Lightweight Directory Access Protocol (LDAP) in TypeScript

ASN.1 data structures based on the ASN.1 definitions in IETF RFC 4511, which defines the Lightweight Directory Access Protocol (LDAP).

See the documentation that applies to this library and others to learn how to use this module.

Includes functions for implementing the LDAP syntaxes defined in IETF RFC 4517, functions for evaluating LDAP filters, and functions for converting LDAP data structures to strings for transfer over the wire.

Example

import { BERElement } from "@wildboar/asn1";
import { _decode_LDAPMessage } from "@wildboar/ldap";

// Handle a request received over TCP.
const el = new BERElement();
el.fromBytes(requestBytes); // Throws if a full LDAPMessage is not received yet.
// The above returns the number of bytes read.
const request = _decode_LDAPMessage(el);
if (request.protocolOp === "bindRequest") {
  const bindRequest = request.protocolOp.bindRequest;
  const namestr = Buffer.from(bindRequest.name).toString("utf8");
  console.log(`Binding as ${namestr}`);
}
