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 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.
