LDAP Core operates the canonical engineering identity directory: the 389DS LDAP fleet, its global replication topology, and the regionalized architecture (REGAL) we are building to replace it by 2027.

- Own LDAP Time Machine and the Identity Data Lake: snapshot pipelines, S3 vending, cross-region log analytics, and IdP security intelligence

- Serve as Tier-1 on-call anchor for directory availability and replication health

- Mentor engineers and raise the technical bar across both teams
