Root DN for LDAP database

This field is for entering the DN (distinguished name) under which all objects in your LDAP database must be stored. Typically it should be changed to something matching your company or organization's name, like dc=yourcompany,dc=com. But you are free to enter anything as long as it is correctly formatted.

Administration login DN

This is effectively the root user for your LDAP database. It should be a DN under your root set in the above field, like cn=Manager,dc=yourcompany,dc=com.

Administration password

This field shows the current password (possibly encrypted), and an option to enter a new one. If you change the password, the module will use it automatically when connecting to the database to make changes.

If you want your LDAP server to accept TLS encrypted connections, you must first generate an SSL certificate and public key. This can be mostly automated by clicking the Generate SSL Certificate button at the bottom of the page.
