If there are member domains in a trusted forest which are DNS-wise not
proper children of the forest root the IPA KDC needs some help to
determine the right authentication path. In general this should be done
internally by the IPA KDC but this works requires more effort than
letting sssd write the needed data to the include file for krb5.conf.
If this functionality is available for the IPA KDC this patch might be
removed from the sssd tree.

In order to fix https://fedorahosted.org/sssd/ticket/2093 the name of
the forest must be known for a member domain of the forest.

This function will return head of the domain list.

This function will parse object name into name and domain
name part and return appropriate sss domain.

This function takes domain SID (doesn't have the last component)
or object SID (have all components) and returns subdomain.
The subdomain is found by comparing domain->domainid with the SID.
E.g.
domain SID: S-1-5-21-3940105347-3434501867-2690409756
object SID: S-1-5-21-3940105347-3434501867-2690409756-513

The enumerate flag will be read from the cache for subdomains and
the domain object will be created accordingly.

The mpg flag will be read from the cache for subdomains and the domain
object will be created accordingly.

This patch reuses the code from IPA provider to make sure that
domain-realm mappings are written even for AD sub domains.

Otherwise dom may be set to NULL and we will segfault when
dereferencing dom.

- Use a double-linked list for domains and subdomains.
- Never remove a subdomain, simply mark it as disabled if it becomes
unused.
- Rework the way subdomains are refreshed.
Now sysdb_update_subdomains() actually updates the current subdomains
and marks as disabled the ones not found in the sysdb or add new ones
found. It never removes them.
Removal of missing domains from sysdb is deferred to the providers,
which will perform it at refresh time, for the ipa provider that is
done by ipa_subdomains_write_mappings() now.
sysdb_update_subdomains() is then used to update the memory hierarchy
of the subdomains.
- Removes sysdb_get_subdomains()
- Removes copy_subdomain()
- Add sysdb_subdomain_delete()

Use this function instead of explicitly calling domain->next
This function allows to get the next primary domain or to descend into the
subdomains and replaces also get_next_dom_or_subdom()

Now that the sysdb context does not contain anymore domain related data
we can simply stop creating faxe sysdb context and just reference the
parent context.
|
|
A sysdb contains now multiple domains, but the mpg property is a
property of a specific domain not of the underlying database.
|
|
Also allows us to remove sysdb_subdom_get<pw/gr>nam() wrappers and restore
fqnames proper value in subdomains, by testing for a parent domain being
present or not.
|
|
Bring it out of sysdb, which will slowly remove internal dependencies on
domains and instead will always require them to be passed by callers.

The original sysdb code had a strong assumption that only users from one
domain are saved in the databse, with the subdomain feature, we have
changed reality, but have not adjusted all the code arund the sysdb calls
to not rely on the original assumption.
One of the side effects of this incongrunece is that currently group
memberships do not return fully qualified names for subdomain users as they
should.
In oreder to fix this and other potential issues surrounding the violation
of the original assumption, we need to fully qualify subdomain user names.
By savin them fully qualified we do not risk aliasing local users and have
group memberhips or other name based matching code mistake a domain user
with subdomain usr or vice versa.

Currently the only type of supported sub-domains are AD domains which
are not case-sensitive. To make it easier for Windows user we make
sub-domains case-insensitive as well which allows to write the username
in any case at the login prompt.
If support for other types of sub-domains is added it might be necessary
to set the case-sensitive flag based on the domain type.

* Allows different user/domain qualified names for different
domains. For example Domain\User or user@domain.
* The global re_expression and full_name_format options remain
as defaults for the domains.
* Subdomains get the re_expression and full_name_format of
their parent domain.

New option pwd_expiration_warning is introduced which can be set per
domain and can override the value specified by the original
pam_pwd_expiration_warning.
If the value of expiration warning is set to zero, the filter isn't
apllied at all - if backend server returns the warning, it will be
automatically displayed.
Default value for Kerberos: 7 days
Default value for LDAP: don't apply the filter
Technical note: default value when creating the domain is -1. This is
important so we can distinguish between "no value set" and 0. Without
this possibility it would be impossible to set different values for LDAP
and Kerberos provider.

subdomain_homedir - if set, it contains default value, can be overriden
in further processing
