Unfortunately, iRedMail doesn't config port number in OpenLDAP config file and rc script, so it won't work for you this way.
Currently, you should use default port 389 to complete installation first, then update necessary files to make OpenLDAP listen on port 7389, update related config files to make Postfix/Dovecot/Amavisd/etc connect to LDAP server through port 7389.
