The LDAP schema determines which object classes and attributes can be stored in your LDAP database. This page allows you to select which schema types are supported by your server, using the checkbox next to each schema file name. Once you have made changes, click Save to update the OpenLDAP configuration file, then Apply Configuration on the main page to activate them.

Be careful de-selecting existing schema files though, as this may break your LDAP server if objects already exist in the database using the attributes defined in those files. The core schema which contains the most basic LDAP classes cannot be de-selected.

The ordering of schemas is important, as later schemas can only refer to attributes defined previously. You can re-order the list using the up and down arrows on this page, but again this should be done with care for existing schemas in order to avoid breaking the LDAP database.

To see what classes and attributes a schema defines, click on it's View link. If you are familiar with the schema format and want to edit a file, click Edit instead.
