crasUsername is in the CISCO-REMOTE-ACCESS-MONITOR-MIB listed among the MIBs on that page, but says OID not supported when I try to walk that part of the MIB. I have the same problem because I can get everything (Remote IP, Local IP, VPN Group) but the user name for VPN sessions. With the 3030 VPN Concentrator it was part of the ALTIGA-SESSION-STATS-MIB. Since we've moved our Cisco VPN Client sessions to the ASA we can't monitor those using our SNMP management system. You can see the session information from a command line session on the ASA (show vpn-sessiondb remote), or from the ASDM interface, but that's doesn't help the NOC.
