Hi, if you make the LDAP daemon listen on all available interfaces, it will accept connections on the on-demand activated floating-ip.
Or, if you really want to make the ldap daemon listen only on the floating-ip, you would have to write a resoure agent for ldap which will edit the ldap config (add the floating ip) and restart the ldap daemon on a promote, and remove it again on a denote. this way you would have the ldap daemon listening on the fix ip for replication on the slave and only if promoted on the floating-ip.
