sssd/0002-sdap-add-search_bases-option-to-groups_by_user_send.patch
Alexey Tikhonov 9e669db919 Resolves: RHEL-12503 - AD users are unable to log in due to case sensitivity of user because the domain is found as an alias to the email address.
Resolves: RHEL-22288 - ssh pubkey stored in ldap/AD no longer works to authenticate via sssd
Resolves: RHEL-22194 - gdm smartcard login fails with sssd-2.9.3 in case of multiple identities

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.
