IKEv1 Remote Access VPN on Cisco ASA for Legacy VPN Client

Even after the release of Cisco AnyConnect Secure Mobility Client which supports SSL VPN in addition to IKEv2 remote-access IPSec VPN, still out there are number of people who use legacy Cisco VPN client to connect IKEv1 remote-access IPSec VPN.
In the present scenario, we have to configure IKEv1 remote access VPN for Sales department and Engineering department of a company. Engineering users will have to be provided with access to web server as well as FTP server, while sales users may only have access to the web server.
