Thanks.

You want to see who uses your remote access VPN?

Command line to see who's currently on:

sh vpn-sessiondb remote

Otherwise, log "warning" messages and above to a syslog and then check the log.

Not currently on. I want to find a user who was on the VPN last month.

How do your users authenticate?

Unless you were keeping logs already, I think the data is gone.

No, that's where they enter their credentials.  The ASA should have an authentication method assigned to the remote access VPN.  (Typically, it's user accounts on the ASA, a RADIUS server, or Kerberos/Active Directory.)

You are correct, users authenticate with the user account on the ASA.

Thanks.

OK.

Then user authentication would be logged on the ASA.  By this time, the buffer will be flushed, so your only hope is that the ASA sends log entries to a syslog server.
