The next major release of SSSD will include support for more advanced AD
features for domain members. This includes site support and trusted domains.
Additionally it will include a plugin for the cifs-utils package which would
allow a CIFS client to use SSSD for lookups which were currently only possible
with winbind.
== Detailed description ==
So far SSSD development of AD provider concentrated on doing the user and
group lookups for the joined domain efficiently with high performance. With the
next major release of SSSD support for some features which are specific to AD
domain will be added. This includes:
* Site support: AD domains which include different physical locations can be
split into sites. Each site represents a single physical location. With
specially crafted DNS service record lookups an AD client can find the nearest
domain controller, i.e. the domain controller in its site. This helps to keep
network traffic local and allows clients to talk to the server with the lowest
latency.
* Trusted domains: currently the SSSD AD provider can only look up user and
groups of the joined domain. With the support of Global Catalogs all users and
groups of the forest the AD domain belongs to are available. Additionally it
is planned to follow cross forest trust to look up users and groups in trusted
forests.
* CIFS client integration: in version 5.9 of the cifs-utils a plugin
interface for ID mapping was added. This allows cifs-utils to use other
services than winbind for those lookups. While those lookups are not needed
for basic operation, i.e. accessing files from a Linux client on a
Windows/Samba file server, they are needed e.g. when accessing and modifying
access control lists (ACLs).
