.
This might lead to conflicts in a setup with AD and trusts when the
configured domain uses IDs from LDAP. With the two noe options this
conflict can be avoided.

|
This patch reuses the code from IPA provider to make sure that
domain-realm mappings are written even for AD sub domains.
|
|
We tried to use the GC address even for kinit which gave us errors like:
"Realm not local to KDC while getting initial credentials".
This patch adds a new AD_GC service that is only used for ID lookups,
any sort of Kerberos operations are done against the local servers.

The options are stored in ad_options->auth_ctx->opts, this member was
completely unused and confusing.

sdom was only ever guaranteed to be set when a new domain was being
created. sditer is a valid pointer in both cases, so just use that.

The patch introduces a new Kerberos provider option called
krb5_use_kdcinfo. The option is true by default in all providers. When
set to false, the SSSD will not create krb5 info files that the locator
plugin consumes and the user would have to set up the Kerberos options
manually in krb5.conf

Looks up trusted domain objects in the LDAP and stores them as AD
subdomains.
Currently only trusted domains that run NT5 or newer from the same forest
are looked up and stored.

Some lookups should be performed from GC only -- for example trusted
users are only present in the Global Catalog, while some lookups should
be performed from LDAP only as not all objects or attributes are
replicated to Global Catalog.
This patch adds a generic failover mechanism for identity lookups in the
AD provider that allows to choose the appropriate source and even fail over
to the other source if available.
|
|
When fixed host names of AD servers are configured in the config file,
we can't know (unlike when service discovery is at play) if the servers
are Global Catalogs or not. This patch adds a private data to servers
read from the config file that denote whether the server can be tried
for contacting the Global Catalog port or just LDAP. The GC or LDAP URIs
are generated based on contents of this private data structure.
Because SSSD sticks to a working server, we don't have to disable or
remove the faulty GC servers from the list.

Previously an sdap_id_ctx was always tied to one domain with a single
set of search bases. But with the introduction of Global Catalog
lookups, primary domain and subdomains might have different search
bases.
This patch introduces a new structure sdap_domain that contains an sssd
domain or subdomain and a set of search bases. With this patch, there is
only one sdap_domain that describes the primary domain.
|
|
Instead of using the default connection from the sdap_id_ctx, allow the
caller to specify which connection shall be used for this particular
request. Again, no functional change is present in this patch, just
another parameter is added.
|
|
With some LDAP server implementations, one server might provide
different "views" of the identites on different ports. One example is
the Active Directory Global catalog. The provider would contact
different view depending on which operation it is performing and against
which SSSD domain.
At the same time, these views run on the same server, which means the same
server options, enumeration, cleanup or Kerberos service should be used.
So instead of using several different failover ports or several
instances of sdap_id_ctx, this patch introduces a new "struct
sdap_id_conn_ctx" that contains the connection cache to the particular
view and an instance of "struct sdap_options" that contains the URI.
No functional changes are present in this patch, currently all providers
use a single connection. Multiple connections will be used later in the
upcoming patches.

|
Instead of using boolean variables to denote whether the call is adding
a primary or a secondary server, use a function wrapper that tells what
it's doing by its name.

The dyndns init function was starting the timer even if the updates were
set to False. This patch splits the init of dynamic updates and the
timer into two functions so that the back end can start the updates
separately from reading the options.

This commit adds new option ldap_disable_range_retrieval with default value
FALSE. If this option is enabled, large groups(>1500) will not be retrieved and
behaviour will be similar like was before commit ae8d047122c
"LDAP: Handle very large Active Directory groups"

setup_child() was accepting a parameter it didn't use. Also the function
name was too generic, so I added a sdap prefix.

In function ad_subdomains_get_netlogon_done:
If variable "reply_count" is zero then variable "reply" will not be
initialized. Therefore we should not continue.

For various features either the flat/short/NetBIOS domain name or the
domain SID is needed. Since the responders already try to do a subdomain
lookup when and known domain name is encountered I added a subdomain
lookup to the AD provider which currently only reads the SID from the
base DN and the NetBIOS name from a reply of a LDAP ping. The results
are written to the cache to have them available even if SSSD is started
in offline mode. Looking up trusted domains can be added later.
Since all the needed responder code is already available from the
corresponding work for the IPA provider this patch fixes

Because we now always store SIDs in the LDAP provider, we also need to
always initialize the ID mapping context even if ID mapping itself is
off.

Implements dynamic DNS updates for the AD provider. By default, the
updates also update the reverse zone and run periodically every 24
hours.

Enterprise principals are currently most useful for the AD provider and
hence enabled here by default while for the other Kerberos based
authentication providers they are disabled by default.
If additional UPN suffixes are configured for the AD domain the user
principal stored in the AD LDAP server might not contain the real
Kerberos realm of the AD domain but one of the additional suffixes which
might be completely randomly chooses, e.g. are not related to any
existing DNS domain. This make it hard for a client to figure out the
right KDC to send requests to.
To get around this enterprise principals (see
http://tools.ietf.org/html/rfc6806 for details) were introduced.
Basically a default realm is added to the principal so that the Kerberos
client libraries at least know where to send the request to. It is not
in the responsibility of the KDC to either handle the request itself,
return a client referral if he thinks a different KDC can handle the
request or return and error. This feature is also use to allow
authentication in AD environments with cross forest trusts.

We set a plugin during an initialization of ID provider, which
is an authoritative provider for a plugin choice. The plugin is
set only once. When other provider is initalized (e.g. id = IPA,
sudo = LDAP), we do not overwrite the plugin.
Since sssm_*_id_init() is called from all module constructors,
this patch relies on the fact, that ID provider is initialized
before all other providers.

Add option to fallback to fetch local users if rfc2307is being used.
This is useful for cases where people added local users as LDAP members
and rely on these group memberships to be maintained on the local host.
Disabled by default as it violates identity domain separation.
