+# OpenLDAP
+
+Not available until the next release of testcontainers-go <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+## Introduction
+
+The Testcontainers module for OpenLDAP.
+
+## Adding this module to your project dependencies
+
+Please run the following command to add the OpenLDAP module to your Go dependencies:
+
+```
+go get github.com/testcontainers/testcontainers-go/modules/openldap
+```
+
+## Usage example
+
+<!--codeinclude-->
+[Creating a OpenLDAP container](../../modules/openldap/examples_test.go) inside_block:runOpenLDAPContainer
+<!--/codeinclude-->
+
+## Module reference
+
+The OpenLDAP module exposes one entrypoint function to create the OpenLDAP container, and this function receives two parameters:
+
+```golang
+func RunContainer(ctx context.Context, opts ...testcontainers.ContainerCustomizer) (*OpenLDAPContainer, error)
+```
+
+- `context.Context`, the Go context.
+- `testcontainers.ContainerCustomizer`, a variadic argument for passing options.
+
+### Container Options
+
+When starting the OpenLDAP container, you can pass options in a variadic way to configure it.
+
+#### Image
+
+If you need to set a different OpenLDAP Docker image, you can use `testcontainers.WithImage` with a valid Docker image
+for OpenLDAP. E.g. `testcontainers.WithImage("bitnami/openldap:2.6.6")`.
+
+{% include "../features/common_functional_options.md" %}
+
+### Container Methods
+
+The OpenLDAP container exposes the following methods:
+
+#### ConnectionString
+
+This method returns the connection string to connect to the OpenLDAP container, using the `1389` port.
+
+<!--codeinclude-->
+[Get connection string](../../modules/openldap/openldap_test.go) inside_block:connectionString
+<!--/codeinclude-->
+
+#### LoadLdif
+
+This method loads an ldif file in the OpenLDAP server.
+It returns and error if there is any problem with the ldif file loading process.
+
+<!--codeinclude-->
+[Load ldif](../../modules/openldap/openldap_test.go) inside_block:loadLdif
+<!--/codeinclude-->
+
+#### Initial Ldif
+
+If you would like to load an ldif at the initialization of the openldap container, you can use `WithInititialLdif` function.
+The file will be copied after the container is started and loaded in openldap.
