How to configure/store NAS clients in LDAP instead of clients.conf

Hi guys, I've been looking for the past two days all over the web regarding this subject. Sorry if this question has been posted before. With rlm_sql im able to store NAS clients on a SQL table. I want to do the same but with ldap. is there a way that rlm_ldap can lookup NAS clients from my ldap server? Thanks in advance. Lenir
