Configuring SSO Authentication Using SiteMinder
This section describes configuring the ASA to support SSO with SiteMinder. You would typically
choose to implement SSO with SiteMinder if your website security infrastucture already incorporates
SiteMinder. With this method, SSO authentication is separate from AAA and happens once the AAA
process completes.
Prerequisites
• Specifying the SSO server.
• Specifying the URL of the SSO server to which the ASA makes SSO authentication requests.
• Specifying a secret key to secure the communication between the ASA and the SSO server. This key
is similar to a password: you create it, save it, and enter it on both the ASA and the SiteMinder Policy
Server using the Cisco Java plug-in authentication scheme.
Optionally, you can do the following configuration tasks in addition to the required tasks:
• Configuring the authentication request timeout.
• Configuring the number of authentication request retries.
Restrictions
If you want to configure SSO for a user or group for clientless SSL VPN access, you must first configure
a AAA server, such as a RADIUS or LDAP server. You can then set up SSO support for clientless SSL
VPN.
