Samba 4.22.9 has been released, addressing significant issues with Kerberos authentication and memory leaks in Linux file servers. Administrators are urged to upgrade immediately, as the previous version caused silent failures in Kerberos, leading to user lockouts and fallback to less secure authentication methods. Additionally, the update resolves memory consumption problems in long-running RPC connections, which could lead to system slowdowns or crashes. Finally, critical failover bugs in CTDB clusters have been fixed to ensure stable state synchronization during node switches, preventing file access errors for users
Samba 4.22.9 released
Samba 4.22.9 is out and it fixes a nasty regression where Kerberos authentication would silently break on Linux file servers. Administrators running long-term deployments should upgrade immediately because rpc workers were leaking memory until they consumed all available RAM. The update also patches critical failover bugs in CTDB clusters that caused state synchronization errors during node switches. Get this patch applied before your next maintenance window to keep Windows clients connected without authentication headaches.
