9.7 Auditing Closed User Connections and Deleted eDirectory User Entries

NCP engine logs the connection details when a user logs out gracefully or when it could not find the user entry in eDirectory for the connection. It may happen that a user entry was deleted by the administrator when a user has already logged in to the NCP server.

Security watchdog helps to keep the user connection alive by periodically checking it. If the user connection is unresponsive or unreachable, security watchdog performs either of the following operations:

Schedules the connection for termination
Aborts the connection
Terminates the connection forcefully

watchdog and NCP engine log user details in XML format at /var/opt/novell/log/ncpserv.audit.log and in plain text format at /var/opt/novell/log/ncpserv.log.

The log details include:

Timestamp
Name of the user with eDirectory tree name
Station number
Termination method
Description

NOTE:Novell Client for windows maintains two separate connection for a user who logs in. One of those connections is used to monitor user connection. Hence, while closing or aborting a user connection, the log may print details for each connection.
