Applications that are PAM-aware do not need to incorporate any logic to deal with back-ends such as databases, LDAP service, password files, WS-Security enabled web services or other back-ends that have not been invented yet. By using PAM, applications segregate the back-end integration logic from their own. All they need to do is call PAM functions.
