nuauth-extra 2.2.15-1build1 (lpia binary) in ubuntu intrepid

 NuFW is an authenticating gateway, which means that connections are
 authenticated before being forwarded through the gateway. Classical packet
 filtering systems disregard the identity of the user who may be attempting to
 access the network, instead caring only about the originating IP addresses.
 .
 Nuauth lays on a user database, and an ACL system (which can reside in an LDAP
 directory, or XML/DBM solutions, etc.
 Nuauth receives requests from nufw, and auth packets from users' clients,
 and sends decision to the nufw daemon.
 .
 Nuauth-extra provides extra modules for nuauth.
