ldifdotnet

Pure managed .NET implementation of LDIF (RFC 2849) — no native OpenLDAP binding. Compatibility with OpenLDAP is proven continuously: CI round-trips OpenLDAP's own test corpus and loads generated data into a real slapd on every push.

Package	What it does
LdifDotNet	Read and write LDIF: streaming LdifReader/LdifWriter, typed content and change records
LdifDotNet.Schema	Parse LDAP schema files (RFC 4512 / slapd.conf format) into a queryable model
LdifDotNet.Generator	Deterministic fake directory data (Bogus-powered), including schema-driven generation
LdifDotNet.PowerShell	ConvertFrom-Ldif / ConvertTo-Ldif / Import-Ldif / Export-Ldif cmdlets (PowerShell 7.6+, via PSGallery)

Quick start

using LdifDotNet;

foreach (var record in LdifReader.ReadFile("dump.ldif"))
    Console.WriteLine(record.Dn);

var entry = new LdifContentRecord("cn=Babs,dc=example,dc=com",
    new LdifAttribute("objectClass", "top", "person"),
    new LdifAttribute("cn", "Babs"),
    new LdifAttribute("sn", "Jensen"));
File.WriteAllText("out.ldif", LdifWriter.WriteToString([entry]));

Import-Ldif dump.ldif | Where-Object Dn -like '*ou=people*' | ConvertTo-Ldif -NoWrap

// Fake data for any schema — point it at the same .schema files slapd uses
var schema = LdapSchema.Load("core.schema", "cosine.schema", "inetorgperson.schema", "eduperson.schema");
var options = new SchemaGeneratorOptions { Seed = 42, OptionalAttributeFill = 0.5 };
options.AuxiliaryClasses.Add("eduPerson");
var people = new SchemaEntryGenerator(schema, options).Entries("inetOrgPerson", 100, "ou=people,dc=example,dc=com");
