Description:
Plug-in for bind9 that uses LDAP data to fulfill ENUM requests
New versions of bind9 provide a dynamically loaded module interface dubbed dlz_dlopen. This module is linked to bind9 at runtime using the dlz_dlopen. The module accepts ENUM query strings and consults the LDAP database to map the phone number to an email address. It then returns NAPTR records providing SIP and Jabber/XMPP routes based on the email address in LDAP.
