Does this help ? : http://www.cryptocard.com/index.cfm?pid=493&pagename=LDAP%20Authentication%20Example If you want to have LDAP client binds use cryptocard authentication then you would need a SASL plugin (or possibly PAM, if the exchange is one-way as in SecurID). Cryptocard folks don't seem to have considered this need in their literature (which seems strange since it would give them much wider application support without much work).
