Intro
SYNRC LDAP is designed for extreme performance and simplicity. At just 300 lines of Elixir code,
it provides a full-featured LDAPv3 server capable of handling large-scale directory services with various backends.
The server leverages Erlang/OTP for concurrency and reliability, making it robust for mission-critical applications.

Services & Protocols
- LDAPv3 (RFC 4511) — core protocol support for directory access.
- LDIF (RFC 2849) — standard data interchange format for LDAP.
- CONF — flexible configuration management for server instances.
- SCHEMA — robust support for standard and custom LDAP schemas.
- ARCH — scalable storage architecture for distributed environments.
MESIA Architecture
MESIA is the high-performance storage engine architecture used in SYNRC LDAP, designed for efficient prefix-searchable data access.
Directory Table — Prefix-searchable DN paths with MD5 hashing for rapid lookups.
Attributes Table — Selectable attribute information per RDN with optimized sub-indexing.
Subschema Subentry — Integration with
ou=schema for persistent metadata.
Unlike traditional monolithic LDAP databases, MESIA provides a distributed framework where attributes are stored
efficiently across various backends like RocksDB, ensuring minimal overhead and maximum scalability for NVME storage.
