Samba for the 100,000 User Enterprise - Are We There Yet?

Explore the latest developments in Samba for large-scale enterprise deployments in this conference talk from linux.conf.au. Discover how Samba has successfully scaled to handle 124,000 users in a 4-hour benchmark and achieved replication at the 100,000 user scale. Learn about new features coming in Samba 4.10, including Python 3 support, improved audit logging, fine-grained password policies, and backup tools. Gain insights into the challenges faced and solutions implemented for AD DC operation at scale, inter-forest trusts, and replication diagnostics. Understand the transition from TDB to LMDB and its impact on performance. Get an update on the long-standing goal of supporting 100,000 users in Samba and the progress made towards this milestone.
