OpenLDAP

OpenLDAP is an open source implementation of the Lightweight Directory Access Protocol (LDAP) that provides directory server daemons, client libraries, and utilities for managing distributed directory services. The suite includes slapd (the standalone LDAP daemon), lloadd (a load balancer), protocol libraries, and command-line tools for searching, modifying, and administering directory data. OpenLDAP does not expose a REST API; access is via the LDAP protocol over TCP using SASL, simple bind, or TLS-secured authentication.

OpenLDAP is listed with 1 API on the APIs.io network. Tagged areas include Directory Services, LDAP, Identity, Authentication, and Open Source.

OpenLDAP’s developer surface includes documentation, FAQ, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/openldap: open an issue to ask a question, or submit a pull request to add artifacts.
