Subject: [PATCH 2/3] sdap: add search_bases option to groups_by_user_send()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AD handles users and computer objects very similar and so does SSSD's
GPO code when lookup up the host's group-memberships. But users and
computers might be stored in different sub-tree of the AD LDAP tree and
if a dedicated user search base is given with the ldap_user_search_base
option in sssd.conf the host object might be in a different sub-tree. To
make sure the host can still be found this patch uses the base DN of
the LDAP tree when searching for hosts in the GPO code.

Subject: [PATCH] sysdb: do not fail to add non-posix user to MPG domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SSSD does not handle the root user (UID==0) and treats all accounts with
UID 0 as non-Posix accounts. The primary GID of those accounts is 0 as
well and as a result for those accounts in MPG domains the check for a
collisions of the primary GID should be skipped. The current code might
e.g. cause issues during GPO evaluation when adding a host account into
the cache which does not have any UID or GID set in AD and SSSD is
configured to read UID and GID from AD.

Subject: [PATCH 3/3] sdap: add naming_context as new member of struct
sdap_domain
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The naming_context could be a more reliable source than basedn for the
actual base DN because basedn is set very early from the domain name
given in sssd.conf. Although it is recommended to use the fully
qualified DNS domain name here it is not required. As a result basedn
might not reflect the actual based DN of the LDAP server. Also pure LDAP
server (i.e. not AD or FreeIPA) might use different schemes to set the
base DN which will not be based on the DNS domain of the LDAP server.

Subject: [PATCH] pam: fix SC auth with multiple certs and missing login name
While introducing the local_auth_policy option a quite specific use-case
was not covered correctly. If there are multiple matching certificates
on the Smartcard, 'local_auth_policy = only' is set and GDM's Smartcard
mode was used for login, i.e. there is no user name given and the user
has to be derived from the certificate used for login, authentication
failed. The main reason for the failure is that in this case the
Smartcard interaction and the user mapping has to be done first to
determine the user before local_auth_policy is evaluated. As a result
when checking if the authentication can be finished the request was in
an unexpected state because the indicator for local Smartcard
authentication was not enabled.

Subject: [PATCH] ad-gpo: use hash to store intermediate results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Currently after the evaluation of a single GPO file the intermediate
results are stored in the cache and this cache entry is updated until
all applicable GPO files are evaluated. Finally the data in the cache is
used to make the decision of access is granted or rejected.
If there are two or more access-control request running in parallel one
request might overwrite the cache object with intermediate data while
another request reads the cached data for the access decision and as a
result will do this decision based on intermediate data.
To avoid this the intermediate results are not stored in the cache
anymore but in hash tables which are specific to the request. Only the
final result is written to the cache to have it available for offline
authentication.

Subject: [PATCH] ad: refresh root domain when read directly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the domain object of the forest root domain cannot be found in the
LDAP tree of the local AD domain SSSD tries to read the request data
from an LDAP server of the forest root domain directly. After reading
this data the information is stored in the cache but currently the
information about the domain store in memory is not updated with the
additional data. As a result e.g. the domain SID is missing in this data
and only becomes available after a restart where it is read from the
cache.
With this patch an unconditional refresh is triggered at the end of the
fallback code path.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

During two-factor authentication (OTP) krb5_child should use use the
dedicated OTP auth types SSS_AUTHTOK_TYPE_2FA and
SSS_AUTHTOK_TYPE_2FA_SINGLE exclusively and should not try password or
other types.
The special handling needed of ssh under certain conditions are
documented in the code and the man page.
