I haven't been able to find a straightforward way to accomplish this...
Is there a way to set up a notification to an admin email when a specific user logs in?
-There isn't a way to set an alert for a specific user in AuthPoint itself.
-You can set alerts via your firewall if you're logging to a dimension server, but it will be limited to the logon event type (meaning that you'll get a notification for every user that logs in, not just that specific user.

Years ago, I used Syslog logs from my WG firewall, and used a custom program to parse them to generate a daily report of items of interest. At the time, I used the free Kiwi syslog server, which met my needs.
Presumably there is a modern Syslog server which has the ability to parse log entries real time, or can send them to a process/program/script, which can parse them and send emails.
