Description
The Web Space Server OpenSSO Add-On may not be able to retrieve an OpenSSO configuration on a GlassFish cluster node located beyond GlassFish LoadBalancer, which causes the OpenSSO Add-On to fail.
See the report for 5634 for more information about this bug.
Solution
Do not deploy OpenSSO in a GlassFish Cluster, but instead use the OpenSSO Session failover capability.
