The Distributed Authentication UI server must be installed in a supported web container, as listed in OpenSSO Enterprise 8.0 Requirements.
To generate a Distributed Authentication UI server WAR file, your JAVA_HOME environment variable must point to a JDK of version 1.5 or later.
Several other considerations for a Distributed Authentication UI server include:
If you are deploying multiple Distributed Authentication UI servers behind a load balancer, stickiness is not required for the load balancer to talk to only one Distributed Authentication UI server for authentication process completion.
The Windows Desktop SSO and MSISDN authentication modules are not supported through the Distributed Authentication UI.
