Directory
A directory is a database that stores and organizes identity data like usernames, attributes, group memberships, and access rules. It is the foundational system that identity platforms query to answer 'who is this person and what are they allowed to do.'
# WHAT TEAMS RUN INTO
- —
Multiple directories spring up — Active Directory, LDAP servers, cloud directories, HR systems. Data gets inconsistent and sync jobs fail silently.
- —
Nobody owns the source of truth. A user's email, department, or cost center differs between the HR system and the directory admins trust for access.
- —
Directory queries become a performance bottleneck. Large organizations query the directory thousands of times per second, and slow response times cascade to broken login flows.
# WHY IT MATTERS
Every access decision depends on accurate identity data. A directory is not just a storage system — it is the record of truth for who people are and what they're supposed to access. When directory data drifts from reality, access decisions become decisions made on false information.
