1 Summary
This is the complete installation guide for securing the authentication to your Cisco ASA 5500 solution
with Nordic Edge One Time Password Server, delivering two-factor authentication via SMS to your
mobile phone. For both clientless SSL VPN and Cisco VPN Client. You will be able to test the product
with your existing Cisco ASA 500 and LDAP user database, without making any changes that affect
existing users. The guide will also allow you to make the complete installation effeciently, using a
maximum of 1 hour. Nordic Edge provides several methods for delivering one time passwords, like e-
mail, tokens, mobile clients, prefetch etc. - however in this test we are only going to use SMS.
This is a step-by-step guide that covers the entire installation from A to Z. It is based on the scenario
that you are running your Cisco 5500 solution against Active Directory, and that you install the One
Time Password Server on a Windows Server. The One Time Password Server is platform
independent and works with all other LDAP user databases, like eDirectory, Sun One, Open LDAP
etc. If you are not running Active Directory or Windows and if you have any questions regarding the
slight differences in the installation process, you are most welcome to contact us at
support@nordicedge.se
2 Prerequisites
You will need to have a server available, for example a VMware virtual machine with Windows Server
2003 installed with Ethernet in bridge mode. The server needs to have an ip-address configured and
must also be able to reach your DNS-servers, your Cisco 5500 ASA solution and the Active Directory.
Since the software is quite small and easy to remove, you can also use any existing server in your
network.
3 Important information regarding communication

network or DMZ.
