+# Notes on OpenLdap Docker Block
+
+Any ldif files added to the prepopulate subdirectory will be automatically imported into the OpenLdap database. 
+
+The ldif files add three users, `ldapviewer`, `ldapeditor` and `ldapadmin`. Two groups, `admins` and `users`, are added that correspond with the group mappings in the default conf/ldap.toml. `ldapadmin` is a member of `admins` and `ldapeditor` is a member of `users`.
+
+Note that users that are added here need to specify a `memberOf` attribute manually as well as the `member` attribute for the group. The `memberOf` module usually does this automatically (if you add a group in Apache Directory Studio for example) but this does not work in the entrypoint script as it uses the `slapadd` command to add entries before the server has started and before the `memberOf` module is loaded.
+
+After adding ldif files to `prepopulate`:
+
+1. Remove your current docker image: `docker rm docker_openldap_1`
+2. Build: `docker-compose build`
+3. `docker-compose up`
