Currently some manual steps are needed on a FreeIPA to switch from one
view to another. With this patch the IPA provider checks at startup if
the view name changed and does the needed steps automatically. Besides
saving the new view name this includes removing the old view data and
marking the user and group entries as invalid.

Currently overrides were only available for sub-domains, e.g. trusted AD

Recently the uuid attributes for user and groups were removed because
it was found that there are not used at all and that some of them where
causing issues (https://fedorahosted.org/sssd/ticket/2383).
The new views/overrides feature of FreeIPA uses the ipaUniqueID attribute
to relate overrides with the original IPA objects. The previous two
patches revert the removal of the uuid attributes from users and groups
with this patch set the default value of these attributes to
ipaUniqueID from the IPA provider, to objectGUID for the AD provider and
leaves them unset for the general LDAP case to avoid issues like the one
from ticket #2383.

With this patch the SSH public key override attribute is read from the

Currently the component of the IPA provider which reads the AD user and
group attributes in ipa-server-mode uses default settings for the LDAP
related attributes. As a result even if ldap_user_extra_attrs is defined
in sssd.conf no extra attributes are read from AD.
With the patch the value if ldap_user_extra_attrs is inherited to the AD
subdomains to allow them to read extra attributes as well.

dfb34c6c82ed5014599bf70de6791e6d79106fc2 changed object class
of IPA groups from posixGroups to more general groupOfNames.
However, this object class is used also for roles, permissions and

If the name or the POSIX ID of a user or a group is overridden the
search request for those objects have to check the overide objects first
before looking up the original objects.
This patch adds a new request for the IPA sub-domain users which checks
the overrides first if
- SSSD is running in ipa-server-mode and a name or a POSIX ID is
searched, since we do not override the SIDs we can skip the search in
the override tree here
- if the responder indicates it has not found the corresponding object
in the cache and the input might be an override name or ID and not the
original one of an object.
If an override object was found the SID is extracted from the anchor
attribute and the original object is search by its SID. If no override
object was found the original object is search with the original input
and finally it is checked if an override object exits for the found
object.

With this patch the IPA provider will check if overrides exists for the
given view during the lookup of users and groups from trusted domains.
In ipa-server-mode the default view is automatically applied and written
to the cache. On IPA clients which use the extdom plugin for user and
group lookups the override data is saved separately and the original
object and the override data are linked with DN attributes for faster
reference.

Initially the extdom plugin was only used to translate SIDs of AD user
and groups to names or POSIX IDs. On IPA clients group memberships were
resolved with the help of the PAC in the Kerberos ticket which required
that the user has logged in at least once. Home directory and the login
shell were auto generated.
The new version of the extdom plugin can return the complete list of
group memberships of a user and the list of all members of a group.
Additionally the gecos field, home directory and login shell are
returned together with an optional list of key-value pairs for arbitrary
data which is written unmodified to the cache.

apply_subdomain_homedir() didn't handle the situation where an entity
that doesn't match was requested from the cache. For user and group
lookups this wasn't a problem because the negative match was caught
sooner.
But SID lookups can match either user or group. When a group SID was
requested, the preceding LDAP request matched the SID and stored the
group in the cache. Then apply_subdomain_homedir() only tried to search
user by SID, didn't find the entry and accessed a NULL pointer.
A simple reproducer is:
$ python
>>> import pysss_nss_idmap
>>> pysss_nss_idmap.getnamebysid(group_sid)
The group_sid can be anything, including Domain Users (XXX-513)
