Background

Json2Ldap was initially conceived as a lightweight JSON alternative to existing XML-based gateways for providing directory service access to web browsers. Its first official release was in May 2010.[4] In May 2011 development of the software was passed to Nimbus Directory Services.[5]

Interface specification

Json2Ldap provides a JSON web interface for establishing LDAP client connections to one or more directory servers.

Client web interface:

Supported standard LDAP directory operations (as per RFC 4510):

  • Bind (authenticate): simple, plain SASL, digest MD5 SASL, anonymous
  • Search
  • Compare
  • Add a new entry
  • Delete an entry
  • Modify an entry
  • Modify distinguished name (DN)
  • Unbind

Supported extended LDAP controls:

  • Authorisation identity bind control (RFC 3829).
  • Server-side sorting of search results (RFC 2891).
  • Simple paged results (RFC 2696).
