As part of the + re-authentication, Samba receives the current group + membership information and is expected to reflect this + change in further SMB request processing. + + For historic reasons, Samba maintains a cache of + associations between a user's impersonation information and + connected shares. A recent change in this cache caused Samba + to not reflect group membership changes from session + re-authentication when processing further SMB requests. + + As a result, when an administrator removes a user from a + particular group in Active Directory, this change will not + become effective unless the user disconnects from the server + and establishes a new connection. + + +Changes since 4.21.5 +-------------------- + +o Douglas Bagnall <douglas.bagn...@catalyst.net.nz> + * BUG 15774: Running "gpo manage motd set" twice fails with backtrace. + * BUG 15829: samba-tool gpo backup creates entity backups it can't read. + * BUG 15839: gp_cert_auto_enroll_ext.py has problem unpacking GUIDs with + prepended 0's. + +o Ralph Boehme <s...@samba.org> + * BUG 15707: CVE-2025-0620 [SECURITY] smbd doesn't pick up group membership + changes when re-authenticating an expired SMB session. + * BUG 15767: Deadlock between two smbd processes. + +o Pavel Filipenský <pfilipen...@samba.org> + * BUG 15727: net ad join fails with "Failed to join domain: failed to create + kerberos keytab". + +o Andreas Hasenack <andreas.hasen...@canonical.com> + * BUG 15774: Running "gpo manage motd set" twice fails with backtrace. + +o Volker Lendecke <v...@samba.org> + * BUG 15841: Wide link issue in samba 4.22. + +o Stefan Metzmacher <me...@samba.org> + * BUG 15767: Deadlock between two smbd processes. + * BUG 15851: dcerpcd not able to bind to listening port. + +o Anoop C S <anoo...@samba.org> + * BUG 15819: vfs_ceph_snapshots fails to list snapshots for entries at any + level beyond share root. + +o Martin Schwenke <mschwe...@ddn.com> + * BUG 15858: CTDB does not put nodes running NFS into grace on graceful + shutdown. + + +####################################### +Reporting bugs & Development Discussion +####################################### + +Please discuss this release on the samba-technical mailing list or by +joining the #samba-technical:matrix.org matrix room, or +#samba-technical IRC channel on irc.libera.chat. + +If you do report problems then please try to send high quality +feedback.
